This should work with SmartThings just as a zigbee on/off switch. Has anyone tried it yet? This would be a good UK substitute for the similar GE switch used in the US.
Hmmm. That’s interesting. I have a standard 240v outlet outside that I could probably replace with this.
For what it’s worth…
I tried the Osram Smart+ plug indoor version half a year ago… Don’t know if it the same tech inside… 
It connected fine and worked with the built in DH…
But as a Zigbee repeater i wasn’t impressed - experienced a few drop off’s…
