Radiator thermostat batteries die without warning?

Hi Folks,

I really hope that tado’s technical support team pick up on this!

I’ve had 3 separate radiators thermostat batteries die without warning. They still show up as fine in the app. The only way I noticed was by touching the radiator and then manually turning the thermostat to be greeted by the “[ ]” image.

Great! So it just doesn’t bother telling me!

This did used to work! Maybe it broke in the latest software update 66.1 which is present on all these radiators btw.


  • Happens all of the time for me for over a year now. Tado claimed they would fix it but never did so. What is bizarre that rads with the same firmware - some report and others do not report low battery.
