[feature] Set button labels via MQTT about homebuttons HOT 2 CLOSED

This worked perfectly, thanks! I wrote up some documentation about testing directly with MQTT and will submit a pull request so it can be added to the official repo if it looks acceptable.

This is already supported. The device wakes up every N minutes (configurable) to publish sensor states and check for new commands.

You are missing a retain flag in your publish command. Try this:

mosquitto_pub -h 192.168.0.109 -p 1883 -t "homebuttons/Home buttons/cmd/btn_6_label" -m "PARTY" -r

The device cannot receive messages when sleeping. The retain flag makes the MQTT broker store the message and send it to device when it reconnects.
