Is the Cold Weather setting avaiable to all (I mean, also for those with an OT relay, not a basic BDR91 ?)
I think I don't have it on my settings screen.

Also, as for the other features I would love to see:
On the System Summary, I think having the list of devices linked to the room would be usefull.
Right now, it is impossible to know how many HR or Thermostats are linked to a room. This makes troubleshooting the installation a bit complex.
