Is there anyway to connect a WiFi connected Honeywell Mobile Conditioner to Homey Pro?

Hi,

The smartphone app looks like Tuya (many brands and devices use Tuya stuff “under the hood”).

You can try this:
Install smartphone Tuya Smart app.
Add the airco to this app.

→ when that succeeds, you can control the airco with the Homey Tuya Cloud app.
