Sure!
I dont have that many units though, but i can confirm that the following units work:
- IKEA Trådfri
- Schneider Micro Module Light Switch (CCT5011-0001)
- GLEDOPTO RGB+CCT LED-list
- Ledvance PAR16 RGBW Value (Not able to change color but otherwise works fine)
The Zigbee network is spanning two storeys and i have not experienced any problems with connectivity
