Ajax Online Zignito Zigbee Plug Support?

Hi all,

Does anyone know if these will pair as generic zigbee switches, with or without energy monitoring, with Smartthings WITHOUT the Zignito hub?

I’ve bought a few and they do appear after an Add Device scan but get the message “couldn’t get the device’s status” in the app and no functionality works. I’ve tried with and without Edge drivers, same result.

Many thanks in advance!
