I'm using the native Owon one and it works like a charm. The one you pointed out which is Tuya OEM has been also integrated on the plugin and works well.

I use something similar. The only issue I have is that the Energy counter is not counting backwards when negative currents (eg solar is producing more the usage). So I use the compute mode of the domoticz device.

I saw that there was a fix in
Dec. 2024 - stable7.1.015 (2024.07) [Issue] - fix bad handling of Owon PC321 negative power
but that did not help for me.

If wired solution are accepted, you can try with DTS238 ZN/S (cheap, Modbus (RS485), works perfectly, with domoticz plugin) or SDM630: they are class-1 meters with 1% accuracy. Check Domoticz wiki -> Plugins
