This block will publish the provided message on the provided topic via the specified broker, which you can select in a popup by clicking inside the thing block. Only choose a MQTT broker when picking the thing.
You can optionally retain the message on the broker.

Sorry can you give some brainstorming for what this could be more efficient than creating a generic MQTT Item with sam cmnd topics?

The only think I can image is to upload a bunch of firmware to all groupTopics. But in this cases I am not good enough in MQTT to say where the binary is coming from :wink:

this block has the same problem that is telegram actions

Is there also a “subscribe MQTT message” block?

5

No, you have to create a Generic MQTT Thing with a Channel to subscribe to messages.

It makes no sense to subscribe to a topic in a rule so the MQTT binding doesn’t implement such an action.

6

Ahhh, this is for the blocky language. I was wondering all along what this is. It should say so in the addon store. It has the same icon as the mqtt binding too.

7

It is in the Block Library category. Everything posted in Add-on Marketplace → Block Libraries is for Blockly. In MainUI → Add-on Store ->Automation, everything under the “Block Libraries” is for Blockly.
