It’s been a frustrating experience to get reliable readings from the lite via the Xiaomi integration, but figured out how to integrate it via Homekit into HA and get all the sensors exposed. I
t was a little tricky without an iphone, but I used the qingping app to setup and update the firmware, and then put it back into the initialize mode with a long keypress on top of the device. Then using the qingping app, I told it which wifi network to use, and the password, hit connect, and then put my phone into airplane mode that cut off contact between the App and the air monitor.
Then HA found the device as a homekit device, and I added it using the printed code on the monitor, which for some reason isn’t in the XXX-XX-XXX mode format the integration requires for configuration. Make sure and add the digits this way and it adds just fine. But if you let the qinping app finish initialization, then it won’t add properly as a homekit device. This may work differently on an iphone.
No Xiaomi app, no token nonsense, no yaml edits, etc… It just works.
