Problem with Xiaomi Zigbee Power Outlet1

Hi guys, I bought a Xiaomi ZigBee outlet, and was able to pair it with Smartthings hub (v2).
However I couldn’t seem to control it, the status in the app would change, but not the actual status of the outlet.
I’ve tried two device handlers found here, and can’t get either to work.
Tried to delete and add into smartthings couple times with no luck.
Anyone got a similar problem?
Wonder if the plug is defective in any way.
Thanks a lot.
