Tado Loss of Time Synchronization After Power Interruption

Tado Smart Thermostat shows time or schedule shifts after power cuts.

Possible Causes

Thermostat relying on cloud for time sync, Internet Bridge offline after power cut, Router slow to reconnect, No internal backup clock

Safety first: No electrical work required.

Ensure bridge online: After a power cut, verify that the Internet Bridge has reconnected to the router and Internet (LEDs on and app shows online).
Allow resync time: Give the system 10–15 minutes to resynchronize time and schedules from the cloud.
Check router boot order: If the bridge powers up before the router, consider plugging the bridge into the same power strip so they restart together.
