I do not like the newest update layout. Yes, you can see all the days better, but you've taken off the colour coding (for hot water heating) so you can't see at a glance any difference between comfort and economy mode. The labels don't show up if the gap is too small - useless when you're looking on a phone! Bring back a colour difference please- now it's all just pink! The app is still very slow to update the actual realtime temperature.

Since the last few updates it takes over 40 seconds displaying the 'Room scene image' before the home page with current system status, very frustrating, quite often I go to the main controller box to avoid the delay. This delay is repeated when changing any settings for these to sync with the main unit and visa versa. The app also reports a weak wi-fi signal when it is very strong, the controller unit sitting 2 m below the router & no errors reported on the main controller, so why on the app?

Moving to a 1 as this version seems to not control the unit. I press off and it stays on. I press on and it turns on and then goes to off. Unreliable. Does not work with Ifttt also no simple timer (IE turn the unit on for 60 minutes)... Also everything always goes back to heating as default, rather than the last setting.
