Hello,
I’ve set up 3 E1 with temperature input from a single centrally placed w100.
It works good but I’m unable to set the target heating temperature from the W100. Only in the app. I’ve made the 3 E1’s in to a device group but I still can’t seem to make it work. Anyone know a solution to this?
Hi @kboretti - I think nobody can help you here - the W600 isn’t released yet and still in beta!
So there are only some beta Testers who got one w600 for testing! Just more wondering how you got 3 W600 already 
Hello, W500 analog. Check out my cheat sheet. For information to users, the capabilities of the W500
The W100 while can be used for temperature detection for all three of your E1 TRV Valves it cannot control all three for setting the target temperatures.
I am a beta tester for the new W600 Value and currently it’s the same situation but the Aqara developers have said this functionality will be implemented at some point.
Thank you for clearing that up. Hopefully 3 E1’s in a group could also be exposed to HomeKit as a single entity. Instead of 3 different devices.
I’m controlling underfloor heating and I have a few rooms with 3 lines and therefore 3 valves in them requiring 3 E1’s.
