When the internet connection is lost, you can control your heating or air conditioning system via the user interface on the device. However, you won’t be able to control your heating or air conditioning remotely via the mobile or web app.
Depending on your region and specific hardware revision, your tado° V3+ Smart Thermostats store heating schedules locally, meaning they will continue to follow your Smart Schedule, even if the network connection is lost. The rollout of this feature is ongoing.
Changes made on the device interface during this time will only be applied in the app when the internet connection is restored.
All rooms that can’t access the internet will be shown as having no remote access/offline in the app.
Similarly, any changes made to the app settings will only take effect when the internet connection is restored.
