If a No data error message appears when you try to access your Energy IQ calculations in the tadoº app, it could be due to the following reasons.
The most common cause of a No data message is a connectivity issue between the tado° devices.
To make sure that your devices are connected, go to your Settings > Room and Devices in the tado° app and check if your Internet Bridge or other tadoº devices are offline.
Consumption data issues
A No data message can also appear if the app is having trouble reading the information provided for calculating your heating costs.
Mixed heating set-ups
When heating set-ups contain both heating circuits and independent heat sources, or use energy for non-heating purposes (like domestic hot water), the tado° app may not be able to estimate the costs and will display a No data message.
