HeatIt DIN 616 does not respond anymore after new firmware 7.0.0 on Homey

Since the upgrade to 7.0.0 on my Homey, the HeatIt DIN 616 does not seem to respond anymore.
I’m not receiving any error messages in the app, there it looks like everytinh is working fine.

It seems that a lot of users have problems with Z-Wave devices after updating to v7.0.0.
