Thanks Edwin, yes I have been trying to find out how best to control them, and am using Markus Klinger’s Heating Scheduler app, with flows to call for heat via Fibaro relays and “disable” the schedule (which I think means turn off the heating, rather than simply abandon the schedule, but am waiting for clarification) if the windows are opened…
(I understand the VThermo app is supposed to do this without flows, but it is not working for me)
I can’t see any discernible pattern for why some drain faster than others, and why they all drain much faster than the predicted. The battery reporting is poor and inconsistent, and generally the indication of battery failure comes from one of the occupants moaning that the radiators are “boiling” when the batteries fail and the valves are fully opened.
