+          
+
+        
+
+
+<p>The <em>Command &amp; Control</em> API of Eclipse Hono&trade; is used by <em>Business Applications</em> to send commands to connected devices.</p>
+
+<p>Commands can be used to trigger actions on devices. Examples include updating a configuration property, installing a software component or switching the state of an actuator.</p>
+
+<p>Hono distinguishes two types of commands. The first type is <em>one-way</em> only. In this case the sender of the command does not expect the device to send back a message in response to the command. This type of command is referred to as a <em>one-way command</em> in the remainder of this page. One-way commands may be used to e.g. <em>notify</em> a device about a change of state.</p>
+
+<p>The second type of commands expects a <em>response</em> to be sent back from the device as a result of processing the command. In this case the response contains a <em>status</em> code which indicates whether the command could be processed successfully. If so, the response may also include data representing the result of processing the command. This type of command is plainly referred to as a <em>command</em> because it represents the default case.</p>
+
+<p>The Command &amp; Control API for Kafka is an alternative to the <a href="/hono/docs/dev/api/command-and-control/">Command &amp; Control API for AMQP</a>.
+With this API, clients send command messages to an Apache Kafka&reg; cluster instead of an AMQP Messaging Network.</p>
+
+<p>See <a href="/hono/docs/dev/api/kafka-api/">Kafka-based APIs</a> for fundamental information about Hono&rsquo;s Kafka-based APIs.
+The statements there apply to this specification.</p>

+    <div>The support of Kafka as a messaging system is currently a preview and not yet ready for production. The APIs are subject to change without prior notice.</div>

+<h2 id="send-a-one-way-command">Send a One-Way Command</h2>
+
+<p>Business Applications use this operation to send a command to a device for which they do not expect to receive a response from the device.
+For that, the Business Application connects to the <em>Kafka Cluster</em> and writes a message to the tenant-specific topic <code>hono.command.${tenant_id}</code> where <code>${tenant_id}</code> is the ID of the tenant that the client wants to send the command for.</p>
+
+<p><strong>Preconditions</strong></p>
+
+<ol>
+<li>Either the topic <code>hono.command.${tenant_id}</code> exists, or the broker is configured to automatically create topics on demand.</li>
+<li>The <em>Business Application</em> is authorized to write to the topic.</li>

+<li>The <em>Business Application</em> writes a command message to the topic <code>hono.command.${tenant_id}</code> on the <em>Kafka Cluster</em>.</li>
+<li>Hono consumes the message from the <em>Kafka Cluster</em> and forwards it to the device, provided that the target device is connected and is accepting commands.</li>
+</ol>
+
+<p><strong>Message Format</strong></p>
+
+<p>The key of the message MUST be the ID of the device that the command is targeted at.</p>
+
+<p>Metadata MUST be set as Kafka headers on a message.

+The Business Application can consume the corresponding command response from the <code>hono.command_response.${tenant_id}</code> topic.</p>
+
+<p>In contrast to a one-way command, a request/response command contains a <em>response-expected</em> header with value <code>true</code> and a <em>correlation-id</em> header, providing the identifier that is used to correlate a response message to the original request.</p>

 	"description": "",
-	"content": "The Event API is used by Protocol Adapters to send event messages downstream. Business Applications and other consumers use the API to receive messages published by devices belonging to a particular tenant.\nThe Event API is defined by means of AMQP 1.0 message exchanges, i.e. a client needs to connect to Hono using AMQP 1.0 in order to invoke operations of the API as described in the following sections. Throughout the remainder of this page we will simply use AMQP when referring to AMQP 1.0.\nSouthbound Operations The following operations can be used by Protocol Adapters to forward event messages received from devices to downstream consumers like Business Applications.\nForward Event Preconditions\n Adapter has established an AMQP connection with the AMQP Messaging Network. Adapter has established an AMQP link in role sender with the AMQP Messaging Network using target address event/${tenant_id} where ${tenant_id} is the ID of the tenant that the client wants to upload event messages for. The device for which the adapter wants to send an event has been registered (see Device Registration API).  Hono supports AT LEAST ONCE delivery of Event messages only. A client therefore MUST use unsettled for the snd-settle-mode and first for the rcv-settle-mode fields of its attach frame during link establishment. All other combinations are not supported by Hono and may result in the termination of the link or connection (depending on the configuration of the AMQP Messaging Network).\nThe AMQP messages used to forward events to the AMQP Messaging Network MUST have their durable property set to true. The AMQP Messaging Network is expected to write such messages to a persistent store before settling the transfer with the accepted outcome.\nMessage Flow\nThe following sequence diagram illustrates the flow of messages involved in the MQTT Adapter forwarding an event to the downstream AMQP Messaging Network.