I had to choose between the X60 model v2 and the v3 because I preferably did not want to use both in one setting.

Since I did not find any comparison on the internet, I wanted to share mine. Apart from the different firmwares I found:

V2 supports HomeCare (free) - runs on 2.0A

V3 supports HomeShield (partly fee) - runs on 1,5A

Hope you find it helpful and please add your experiences.

I finally choose to keep the V2, mainly because of the free HomeCare service
