The power was off in my house for a bit and when it came back on, I couldn't connect the heat link. That's OK now after a factory reset plus deleting it from the app and adding it again. I also discovered that the wires going into the heat link had come loose so popped them out and back in again securely. Now though, the downstairs thermostat is displaying a temperature perhaps 7 or 8 degrees higher than the actual temperature, and 3C higher than the heat link upstairs. We have a hot water tank upstairs, so it's always warmer up there as you'd expect, even when the heating is off. I've tried holding down the front of the thermostat to force a reset twice, but it hasn't helped. What is going on? I tried taking the thermostat outside where it's currently 11C, the thermostat said it's 25C.
