Hello,
I have just received my N20.
Not very experienced with ESPHome but I did get firmware compiled and the unit is working over Wifi rather than ethernet.
I am in Canada. My electrical service is 120V/240V split phase.
Line 1 to ground is ~120V, line 2 to ground is ~120V, and L1 to L2 is ~240V.
I bought the N20 with its two voltage inputs in the hope that I could measure both 120V circuits and 240V circuits.
Is there a way to change to configuration for individual watt and kWh sensors to use the Line 1 plus Line 2 voltages?
So for example right now I have a 240V 4000W heater running.
There is no 120V load and no neutral so it only needs a single CT, but the voltage is the sum of L1 & L2.
For example my sensors currently read:
bl0910_1_current_1: 16.086A
bl0910_1_power_1: 1874.9W (incorrect)
bl0910_1_voltage: 117.3V
And also:
bl0910_2_voltage: 118.2V
The kWh would also be incorrect.
Can I adjust the yaml so that it calculates bl0910_1_power_1 based on bl0910_1_voltage PLUS bl0910_2_voltage?
But ONLY for that specific CT input?
So that other CTs on 120V circuits still calculate correctly?
It seems like it may be able to calculate this within Home Assistant.
I've already made a helper that adds the two voltage sensors together.
But they don't seem to have implemented the multiplication/product helper.
It would be immensely simpler if it could be implemented in the yaml.
Thank you