\n  Forward event flow    Device 4711 publishes an event using MQTT QoS 1.  MQTT Adapter transfers data to AMQP 1.0 Messaging Network. AMQP 1.0 Messaging Network acknowledges reception of the message. MQTT Adapter acknowledges the reception of the message to the Device.   When the AMQP Messaging Network fails to settle the transfer of an event message or settles the transfer with any other outcome than accepted, the protocol adapter MUST NOT try to re-send such rejected messages but MUST indicate the failed transfer to the device if the transport protocol provides means to do so.\nMessage Format\nSee Telemetry API for definition of message format.\nNorthbound Operations Receive Events Hono delivers messages containing events reported by a particular device in the same order that they have been received in (using the Forward Event operation).\nHono supports multiple non-competing Business Application consumers of event messages for a given tenant. Hono allows each Business Application to have multiple competing consumers for event messages for a given tenant to share the load of processing the messages.\nPreconditions\n Client has established an AMQP connection with Hono. Client has established an AMQP link in role receiver with Hono using source address event/${tenant_id} where ${tenant_id} represents the ID of the tenant the client wants to retrieve event messages for.  Hono supports AT LEAST ONCE delivery of Event messages only. A client therefore MUST use unsettled for the snd-settle-mode and first for the rcv-settle-mode fields of its attach frame during link establishment. All other combinations are not supported by Hono and result in the termination of the link.\nMessage Flow\nThe following sequence diagram illustrates the flow of messages involved in a Business Application receiving an event message from Hono.\n  Receive event data flow (success)    AMQP 1.0 Messaging Network delivers event message to Business Application.  Business Application acknowledges reception of message.   Message Format\nSee Telemetry API for definition of message format.\nWell-known Event Message Types Hono defines several well-known event types which have specific semantics. Events of these types are identified by means of the AMQP message\u0026rsquo;s content-type.\nEmpty Notification An AMQP message containing this type of event does not have any payload, so the body of the message MUST be empty.\nThe AMQP 1.0 properties an event sender needs to set for an empty notification event are defined in the Telemetry API.\nThe relevant properties are listed again in the following table:\n   Name Mandatory Location Type Description     content-type yes properties symbol MUST be set to application/vnd.eclipse-hono-empty-notification   ttd no application-properties int The time \u0026lsquo;til disconnect as described in the Telemetry API.    NB An empty notification can be used to indicate to a Business Application that a device is currently ready to receive an upstream message by setting the ttd property. Backend Applications may use this information to determine the time window during which the device will be able to receive a command.\nConnection Event Protocol Adapters may send this type of event to indicate that a connection with a device has been established or has ended. Note that such events can only be sent for authenticated devices, though, because an event is always scoped to a tenant and the tenant of a device is established as part of the authentication process.\nThe AMQP message for a connection event MUST contain the following properties in addition to the standard event properties:\n   Name Mandatory Location Type Description     content-type yes properties symbol Must be set to application/vnd.eclipse-hono-dc-notification+json   device_id yes application-properties string The ID of the authenticated device    Each connection event\u0026rsquo;s payload MUST contain a UTF-8 encoded string representation of a single JSON object with the following fields:\n   Name Mandatory Type Description     cause yes string The cause of the connection event. MUST be set to either connected or disconnected.   remote-id yes string An identifier of the device that is the subject of this event, e.g. an IP address:port, client id etc. The format and semantics of this identifier is specific to the protocol adapter and the transport protocol it supports.   source yes string The type name of the protocol adapter reporting the event, e.g. hono-mqtt.   data no object An arbitrary JSON object which may contain additional information about the occurrence of the event.    The example below might be used by the MQTT adapter to indicate that a connection with a device using client identifier mqtt-client-id-1 has been established:\n{ \u0026quot;cause\u0026quot;: \u0026quot;connected\u0026quot;, \u0026quot;remote-id\u0026quot;: \u0026quot;mqtt-client-id-1\u0026quot;, \u0026quot;source\u0026quot;: \u0026quot;hono-mqtt\u0026quot;, \u0026quot;data\u0026quot;: { \u0026quot;foo\u0026quot;: \u0026quot;bar\u0026quot; } }  Device Provisioning Notification Device registries may send this event to convey provisioning related changes regarding a device. This may be used as a hook for northbound applications if further application specific logic should be implemented upon provisioning changes.\nAn AMQP message containing this type of event does not have any payload, so the body of the message MUST be empty.\nThe relevant properties are listed again in the following table:\n   Name Mandatory Location Type Description     content-type yes properties symbol MUST be set to application/vnd.eclipse-device-provisioning-notification   hono_registration_status yes application-properties string Contains NEW if the device has been newly provisioned.   tenant_id yes application-properties string The tenant id denoting the tenant of the device.   device_id yes application-properties string The id of the device.   gateway_id no application-properties string This property contains a value only if the device\u0026rsquo;s registration status has been changed by a gateway acting on behalf of the device. In such a case, the property contains the identifier of the gateway, otherwise the property will not be included.   "

