Now, I've been using this app for 2/3 days. It does its job, but I'll see if it's good enough. For now, the real let-down is all about the missing integration with Google home and SmartThings. I'm not talking about voice assistant. I'm talking about controlling the device from the apps. It's crazy they decided to open up to silly voice commands and decided not to write a Matter Driver that integrates it completely on smart home apps: the result is you miss all smart home automations. Weird.

I second this previous comment: When we use the app to control the unit, setting it to heat it goes way above the temperature it is set. The unit itself records a temperature much higher than its setting but does not switch off the heat. The app doesnt work very well with google home and is missing any integration with homeassistant, custom integrations do not seem to be a possibility.

Having the old Daikin controller app was a bit clunky. This is slicker and better laid out and now I can turn on the units with Google home and use Google assistant. It would be nice to have a button on the main screen to turn all units on without having to go into each unit separately. As a hayfever sufferer I'm loving the pollen forecasts 👍
