@foggy gyro There are three Zigbee options with Home Assistant (regardless of how you install it). These are:
deCONZ is relatively stable and mature with its own UI (and Discord server). It can run in an add-on, in a Docker container, or natively. Only the ConBee range of sticks and RaspBee GPIO boards are support. Known working devices are documented, and how to request support for a new device is documented too (you can't add unsupported devices yourself).
zha is actively developed as part of Home Assistant Core, using the zigpy stack, the UI also being part of Home Assistant. The EmberZNet based sticks are recommended, but there are other options. There is no list of supported devices, as any standards compliant device should work. Devices that require extra support are listed, and adding unsupported devices is documented (you can't add unsupported devices yourself).
Zigbee2MQTT is very actively developed and can run in an add-on, in a Docker container, and natively. As of 1.15 has a native UI, and it also uses MQTT for control and configuration. It supports mostly TI based sticks, with the Zig-Ah-Zig-Ah! and Slaesh's sticks being recommended. The known working devices are well documented (which usually includes how to pair them so you don't have to find the manual), and adding unsupported devices is also documented.
