MQTT client module, to communicate with a MQTT server. The MQTT protocol can be used to retrieve values of sensors on a distant server. See MQTT for more info.
Address of the MQTT server.
Port used for the communication with the server.
Client identifier used for the communication.
User name of the client, if needed.
Password of the client, if needed.
Try to connect the client to the server. See auto connect at startup and auto reconnect parameters bellow.
Try to disconnect the client to the server.
Sends 1 value when the client is connected to the server.
Keep alive ensures that the connection between the broker and client is still open and that the broker and the client are aware of being connected.
Determines the ability for the client to reconnect automatically on connection failure.
Connect the client to the server immediately after the module is loaded.
On connection, a client sets the "clean session" flag, which is sometimes also known as the "clean start" flag. If clean session is set to false, then the connection is treated as durable. This means that when the client disconnects, any subscriptions it has will remain and any subsequent QoS 1 or 2 messages will be stored until it connects again in the future. If clean session is true, then all subscriptions will be removed for the client when it disconnects.
Traces all incoming data's in the trace-panel.
Topic to publish, as a an ascii string.
Payload for the topic as an ascii string, generally a json.
Quality of Service (QoS) level. It is an agreement between the sender of a message and the receiver of a message that defines the guarantee of delivery for a specific message. See QoS.
There are 3 QoS levels in MQTT:
A retained message is a normal MQTT message with the retained flag set to true. The broker stores the last retained message and the corresponding QoS for that topic. See retain.
Publishes all the topics.
List of all topics to subscribe as a comma-text. ie. "dev/#","sensor/+/temperature"
.
Clears all the subscriptions outputs.
Sends 1 value when a topic is received.
Topic received as a string.
Payload received as a string, generally a json.
Payload received as an array of bytes (ascii chars).
Sends 1 value when a any of the topics is received.
All topics received as a string.
All payloads received as a string, generally a json.
All payloads received as an array of bytes (ascii chars).
