I just got a ZBT-2 and the setup was genuinely flawless. I'm really happy with how it went. Migrating from the ZBT-1 took a couple of minutes and just worked straight away.
Does the ZBT-2 need to stay connected to the Server Running Home Assistant or can I locate it further away? (optimal location would be in the middle floor of my house but my NAS is on the ground floor near the front). I remember seeing people speaking about this functionality but I don't see anything on the product page.
Cheers!
