Smartthings Plugs not reporting energy usage

Hello,

Posted this on reddit a few weeks back but didn’t really get anywhere so I thought id try here. I have about 10 ZigBee Samsung smartthings UK plugs that report energy and power usage. They are part of a large ZigBee network using ZigBee2mqtt and a Sonoff 3.0 usb dongle.

After arbitrary amount of time, a few hours to a few days, many of the plugs stop reporting energy usage. There still online, reporting and actioning switch status but no energy usage. I’ve tried rebuilding the ZigBee network with a different bridge (zzh) etc. Still see the same thing.

To get then back writing I need to go into z2m and go to the individual plug reporting menu and refresh the reporting interval for energy and power.

Has any one seen this before? Any suggested fixes?

Thanks
