I have a very strange problem with my evohome system. The main controller recently reset itself - not sure if this was from a software upgrade or it may have lost power for a while.

When I restarted it, all of the rooms / zones I had set up have been renamed. E.g. the hr92 in the living room is now called 'dining room' (we don't have a dining room), the hr92 in the hall has now been renamed 'living room'. All of the rooms have been given a seemingly random / made up room allocation.

When I go to the HR92s, they initially show their proper zone name but after a couple of seconds they're renaming themselves to the 'new' names from the main controller.

Has anyone seen this happen before? And is there any way of getting my old zones back or do I need to start from scratch?
