If you have two or more tado° devices of the same type (e.g., two Smart Radiator Thermostats) and you’re experiencing issues with one of them, such as connectivity problems, it could be a device issue or something external, (e.g., the radiator/metal valve your Smart Radiator Thermostat is connected to). To help isolate the cause, we recommend performing a swap test.
The swap test will determine whether the problem is with the tado° hardware or if it’s caused by another external factor.
How to perform the swap test for Smart Radiator Thermostats
Remove the Smart Radiator Thermostats
Take both the tado° Smart Radiator Thermostat that is not working correctly (Device A) and a working tado° Smart Radiator Thermostat (Device B) off their radiators.
Make sure to remove the mounting brackets and keep them with their original devices to avoid confusion.
2. Loosen the radiator valve pins
Before remounting the Smart Radiator Thermostats onto the radiators, manually push the metal pin of each radiator valve inwards a few times firmly.
You can use a small coin to help push the pin without hurting your fingers.
3. Reset the Smart Radiator Thermostats
Remove the batteries from both devices (Device A and Device B).
Wait for 10 seconds before putting the batteries back.
Close the battery compartments and wait for 1 minute before remounting the devices. This ensures the devices will calibrate successfully.
4. Swap the Smart Radiator Thermostats
Mount Device A onto the radiator where Device B was originally installed.
Mount Device B onto the radiator where Device A was originally installed.
5. Observe the devices
Over the next 24 hours, observe whether the problem persists.
Check if the issue with Device A is now happening on the radiator where Device B was installed.
Alternatively, check if the issue has moved to Device B when mounted on Device A’s original radiator.
If the problem persists after performing the swap test, please use the tado° chatbot for help. Select the round orange icon in the bottom right-hand corner to open a chat.
To help us assist you, we’ll ask you to send us the following details:
The serial numbers of both devices (A and B).
The specific time and date when you swapped the devices.
The result of the test: Did the issue follow the device or stay with the radiator?
This information will help us determine whether the issue is with the tado° hardware or the radiator/valve.
You can perform the swap test with any of your tado° devices, if you have at least two of the same type in your tado° account. Simply adjust the steps to suit your specific devices.
