Very good but!
Although the app performs well most of the time one aspect of the app does not. The hot water block feature does work well if no other features are required at the same time. For example The EVU feature used for controlling heating timings does not work if the hot water block is also initiated. This is very confusing because these two features are included within the Thermia app why? However you can have these two features running together if you input your timing features via your ashp midi unit and not your Thermia online app. Come on Thermia let’s get these important issues put right and included for its end users.
