Battery_float_voltage writing

[helnora]

Issue related to

Sunsynk / mbusd Home Assistant Add-On

Describe the issue/bug

Battery_float_voltage, battery_absorption_voltage and battery_absorption_voltage are shown in the addon, and values can be changed. When changing the values, values in inverter was set to 0. The log from the addon below(shows nothing wrong I think).
I had to reset the values manually from the inverter screen.
This is not something I would change often, but It would be nice if it worked when it is in the addon.

If the minimum of the battery_absorption_voltage sensor in Home Assistant is 0, then the previous commit should fix it.

Else I would need more info, like config etc

In the latest edge version, you can add a trace to a sensor using overrides

Search for trace in the config https://kellerza.github.io/sunsynk/reference/multi-options#sensors

SENSOR_OVERRIDES:
  - battery_absorption_voltage.trace=1
