Hi
It been some years since I upgraded my Ultra II and I purchased ETH03 in order to integrate with HA

Comfort II Ultra
Version 7.192
File system 34
UCM Type 10 - new
version 8.007 - new

HA is recomending UCM version >7.2xx

Latest available v7 7.215 v8 8.030

Is version 8.xxx requiring new HW? Is 7.215 latest then?

Always use the latest as it has additional fixes since 7.215 was tested against the HA integration. 8.030 has no known issues with HA.

Just to be sure because I did not followed latest HW versions and got some contradicting sugestions on AI

Is it OK to use 8.x FW for my Ultra II hardware?
