Ifan03 support

[fireport]

Good morning,
I bought some Ifan03 to pilot my ceiling fans that i will flash with tasmota
In the meanwhile, i'm trying to configure domoticz emulating Ifan03 with a spare wemos d1 flashed with tasmota
I Created a selector virtual sensor but I have no idea how this selector works with tasmota.
When I press the button level {1-3} on the domoticz dashboard, on the console i have this error:

stat/hue/RESULT = {"Command":"Unknown"}
I searched the forum but I didn't find any hint.

May someone help me ?

Thanks !

I think that the problem is related to the fact that Ifan03 expects command Fanspeed:{1-3} but Domoticz sends another command.
