Owon PC321 Zigbee Power Monitor on Split Phase?

Has anyone connected the 1-phase/3-phase Tuya Zigbee power monitor Owon PC321 to US split phase?


I think it can work since it has 3 clamps and 3 voltage sensors. I’d use two clamps only, one for each 120V line. And the corresponding voltage sensor for each. Based on instructions for a somewhat similar model but based on WiFi and specifically designed for US split phase, the third voltage sensor would be connected to the neutral.


I want to get the Zigbee model working because it’s supported by Z2M.

Got word from Owon support. Yes, it can be used for US split phase and the connection described above is correct.
