Power does not show negative values. about ina HOT 4 OPEN

How are you calculating "Power"? Are you using "getBusMicroWatts()"?

from ina.

I output to Home Assistant with a script via EspHome.

i2c:
sda: D2
scl: D1

sensor:

• platform: ina226
  address: 0x40
  shunt_resistance: 0.0005 ohm
  current:
  name: "INA226_1 Current"
  accuracy_decimals: 1
  power:
  name: "INA226_1 Power"
  accuracy_decimals: 0
  filters:
  • lambda: return x*2.047;
    bus_voltage:
    name: "INA226_1 Bus Voltage"
    filters:
  • lambda: return x*2.047;
    shunt_voltage:
    name: "INA226_1 Shunt Voltage"
    accuracy_decimals: 0
    filters:
  • lambda: return x*107800;
    max_current: 100A
    update_interval: 10s

It may be possible to correct the formula so that Power has a negative value.
I use with shunt 100A 75mV.

I have never used Home Assist or EspHome so I'm not sure what that script does. How does it calculate power?

I've updated the "getBusMicroWatts()" function to return negative Watts, but I don't know if that is the function you are using.
