    This adapter uses Sentry libraries to automatically report exceptions and code errors to the developers. For more details and for information how to disable the error reporting see Sentry-Plugin Documentation! Sentry reporting is used starting with js-controller 3.0.

    MQ Telemetry Transport for ioBroker (MQTT).

    MQTT (formerly Message Queue Telemetry Transport) is a publish-subscribe based "light weight" messaging protocol for use on top of the TCP/IP protocol. It is designed for connections with remote locations where a "small code footprint" is required and/or network bandwidth is limited. The Publish-Subscribe messaging pattern requires a message broker. The broker is responsible for distributing messages to interested clients based on the topic of a message. Historically, the 'MQ' in 'MQTT' came from IBM's MQ message queuing product line.

    This adapter uses the MQTT.js library from https://github.com/adamvr/MQTT.js/

    Configuration

    • Type - Select "Client" (If you want to receive and send messages to other broker) or "Server" if you want to create own MQTT broker.

    Server settings

    • WebSockets - if parallel to TCP Server, the WebSocket MQTT Server should run.
    • Port - Port where the server will run (Default 1883). WebSockets will always run on port+1 (Default 1884)
    • SSL - If TCP and WebSockets should run as secure server.
    • Authentication/Username - If authentication required, you can specify the username. It is suggested to always use SSL with authentication to not send passwords over unsecure connection.
    • Authentication/Password - Password for user.
    • Mask to publish own states - Pattern to filter ioBroker states, which will be sent to clients. You can use wildcards to specify group of messages, e.g ".memRss, mqtt.0.` to get all memory states of all adapters and all states of adapter mqtt.0
    • Publish only on change - New messages will be sent to client only if the state value changes. Every message sent by the client will be accepted, even if the value does not change.
    • Publish own states on connect - by every client connection the all known states will be sent to client (defined by the state mask), to tell him which states has the ioBroker.
    • Prefix for all topics - if set, every sent topic will be prepended with this prefix, e.g. if prefix iobroker/ all states will have names like **iobroker**/mqtt/0/connected
    • Trace output for every message - Debug outputs.
    • Send states (ack=true) too - Normally only the states/commands with ack=false will be sent to partner. If this flag is set every state independent of ack will be sent to partner.
    • Use different topic names for set and get - if active, so every state will have two topics: adapter/instance/stateName and adapter/instance/stateName/set. In this case topic with /set will be used to send non acknowledged commands (ack: false) and topic without /set to receive state updates (with ack: true). The client will receive sent messages back in this mode.
    • Interval before send topics by connection - Pause between connection and when all topics will be sent to client (if activated).
    • Send interval - Interval between packets by sending all topics (if activated). Used only by once after the connection establishment.
    • Force clean session - Overwrite the client settings and clear or keep session.
    • Publish messages without "retain" flag - Send messages to other clients without retain flag (read more in next paragraph)

    The ioBroker MQTT-Broker in server mode only simulates the behaviour of real MQTT-Broker (like Mosquitto), but it is not the same. Real MQTT-Broker normally does not save the values of the topics and just forwards the message to other subscribed clients.

    To force real MQTT-Broker to behave like ioBroker MQTT-Broker all messages must be sent with "retain" flag. In this case the values will be stored too.

    ioBroker MQTT-Broker saves always the values into the States-DB, so it can be processed by other adapters. Because of that the messages are always published with retain flag.

    If your client has problems with retained messages you can force ioBroker MQTT-Broker to send messages without retain flag with Publish messages without "retain" flag option. In this case the messages will be stored in States-DB anyway.

    If the option Send states (ack=true) too is not activated, so you can clear the value of the topic (state) with ack=true and the update will not bes sent to subscribed clients. And when the client connects next time it will not get the last command again.

