Boiler came on in middle of night

Rustywheelnut

My boiler came on full blast in the middle of the night last night! All radiators and hot water were set to off on the app. The wireless receiver had the radiator light on. I pressed the manual button to turn off the heating but it came back on, even though the app still showed all the radiators were set to off. I ended up switching off the power to the heating so that I could go back to bed!
I restored the power this morning and it all seems to be working as expected.
Any ideas what may have happened?

Do you have any zones with Early Start enabled? If so, tado can decide to turn the heating on well before set points for higher temperatures if it thinks it needs time to get there. This is the case in my poorly insulated home especially on cold nights.
