Tuya Single Phase Energy Meter - incorrect readings

Not strictly HA related but I was wondering if anyone else has seen similar.

I’ve got a Single DIN type single phase energy meter. Measures using a clamp.

Readings are working, in so much as the figures in the Tuya/Smart Life app match what is in the Tuya and LocalTuya integrations. Problem is that the numbers don’t make sense.

I’d assume it reads voltage and current then calculates power from those.

Example of readings
Voltage - 234.5 V
Current - 2552 mA
Power - 337.5 W

Power is wrong based on the other two.
I’d expect power to be 598.44 W

Compared to another energy meter I have, I’d say Power is actually closer to being correct than Current.

Has anyone seen similar?

514AAn+UV-L.AC_SX425

I wonder if it’s providing power factor?
Perhaps the “Power” is the “real power” of the circuit and the Voltage * Current (VA) is the “apparent power”…
Then the power factor (pF) would be the “Power” as a percentage of the VA.
