I know I should have got the ZigBee version, but couldn't find it at the time. I presumed Hubitat's Add Device feature would have a "generic wifi" version just like the Zigbee & Z-Wave ones.
No... Too many variables with wifi. 1st for hubitat to support it natively it would have to have a local api. Those switches are cloud based so that's an automatic no go. @kkosev has done some work with the tuya hub integration but that's about it.