Backend Applications may use this information to determine the time window during which the device will be able to receive a command.\nConnection Event Protocol Adapters may send this type of event to indicate that a connection with a device has been established or has ended. Note that such events can only be sent for authenticated devices, though, because an event is always scoped to a tenant and the tenant of a device is established as part of the authentication process.\nThe AMQP message for a connection event MUST contain the following properties in addition to the standard event properties:\n   Name Mandatory Location Type Description     content-type yes properties symbol Must be set to application/vnd.eclipse-hono-dc-notification+json   device_id yes application-properties string The ID of the authenticated device    Each connection event\u0026rsquo;s payload MUST contain a UTF-8 encoded string representation of a single JSON object with the following fields:\n   Name Mandatory Type Description     cause yes string The cause of the connection event. MUST be set to either connected or disconnected.   remote-id yes string An identifier of the device that is the subject of this event, e.g. an IP address:port, client id etc. The format and semantics of this identifier is specific to the protocol adapter and the transport protocol it supports.   source yes string The type name of the protocol adapter reporting the event, e.g. hono-mqtt.   data no object An arbitrary JSON object which may contain additional information about the occurrence of the event.    The example below might be used by the MQTT adapter to indicate that a connection with a device using client identifier mqtt-client-id-1 has been established:\n{ \u0026quot;cause\u0026quot;: \u0026quot;connected\u0026quot;, \u0026quot;remote-id\u0026quot;: \u0026quot;mqtt-client-id-1\u0026quot;, \u0026quot;source\u0026quot;: \u0026quot;hono-mqtt\u0026quot;, \u0026quot;data\u0026quot;: { \u0026quot;foo\u0026quot;: \u0026quot;bar\u0026quot; } }  Device Provisioning Notification Device registries may send this event to convey provisioning related changes regarding a device. This may be used as a hook for northbound applications if further application specific logic should be implemented upon provisioning changes.\nAn AMQP message containing this type of event does not have any payload, so the body of the message MUST be empty.\nThe relevant properties are listed again in the following table:\n   Name Mandatory Location Type Description     content-type yes properties symbol MUST be set to application/vnd.eclipse-hono-device-provisioning-notification   hono_registration_status yes application-properties string Contains NEW if the device has been newly provisioned.   tenant_id yes application-properties string The tenant id denoting the tenant of the device.   device_id yes application-properties string The id of the device.   gateway_id no application-properties string This property contains a value only if the device\u0026rsquo;s registration status has been changed by a gateway acting on behalf of the device. In such a case, the property contains the identifier of the gateway, otherwise the property will not be included.   "

 	"content": " The Event API is used by Protocol Adapters to send event messages downstream. Business Applications and other consumers use the API to receive messages published by devices belonging to a particular tenant.\nThe Event API for Kafka is an alternative to the Event API for AMQP. With this API clients publish event messages to an Apache Kafka\u0026reg; cluster instead of an AMQP Messaging Network.\nSee Kafka-based APIs for fundamental information about Hono\u0026rsquo;s Kafka-based APIs. The statements there apply to this specification.\n Tech preview The support of Kafka as a messaging system is currently a preview and not yet ready for production. The APIs are subject to change without prior notice.  Southbound Operations The following operation can be used by Protocol Adapters to send event messages received from devices to downstream consumers like Business Applications.\nProduce Event The protocol adapter writes messages to the tenant-specific topic hono.event.${tenant_id} where ${tenant_id} is the ID of the tenant that the client wants to upload event messages for.\nPreconditions\n Either the topic hono.event.${tenant_id} exists, or the broker is configured to automatically create topics on demand. The client is authorized to write to the topic. The device for which the adapter wants to send event messages has been registered (see Device Registration API).  Message Flow\nHono supports AT LEAST ONCE delivery of Event messages only, as defined in Telemetry API for Kafka.