The app is OK, it shows most of the important information. However, the heating schedule is really not handy. Firstly the interface is horrible, it should only show the heating times as blocks. Secondly, the fact that we can only set the temperature by 1 degC is too coarse. A 0.5 degC would be a minimum. The energy part is also not great as it misses the output energy and/or the COP.

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?

Application is very unstable and crashes all the time when changing the modes of different units. It is the same crashes on my wife's phone too. Update: It became e en worse with the new firmware update. All the units are offline and app started crashing every single time I open it. Director(s)/Managers of the IT/Application departments should be fired!
