Hihome fully suported?

I am using Homey since yesterday cause I hop this will connect all my devices in house. I got a few HiHome products. I use this one (Hihome Zigbee wireless switch - 4 zones - 12 functions assignable) and I can ee it in the Tiya app but not at Homey. Same for Hihome Zigbee Temperature & Humidity sensor. I can see the 3-pack-hihome-smart-wifi-plug, so it looks like not every device og Homey is supported.

Do you know how to add the rest of my HiHome devices?

Does someone answer this question please ?
