Has anyone been able to make HA work with ISY V5?
I have looked all over this forum and UDI and have only found 1 person give up on it.
Yea, I just upgraded to V5 and I am in the same boat… 
Which version are you on?
5.0.10 broke Home Assistant support because of a completely bizarre change to their REST API. I am working on a fix for Hass 0.61.
