I have the following Thing configuration: Bridge mqtt:broker:mosquitto "MQTT Broker" [ host="<redacted>", port=32038, clientID="openhab" ] { Thing topic fireplace "Fireplace" @ "Living Room" { Channels: Type switch : power "Power" [ stateTopic…

[image] rossko57: These are string params e.g. on=“1” I get the same warning whether I specify these as strings or numbers

[image] H102: You can try with the MAP transformation. Any ideas how this would work in conjunction with JSONPath? I need the JSONPath transformation in order to extract just the power field; other fields may be present and will not be static, so I can’t hard-code them in a Map.

[image] ssmall: I get the same warning whether I specify these as strings or numbers Sure. But one way is correct and ought to work, one way is not and will never work. You’re not the only one struggling with this feature, maybe it is broken in some versions - what version is involved here? …

Maybe a bit OFFTOPIC but does your device react on the posted commands via openHAB? You don’t have a commandTopic in your setup!

I think (from other similar posts) the word ‘command’ is a bit misleading in the binding’s message, and should be interpreted more like ‘payload’

To my present understanding(!) stateTopics were to be received by MQTT Things, commandTopics are to be sent. :thinking:

If I think I’ve screwed up on the topic or payload type for mqtt, I run it through mqttfx where it’s easy to change both the topic and payload to see where I’ve gone wrong.

Yes. What I’m saying is that the OPs error message is produced in response to processing an incoming topic, just as he as configured, and the word ‘command’ in the error message refers in this case to the incoming payload and is a misnomer in openHABs usual terms. There is no openHAB command invol…

:+1: My question is standing, does the device react at all when the openHAB switch is triggered? In my understanding that warning is caused by a state message sent by the device, which COULD have been triggered by…?

[image] ssmall: {“power”:1} uhh, the device sends that. It doesn’t matter why, all the poor fellow wants to do is turn that into ON

You’d be interested in REGEX with JSONPATH

(REGEX is an installable add-on as well)

not sure if you mean channel trigger option?
