Their ceiling light (T1M) works but you lose some functionality - basically can’t use animations for the ring light. Besides that it’s been solid for me.

Just updated this morning. Fortunately, the only issue I had was needing to add the “adapter: zstack” to the configuration of my z2m addon.

Fortunately everything appears to be very well documented on how to troubleshoot most issues but I’m sure people with older installations with lots of legacy code will struggle more (my zone deployment is only 1 year old for reference).
