As @Arnt_Soloy pointed out; the fan needs the key to create a bonded connection. Hence, it is not possible to integrate the fan directly with Homey. If you use Home Assistant parallell to Homey, it is however possible. I have set up Home Assistant on a Raspberry Pi 4B and managed to control at least the fan speed this way. Then I connected Home Assistant to Homey with the Home Assistant Community app. Pherhaps too large-scale for most users, but possible if you really want the fan to be controlled via Homey.
