Doesn't have backward update from the AC when settings are changed from the remote. Also NEEDS quick settings - save some settings into a single quick settings, that can be activated with a single click. For example, during the night I set lower temperature, Indoor silent, floor heating. I want to be able to do that with a single tap. It's annoying to have to do it every evening.

Adding airco and heat pump can be a bit tricky but with some time I managed to do it. But what is incredibly strange is that I can't set the temperature to 0.5 degrees on a schedule while manually it is possible. The device also shows temperature in 0.1 degrees. For my living room I need my temperature to be 20.5 degrees to be comfortable. It should be a simple solution and will help a lot of people.

Slow, disconnects regularly from very good WiFi, setpoints in schedule only per whole degree while in the app per 0, 5 degree, energy consumption reports are regularly inaccurate and changes regularly during the same day. I'm very disappointed in Daikin, I thought is was a top brand but it turns out I could have better chosen a different and much cheaper brand.
