This is very interesting, I've been increasingly frustrated with Daikin's approach to mobile control and the incredibly poor execution of the original wifi module/automation:
- the wifi module and temperature sensor are right next to each other, which was causing the unit to read temperature 2-3 celcius higher than actual due to wifi sensor heat (measured by another temperature sensor on the other side of the unit). This was fixed in a software update, but seems like poor design
- it looks like the original wifi module uses a lot of power, at least according to the app readings. Didn't verify this one, but it tracks with how much it heats up even if the unit is completely off
- no way to connect an external temperature sensor, so even with a software fix to the temperature sensor reading, my room is consistently 2-3 degree celcius colder than the set temperature
- there are no release notes for the official firmware updates so you never know what can break if you update (but an update did fix the wifi module heating issue)
- the (new) app had power usage data for the past couple of years. Now they decided to only store a year? Or maybe just deleted the old data. Either way, now it's lost without any notice or way to archive it

That said, how likely is it that Faikin causes a hardware failure in an indoor or outdoor unit in case of a software bug? I'll definitely try it but I'm a bit uneasy with an open source software designed for what seems like a massive range of devices, and no way for the maintainers to accurately test against each one
