I have had these notifications, checked on the app which shows batteries are ok and then tested and getting 1.5volts, complete mystery. Can Tado explain?
@Merleychris I have had similar with two trvs within their first month. Mine were low in the app and got the email and the valve stopped working but after changing to new batteries and then back to the original "dead at 1.5V" batteries everything is ok.
I'm beginning to think that this is a tado° issue with regards to how the battery level is being "interogated" by the tado° systems.
It seems to me that tado° need to devote a little time and effort to determine what they (tado°) need to do to produce a "Low Battery Notification" feature that is "fit for purpose"..........probably not very high in tado°s list of priorities though.
Not sure if sending an email is the most efficient way of communication.
Personally I'm not too bothered which delivery method tado° uses for the "Low Battery" notification........however I would prefer tado° to sort out their calculations for interrogating the data.
