I have recently purchased the IQAir HealthPro XE, I have the older model that uses IR and it made a huge difference in my basement office so I added a new one.
This one appears to have an API via the cloud and shows up as a device in my iqair dashboard. Although I am not seeing any of the settings exposed in the current api docs.
It also has Bluetooth, so potentially two paths we could explore
Anyone else working on this? So we could put heads together on it.
