Mqtt commands by change

I started to play with Homey MQTT Hub, and it seems very promising :slight_smile:
It is possible to setup also the topic in the way, that the message is sent only by change? f.e. temperature, activation of motion sensor, switch on/off the light etc etc?

If there is a particular reason for not asking this in one of the excisting MQTT hub topics then i leave it open. Please let me know.

@Marian Messages are sent on startup and at capability state changes.
