Follow up question please.
how do you ensure the batteries last long time? How long should you expect... any advice to maximise the life ??
Many thanks in advance.
@Djames I started with tado some 15 months ago and recently changed batteries in 2 radiators - others still going strong. I am convinced that the ease (or not) with which the device can move the 'pin' makes some difference - some people talk of only months between changes. Can't think of an magic answers!!
Once heating season is over, you could take all your TRVs offline if you wanted. You might need to re-insert the batteries temporarily to make sure the pin retracts fully and you can re-mount them. That's probably my plan anyway, as I don't really plan on using or observing the air / temp measurement data during the warmer months.