\nThe following sequence diagram illustrates the flow of messages involved in the MQTT Adapter producing an event to the Kafka cluster.\n  Produce event flow    Device 4711 publishes an event using MQTT QoS 1.  MQTT Adapter produces an event message to Kafka Cluster. Kafka cluster acknowledges reception of the message. MQTT Adapter acknowledges the reception of the message to the Device.   When a Kafka producer raises an exception while sending an event message to Kafka, the protocol adapter MUST NOT try to re-send such rejected messages but MUST indicate the failed transfer to the device if the transport protocol provides means to do so.\nMessage Format\nSee Telemetry API for Kafka for the definition of the message format.\nNorthbound Operations The following operation can be used by Business Applications to receive event messages from Kafka.\nConsume Events Hono delivers messages containing events reported by a particular device in the same order that they have been received in (using the Produce Event operation). Business Applications consume messages from the tenant-specific topic hono.event.${tenant_id} where ${tenant_id} represents the ID of the tenant the client wants to retrieve event messages for.\nPreconditions\n Either the topic hono.event.${tenant_id} exists, or the broker is configured to automatically create topics on demand. The client is authorized to read from the topic. The client subscribes to the topic with a Kafka consumer.  Hono supports AT LEAST ONCE delivery of Event messages only. A consumer is expected to provide proper AT LEAST ONCE semantics and therefore MUST NOT commit offsets of messages that have not yet been fully processed.\nMessage Flow\nThe following sequence diagram illustrates the flow of messages involved in a Business Application consuming an event message from the Kafka cluster.\n  Consume event flow (success)    Business Application polls event messages from Kafka Cluster.  Kafka Cluster returns a batch of messages.  Business Application processes the messages. Business Application commits the offset of the last processed event message.  Kafka Cluster acknowledges the commit.   Message Format\nSee Telemetry API for Kafka for the definition of the message format.\nWell-known Event Message Types Hono defines several well-known event types which have specific semantics.

+	"content": "The Command \u0026amp; Control API of Eclipse Hono\u0026trade; is used by Business Applications to send commands to connected devices.\nCommands can be used to trigger actions on devices. Examples include updating a configuration property, installing a software component or switching the state of an actuator.\nHono distinguishes two types of commands. The first type is one-way only. In this case the sender of the command does not expect the device to send back a message in response to the command. This type of command is referred to as a one-way command in the remainder of this page. One-way commands may be used to e.g. notify a device about a change of state.\nThe second type of commands expects a response to be sent back from the device as a result of processing the command. In this case the response contains a status code which indicates whether the command could be processed successfully. If so, the response may also include data representing the result of processing the command. This type of command is plainly referred to as a command because it represents the default case.\nThe Command \u0026amp; Control API for Kafka is an alternative to the Command \u0026amp; Control API for AMQP. With this API, clients send command messages to an Apache Kafka\u0026reg; cluster instead of an AMQP Messaging Network.\nSee Kafka-based APIs for fundamental information about Hono\u0026rsquo;s Kafka-based APIs. The statements there apply to this specification.\n Tech preview The support of Kafka as a messaging system is currently a preview and not yet ready for production. The APIs are subject to change without prior notice.  Send a One-Way Command Business Applications use this operation to send a command to a device for which they do not expect to receive a response from the device. For that, the Business Application connects to the Kafka Cluster and writes a message to the tenant-specific topic hono.command.${tenant_id} where ${tenant_id} is the ID of the tenant that the client wants to send the command for.\nPreconditions\n Either the topic hono.command.${tenant_id} exists, or the broker is configured to automatically create topics on demand. The Business Application is authorized to write to the topic.  Message Flow\n The Business Application writes a command message to the topic hono.command.${tenant_id} on the Kafka Cluster. Hono consumes the message from the Kafka Cluster and forwards it to the device, provided that the target device is connected and is accepting commands.  Message Format\nThe key of the message MUST be the ID of the device that the command is targeted at.\nMetadata MUST be set as Kafka headers on a message. The following table provides an overview of the headers the Business Application needs to set on a one-way command message.\n   Name Mandatory Type Description     device_id yes string The identifier of the device that the command is targeted at.   subject yes string The name of the command to be executed by the device.   content-type no string If present, MUST contain a Media Type as defined by RFC 2046 which describes the semantics and format of the command\u0026rsquo;s input data contained in the message payload. However, not all protocol adapters will support this property as not all transport protocols provide means to convey this information, e.g. MQTT 3.1.1 has no notion of message headers.    