App functions, however: I encountered a bug and could not connect my thermostat. Had to contact support which took 3 weeks . Also there is no option to temporarily boost heating, i have to change my entire weekly schedule! Insane. Sometimes i work from home as a one off and want to have heating for one day. If I forget to change it back then it would heat the house continuously... Forever. My previous 10 year old boiler had this option!

Update: The problem has not been fixed yet. Then, all of a sudden came "maintenance notification with no reason and I had to go through registration again and with the correct data (qr code) it was not working at all. I had to delete all the data until it worked. The emails won't be answered,although they say,"we get back to you as soon as possible. Recently, I'm obliged to register with email, and to my wondering comes the "something went wrong, please try again." Really disappointing

The app has great functionality and is everything I expected. One important prerequisite is not mentioned thoug - to se up the app, the boiler pretty much has to be fully set up and running. It would be nice if the gas consumption would show consumption per time unit as graph/list and not total of last 7 days, month, year. That would enable to analyze consumption over time.
