[OpenTRV-dev] Radiator debugging and re-calibration

[Bo Herrmannsen]

" automatically re-calibrate the first time heat is required after a long
period of inactivity"

i switched to the conrad wall thingy as i had the window sensor laying
arround anyway. they do open and close fully once a week to make sure they
valve part in the pipe works does not get stuck

even if i turn the wall unit in to off mode it will do this.

since all windows and doors was replaced by land lord in the beginning of
year i have yet to see any activity.

but the first step will be to see if opentrv and conrad agrees's on the %
open

should connection between the 2 be lost conrad will open to 30% after an
hour
