Store a basic schedule locally in case of crash / lost connection
My Tado system crashed when I went on holiday when the boiler was on. It stayed on max heating until I got home. Quick sums showed it had burned abut £50 in gas (which Tado refunded in the end) but surely it makes sense to store a limited schedule locally, at the boiler controller.
What's potentially worse is if the system crashed in 'off' mode when you're away for a long period in winter. Pipes could freeze etc, it could trash your house.
If the connection is lost, Tado should follow a basic, locally stored schedule, e.g. on 1 hour every 12 hours etc, to prevent freezing but also avoid cooking your house.
