Allow changing temperature if one device in a group of two or more loses connectivity
I initially reported this as a bug to online support, then they told me it works by design and should bring it up here instead. Which doesn't make sense to me but still, they didn't leave me with any options.
It appears that if one device in a group is offline, you can't control any of the remaining ones through the UI. Instead the entire room shows up as "no remote access". Which doesn't make sense to me. In my case
1) I have a room with one temperature sensor and three SRTs
2) when one SRT drops offline (per the screenshot below) it's only reasonable I should still be able to control the room. sure enough, one SRT is offline, but no reason this should affect the temp sensor and the two other SRTs. Being able to get 66% of heat is better than zero heat
Couple of screenshots follow to illustrate my point.
