Problem
An example of this is when you change the mode of a zone from Timer to Footprint, or from Off to Timer, or when you switch off the heating from the My House page and the zones turn back on again.
Reason
The Genius Hub possibly did not register you turning the heating off on the My House page or changing the mode. Sometimes (normally when there is a poor internet connection), the message from the app does not get through to the Genius Hub, despite the app looking like the setting change has been made.
This is because the app is designed to be responsive, so it shows the change straight away to make the app easier to use. However, if the message does not get through to the Genius Hub, the app will revert to its previous setting after a few seconds. This is why you sometimes see the app flick from one setting and then back again.
To ensure that a change has taken, wait for the screen to update based on the new action (e.g. the set temperature to change or the heating indicator to change on the tile)