The command message MAY contain arbitrary payload, set as message value, to be sent to the device. The value of the message\u0026rsquo;s subject header may provide a hint to the device regarding the format, encoding and semantics of the payload data.\nSend a (Request/Response) Command Business Applications use this operation to send a command to a device for which they expect the device to send back a response. For that, the Business Application connects to the Kafka Cluster and writes a message to the tenant-specific topic hono.command.${tenant_id} where ${tenant_id} is the ID of the tenant that the client wants to send the command for. The Business Application can consume the corresponding command response from the hono.command_response.${tenant_id} topic.\nIn contrast to a one-way command, a request/response command contains a response-expected header with value true and a correlation-id header, providing the identifier that is used to correlate a response message to the original request.\nPreconditions\n Either the topics hono.command.${tenant_id} and hono.command_response.${tenant_id} exist, or the broker is configured to automatically create topics on demand. The Business Application is authorized to write to the hono.command.${tenant_id} topic and read from the hono.command_response.${tenant_id} topic. The Business Application is subscribed to the hono.command_response.${tenant_id} topic with a Kafka consumer.  Message Flow\n The Business Application writes a command message to the topic hono.command.${tenant_id} on the Kafka Cluster. Hono consumes the message from the Kafka Cluster and forwards it to the device, provided that the target device is connected and is accepting commands. The device sends a command response message. Hono writes that message to the hono.command_response.${tenant_id} topic on the Kafka Cluster. The Business Application consumes the command response message from the hono.command_response.${tenant_id} topic.  Command Message Format\nThe key of the message MUST be the ID of the device that the command is targeted at.\nMetadata MUST be set as Kafka headers on a message. The following table provides an overview of the headers the Business Application needs to set on a request/response command message.\n   Name Mandatory Type Description     correlation-id yes string The identifier used to correlate a response message to the original request. It is used as the correlation-id header in the response.   device_id yes string The identifier of the device that the command is targeted at.   response-expected yes boolean MUST be set with a value of true, meaning that a response from the device is expected for the command.   subject yes string The name of the command to be executed by the device.   content-type no string If present, MUST contain a Media Type as defined by RFC 2046 which describes the semantics and format of the command\u0026rsquo;s input data contained in the message payload. However, not all protocol adapters will support this property as not all transport protocols provide means to convey this information, e.g. MQTT 3.1.1 has no notion of message headers.    The command message MAY contain arbitrary payload, set as message value, to be sent to the device. The value of the message\u0026rsquo;s subject header may provide a hint to the device regarding the format, encoding and semantics of the payload data.\nAn application can determine the overall outcome of the operation by means of the response to the command that is sent back by the device. An application should consider execution of a command to have failed, if it does not receive a response within a reasonable amount of time.\nResponse Message Format\nThe key of the message MUST be the ID of the device that the command response is from.\nMetadata MUST be set as Kafka headers on a message. The following table provides an overview of the headers set on a message sent in response to a command.\n   Name Mandatory Type Description     correlation-id yes string MUST contain the value of the correlation-id header of the request message that this is the response for.   device_id yes string The identifier of the device that sent the response.   status yes integer MUST indicate the status of the execution. See table below for possible values.   content-type no string If present, MUST contain a Media Type as defined by RFC 2046 which describes the semantics and format of the command\u0026rsquo;s input data contained in the message payload. However, not all protocol adapters will support this property as not all transport protocols provide means to convey this information, e.g. MQTT 3.1.1 has no notion of message headers.    The status header must contain an HTTP 1.1 response status code:\n   Code Description     2xx The command has been processed successfully.   4xx The command could not be processed due to a client error, e.g. malformed message payload.   5xx The command could not be processed due to an internal problem at the device side.    The semantics of the individual codes are specific to the device and command. For status codes indicating an error (codes in the 400 - 599 range) the message body MAY contain a detailed description of the error that occurred.\nThe command response message MAY contain arbitrary payload, set as message value, to be sent to the business application.\n"
