I have a Smart Thermostat and an Extension Kit and/or Smart Radiator Thermostats installed and the app shows that there is no remote access. What does it mean and how can it be resolved?

The Internet connection at your Home is temporarily interrupted

The most common cause for “no remote access” is a temporary issue with the Internet connection in your Home which usually resolves itself. You can learn more about this in our article: What happens when the Internet connection is temporarily lost?

If the Internet disconnection persists, please check that your router is powered and if so then reset the router.

The Bridge cannot establish a connection to the tado° server

Please check the LEDs on your Bridge for troubleshooting.

The radio link between the Smart Thermostat, the Extension Kit or the Smart Radiator Thermostats to the Bridge is interrupted

In rare cases, the radio link between the Smart Thermostat, the Extension Kit or the Smart Radiator Thermostats to the Bridge can be interrupted. This also means that the devices cannot exchange information any longer. If you change a setting on the Smart Thermostat or Smart Radiator Thermostat, they will display that there are changes that have not been synchronized with other devices yet.

The batteries of the Smart Thermostat or Smart Radiator Thermostat are empty

If the batteries of the Smart Thermostat or Smart Radiator Thermostat are completely empty, the display will not light up anymore when you push the button on the bottom right or turn the knob. Please replace the batteries.
