[Update] Still doesn't work, "could not find device on the network." NO S--T! The app was suppose to connect the device to the network. Idiots. [0-Stars. Doesn't work. Neither the older Haiku app and the "super improved" BAS app works. And apparently they are never going to work. It's just an app, and somehow other people and companies can make working apps without issue. But in this case, super high cost product with total POS accessories and 2 failed phone apps. Pathetic.]

It's okay. Not terrible. Stable but it has a lot of unrealized potential- they have a temperature but the auto fan control only uses motion/occupancy to turn it on. They should have included options to set to run when temp is above a certain temp OR via motion sensor. I have to work around this in home automation software. Also annoyed that I can't control the light from home assistant.

Hi there! We appreciate your feedback and are glad to hear that you find the app stable. We do actually have the ability to set up temperature automation in our app. Select your fan from the home screen, and then select Settings > Fan Auto > Comfort. From there, you can enable "Auto Comfort" and set your preferences.

The app itself seems ok, although it is a bit slow to start. The 3 star rating is for the firmware update feature. Using the app on my Samsung S24+ with Android 15, the fan firmware update process repeatedly failed with a "preparation failed" error on 3 of 4 new Haiku fans. Troubleshooting information was lacking. I decided to try the app on my old Android 9 phone and was able to update the other 3 fans immediately. Please fix the app.
