What happens when the batteries of my tado° devices run out?

If the batteries of your tado° devices are low or depleted, tado° will not be able to control your heating as intended. 

For example, the display of your Smart Thermostat may flicker and the touch arrows may stop responding. It is also possible that your Smart Radiator Thermostat won’t close fully, which may cause your radiators to heat even when not needed. 

Your tado° devices will notify you when it’s time to replace their batteries. Look out for these low battery indicators:


If any of your devices are running low on battery, this will be shown in the device list in the tado° app. 

You will also receive an email when the batteries in your devices start to run low. Please make sure that you replace your batteries within one or two weeks from receiving this email so that your devices stay connected and work well.

You will not lose your data or Smart Schedule settings on tado° if your batteries run out. However, you’ll not be able to control your heating via your tado° devices until you replace the batteries.
