Issue related to

Sunsynk / mbusd Home Assistant Add-On

Describe the issue/bug

After the firmware upgrade from version: 9.0.2.2 to 9.0.2.6 grid power is showing incorrectly. I believe it is expecting WATTS and getting KW. But i could be wrong when connecting to mbusd and checking the inverter values for 169, 168 and 168 i get the following

Register 167 = 94
Register 168 = 0
Register 169 = 94

When checking on the inverter is was 940W Apologies in advance if i missed something obvious.

Expected behaviour

Not 100% sure but i think it needs to be multiplied by 10?

when i use the below it shows correctly


  - platform: template
    sensors:
      sunsynk_grid_power_scaled:
        friendly_name: "Grid Power (Scaled)"
        unit_of_measurement: 'W'
        value_template: "{{ states('sensor.sunsynk_grid_power') | float * 10 }}"

If the definition of the sensor was changed by the firmware upgrade you can redefine the sensor (as a custom sensor)

Currently 169 is defined as:

Sensor(169, "Grid power", WATT, -1)

Adding the following custom sensor should override the standard single phase sensor

Sensor(169, "Grid power", WATT, -10)

If there are other sensors that also changed, we might need a new definition. Existing ones are defined here: https://github.com/kellerza/sunsynk/blob/main/src/sunsynk/definitions/

This changed worked, thanks! I will work through the definitions to check what else they changed.

Everything else looks to be working. Thank you!

Happy if we close this one.
