Until now, I've been using a very old method to get my Zigbee setup working: I use Zigbee2MQTT as the coordinator, a Mosquitto broker, and a Domoticz plugin (Zigbee2MQTT) that hasn’t been supported for quite some time.
I've set up a test platform identical to my current one, and I installed the "ZigbeeForDomoticz" plugin on it — and it seems to be working really well!
My question is: this plugin doesn't seem to use MQTT, right?
I stopped and disabled the Mosquitto service, and everything still works perfectly (which gave me a nice CPU load reduction!
So, does that mean the MQTT broker is now completely useless for me?
