Home Assistant Green & Zigbee connectivity / usage

Aboulenain

I am a little further down the ha road but no expert however, let me see if I can explain a little from my limited experience.

Any compatible Zigbee hardware should simply work with the appropriate Zigbee dongle. Here is a list of devices that are known to be compatible with various dongles: Database of Zigbee devices compatible with ZHA, Tasmota, Zigbee2MQTT, deCONZ, ZiGate and ioBroker

Some Zigbee devices are also repeaters (ie they will pass on Zigbee messages). To improve you Zigbee mesh add some repeaters: Zigbee range and how to improve

Personally in my small flat I use HA Green with ZHA and a few repeaters and have found it very reliable.
