Develop a "basic backup schedule" mode for when Tado outage or loss of internet
tado EDIT 10.02.2021: Please read my statement on this topic here: https://community.tado.com/en-gb/discussion/comment/22789/#Comment_22789
When Tado devices lose access to the Tado servers, either due to a Tado server outage (as has occured a few times), or due to temporary internet issues at the property, the Smart Radiator Valves effectively stick in their current schedule temperature state. This means the heating can fail to turn off overnight, fail to turn on in the morning, fail to turn on when returing home etc, and require the user to manually activate/deactivate each zone on a zone's device.
I understand that the "Smart Schedule" can't be used without an internet connection as Tado uses data such as the weather outside and the user's location to decide how the schedule should operate, but during an outage the Tado system should at least fall back to a basic schedule state, where it just follows the timing schedule like a normal, non-smart progammer does. Currently, without an internet connection Tado is significantly worse than a standard "dumb" programmer, it should be at least the same.
