I just connect a Sercomm SZ-ESW02 (aka Telstra Smart Plug 2) paired fairly easy. I edited @kkossev tuya mtering plug driver to include the fingerprint for this plug, but I'm guessing the power reporting is off by a factor of 100x, it reported a kilowatt/minute consumption for a Tapo power strip with only a Google mini, zooz Siren and a Tuya USB repeater plugged into the strip, and the TAPO strip itself plugged into the Sercomm outlet. Used Kill A Watt to verify the power reporting is very inaccurate.
Besides the wonky power reporting the zigbee repeater performance is incredible (Centralite made the guts?), and for 15.99 for 5 plugs from ebay, I'm happy.
Krassimir, is there anyway to adjust the power reporting in the driver?
Also tried inbuilt Generic Zigbee Plug driver and got same exaggerated 570 watts

ebay link, if you need a strong repeater(UL Listed)
PS: On Z2M when the identical device is paired the reporting seems very accurate:
