Controlling Sonoff 4Ch Pro in Homey

I got Homey to switch off from Home Assistant but it’s so frustrating so far I’m contemplating returning it. I have a setup with multiple Sonoff minis which are ok, but also Sonoff 4Ch Pro R2 and I just can’t manage to set them up with Tasmota/Mqtt to use the 4Ch. It always adds as just one single device. Could anyone please help?
Many thanks in advance
