Thank you for your response, do you know if all ZigBee devices I currently have set up with my Dongle are likely to be compatible to MQTT? Thinking I’ll just move them all over
If you mean “Will all devices supported in ZHA also be supported in Z2M?”, definitely yes.
You will have to re-pair all your devices, though. There is an unsupported “migration” path, but which only half-works, anyway (as I experienced), so not worth to try.
EDIT: for reference, the Z2M thread discussing migration