    The JS-Code should look like this:

    await setStateAsync('mqtt.0.valetudo.vale.BasicControlCapability.operation.set', 'cleanStart'); // ack=false
    await setStateAsync('mqtt.0.valetudo.vale.BasicControlCapability.operation.set', '', true); // ack=true to clear the command
    

    Client settings

    • URL - name or ip address of the broker/server. Like localhost.
    • Port - Port of the MQTT broker. By default, 1883
    • Secure - If secure (SSL) connection must be used.
    • User - if broker required authentication, define here the username.
    • Password - if the username is not empty the password must be set. It can be empty.
    • Password confirmation - repeat here the password.
    • Subscribe Patterns - Subscribe by the pattern. See chapter "Examples of using wildcards" to define the pattern. '#' to subscribe for all topics. 'mqtt/0/#,javascript/#' to subscribe for states of mqtt.0 and javascript
    • Publish only on change - Store incoming messages only if payload differs from actual stored.
    • Mask to publish own states - Mask for states, that must be published to broker. '' - to publish all states. 'io.yr.,io.hm-rpc.0.*' to publish states of yr and hm-rpc adapter.
    • Publish all states at start - Publish all states (defined by the state mask) every time by connection establishment to announce own available states and their values.
    • Prefix for topics - The prefix can be defined for own states. Like /var/ioBroker/. Name of topics will be for example published with the name /var/ioBroker/ping/192-168-1-5.
    • Test connection - Press the button to check the connection to broker. Adapter must be enabled before.
    • Send states (ack=true) too - Normally only the states/commands with ack=false will be sent to partner. If this flag is set every state independent of ack will be sent to partner.
    • Use different topic names for set and get - if active, so every state will have two topics: adapter/instance/stateName and adapter/instance/stateName/set. In this case topic with /set will be used to send non acknowledged commands (ack: false) and topic without /set to receive state updates (with ack: true).
    • Send state object as mqtt message - The client sends the states as parsed string JSON objects to the broker (example parsed string JSON object: {"val":true,"ack":true,"ts":1584690242021,"q":0,"from":"system.adapter.deconz.0","user":"system.user.admin","lc":1584624242021,"expire":true}); if not the values states.val is sent as a single value (example state.val as single value: true)
    • Persistent Session - When checked the broker saves the session information of the adapter. This means it tracks which messages have been sent/received by the adapter (only QoS Level 1 and 2) and to which topics the adapter has subscribed. This information survives a disconnect and reconnect of the adapter.

    Usage

    How to test mqtt client:

    • Set type to Client.
    • Leave port on 1883.
    • Set URL as broker.mqttdashboard.com
    • To get absolutely all topics(messages) set pattern to #.
    • To receive all topics for /4MS set pattern to /4MS/#
    • To receive all topics for /MS and /floorish set pattern to /4MS/#, /floorish/#

    Sending messages

    You may send / publish messages on topics using sendTo method from your adapter via MQTT adapter, e.g.:

    /*
     * @param {string}  MQTT instance     Specify MQTT instance to send message through (may be either server or client)
     * @param {string}  action            Action to use (always 'sendMessage2Client' for sending plain messages)
     * @param {object}  payload         
     * @param {string}  payload.topic     Topic to publish message on
     * @param {string}  payload.message   Message to be published on specified topic
     *
     */
    adapter.sendTo('mqtt.0', 'sendMessage2Client', {topic: '/your/topic/here', message: 'your message'});
    

    Examples of using wildcards

    The following examples on the use of wildcards, builds on the example provided in topic strings.

    • Sport
    • Sport/Tennis
    • Sport/Basketball
    • Sport/Swimming
    • Sport/Tennis/Finals
    • Sport/Basketball/Finals
    • Sport/Swimming/Finals

    If you want to subscribe to all Tennis topics, you can use the number sign '#', or the plus sign '+'.

    • Sport/Tennis/# (this will receive Sport/Tennis and Sport/Tennis/Finals)
    • Sport/Tennis/+ (this will receive Sport/Tennis/Finals but not Sport/Tennis)

    For JMS topics, if you want to subscribe to all Finals topics, you can use the number sign '#', or the plus sign '+'.

    • Sport/#/Finals
    • Sport/+/Finals

    For MQTT topics, if you want to subscribe to all Finals topics, you can use the plus sign '+' .

    Sport/+/Finals

    Binary messages

    With version 4.x there is a possibility to send and receive binary messages. Send works only with js-controller@4.2 or newer.

    You can change manually the common.type of existing objects to file and they will be processed as binary states.

    Or you can set the options All new topics will be processed as binary* in the instance settings to force all new topics will have automatically common.type="file".

    Tests

    The broker was tested with following clients:

    Todo

    • Implement resend of QoS 2 messages after a while. Whenever a packet gets lost on the way, the sender is responsible for resending the last message after a reasonable amount of time. This is true when the sender is a MQTT client and also when a MQTT broker sends a message.

    • queue packets with QoS 1/2 for the offline clients with the persistent session. Read here
