Heating stuck off then stuck on!


Anyone else had issues this morning with the heating being particularly weird?

Didn't come on this morning. Tado thought it had come on. As usual care and protect therefore useless.

Reset the main thermostat and the heating came on when I forced it on with the boost rooms option. It wasn't coming on with just the schedule. It's on basic schedule as early start is terrible at this time of year.

Then it wouldn't turn off! Set it off via turn off all rooms. Nothing. No click on the relay at all.

Had to turn the heating off manually at the boiler.

Changed the batteries in the Tado on the assumption it's getting the signal to turn off but just isn't doing it due to dodgy batteries. But if it's actually Tado servers that are the issue how could I check this?
