Relay with MQTT commands issue

You are absolutely right, that’s why I was asking for help.

Could you be a bit more precise in how to do it? It would be nice and I could learn from that …
Many thanks!

My point was that after all the help you’ve received, you continue to operate in a manner that shows little benefit from it. For example, your self-certified “solution” (restructuring the topic) is just a happy accident and not a recommended course of action for others; it’s a misleading solution.

MQTT Discovery is enabled by SetOption19.

Thanks for the help!
