Upgrading to V3 from V1
I'm upgrading from V1 to V3 - I've managed to physically install all the new devices OK and get them connected.
My heating is working OK off the new kit, but I am left with all my old devices in the app / web portal. Normally I'd ignore them and just carry on, but my hot water appears to be associated with the old V1 smart thermostat, so isn't working.
I've checked the app, and can't remove the V1 devices (just has 'Help' Centre) as the option on the 3 dots.
Has anyone any idea how I can get rid of the old devices, and associate my new V3 kit with the hot water control?
