I come from Deconz and it worked satisfactorily for 7 years (raspbee1+2+conbee3).
The fact that new devices weren’t supported right from the start was never a big problem. But then I wanted to streamline my setup a bit and, after much deliberation, switched to ZHA, with ZBT-2 to be added later.
Three months have now passed. It runs just as stably as Deconz. Very good! But the way the devices are supported is terrible. Especially when it comes to something as essential as lights. In my case, Hue Bulbs.

Color loop: just on/off, no further settings. DIY

Flash light: Lights do not retain their previous state. DIY
-
Dimming lights with buttons: Forget it! Build something! DIY! No problem, but how do you stop a transition? Search the annals of GitHub - done
There’s more, but it’s not that important. So far, I’ve managed to get everything the way I wanted it, but in the long run, I don’t know what else is in store for me. I know you can do everything yourself, but why replicate native functions? For me, ZHA is nothing more than a good starting point when you start with HomeAssistant. I’m going to switch back to Deconz or maybe even Z2M.
After experiencing that very trivial things don’t work out of the box, I don’t believe that HomeAssistant or NabuCasa are serious about the ZBT-2. Maybe they should focus more on the basics than on gimmicks like voice, AI, and dashboards.
