[OpenTRV-dev] Radiator debugging and re-calibration

[Bruno Girin]

Hi all,

As it's been getting colder recently, my OpenTRV devices have started
occasionally firing up the heating, all well and good. However, one of the
OpenTRV equipped radiators (rev 1 + Conrad actuator) stays stone cold
despite the valve claiming to be open at 60+. All other OpenTRV equipped
radiators are fine.

So the question is: how do you identify the root cause and fix for such a
problem? Could it be due to the valve having somehow been de-calibrated
during the summer while it wasn't in use?

As far as OpenTRV is concerned, there are a couple of things that we could
do:
- add something in a FAQ to explain how to analyse such problems
- automatically re-calibrate the first time heat is required after a long
period of inactivity or do so regularly (of course assuming the root cause
is a calibration one)

Thoughts?

Bruno
