I stopped using the Combee stick as I wasn’t keen on the software integration within HA so I use a CC2531 USB dongle with Zigbee2mqtt.
The CC2531 sees and connects fine with the SP222 but I’m pretty sure the Combee did too
I now only really use the SP222 plugs as repeaters on my system as I have lots of WiFi Smart Plugs with energy monitoring that I prefer
It’s a real shame the INNR plugs don’t have energy monitoring as I actually prefer using Zigbee devices over WiFi devices.
I did see these on Amazon recently which look interesting
