Good morning all 
did make a device handler for this one tonight,
You’ll find it on my git HERE
Just putting it to test myself now, at 4 AM in the morning 
I dont expect it to work straight away since im halfway asleep doing this, but seems to work at this point.
Please try it out 
good night…
EDIT:
It’s really bedtime now, managed to put this in the wrong section off the community,
Posted it here instead: Fibaro FGS-212 Relay, Device
