Heating not coming on

For the last couple of days the heating hasn't come on, either with a schedule or if I boost it in the app.
The app shows the rooms as heating but the boiler is not kicking in
Any ideas?

    Can you give us some more information on your set up?

    Do you have an extension kit controlled hot water too? If so, does that work? and do you hear the relays click when you turn on/off the heating or hot water?

    If you don't have an extension kit, does your smart thermostat relay click when the heating is turned on/off?

    I have previously had the issue where my extension kit seemed to lock up. Powering it off for 10 seconds and back on resolved it
