IMPROVEMENTS

Radiator Thermostat II [+M]

Optimized battery consumption during updates

For the Radiator Thermostat II [+M], increased battery consumption could occur during the phase between downloading and activating a firmware update. To prevent unnecessary battery consumption, firmware updates for this model will now be installed automatically after they are downloaded. We are already working on a solution that will allow you to use the familiar manual control for update activation again in the future.

Note: Other models, such as the Radiator Thermostat and Radiator Thermostat II, are not affected by this change.

Smart Home Controller II

Improved network connection stability

In rare cases, the Smart Home Controller could lose its network connection and fail to restore it automatically. This issue has been resolved. A manual restart of the device is not required.
