Energy device (US) 2 phase

Energy

I have an emporia3 modded to work with esphome. Being in the US there are a number of appliances I have that are split phase. One that I am the most interested in is my hot tub. I put 2 clamps on it (1 on each phase) and tracked the usage and it was perfectly matched overlayed. So I took the second clamp off and purposed it elsewhere.

My question is this. What is the “best practices” scenario here? Should I create a template sensor that doubles the value? Or should I modify the esphome code to report 2x before it’s even reported? Wondering what others have done? I have a few devices that will be like this (hotwater heater, stove, dryer, upstairs and downstairs hvac ect)

Yeah, I use a current sensor on one leg and then multiply it in the config. Here is two examples:

      - { phase_id: phase_a, input:  "6", power: { name:  "Dryer Power", id:  cir6, filters: [ *moving_avg, *invert, *pos, multiply: 2  ] } }
      - { phase_id: phase_a, input:  "7", power: { name:  "Range Power", id:  cir7, filters: [ *moving_avg, *pos, multiply: 2  ] } }

Thanks. I didn’t know anyone else had been doing that or not. Seems like the easiest thing to me.
