tado° smart thermostat — wi-fi keeps dropping
Why does my tado° smart thermostat keeps dropping?
The short answer
App says the heating is offline, usually right after a new router arrives. On the WiFiXpert Compatibility Index the tado° smart thermostat scores 82/100, and its weakest check is "Easy to fix when it goes wrong" — which is exactly where this problem comes from. The bridge light tells you plainly whether it's the internet or the heating.
We publish what breaks with each router and mesh system, and the setting that fixes it.

- Check the bridge is still plugged into the new router.
- Restart the bridge by unplugging it for 30 seconds.
- The heating keeps to its schedule offline — you're not left cold while you sort it.
Before you spend anything
- Not a Wi-Fi spend. If the valves lose the bridge, move the bridge nearer the middle of the house.
