One thing I see wrong is that phase_b needs a "gain_voltage: 7063", like with phase_a. But that shouldn't affect the current reading, only the power calculation.
Can you confirm the same thing happens on other current channels or is it just one? If only one check the solder joints for that connector and surrounding caps/resistors. It's possible there is a cold joint. I usually only see this when the gain is turned up.
Looks like 1 of the power monitoring ICs is working fine. CT1-3 all have this issue while 4-6 do not. Didn't see any cold joints but I ran around both ICs just cleaning things up and putting a little pressure down. Seems to have fixed it for now!
I'm either missing something in the documentation or something is going on with my board. After I get my calibration tuned in on a 60w light bulb, the amperage is wrong when turning the bulb off. With no current flowing, it reads about 0.2 amps. Turning the light on again yields (accurately) 0.44(ish) amps. Completely unplugging the CT clamp from the board yields 0.2 amps as well.
I have v1.3 of the 6 channel hardware and haven't altered it in any way. Looks like JP8-11 are not connected. I'm using esphome like so:
Any idea what I'm doing wrong here?
