Feedback: Battery Sense and Orion Smart DCDC is working

[HBK1]

Victron Battery Sense reports as Battery Monitor and presents BATTERY_VOLTAGE and TEMPERATURE. Orion Smart DCDC needs a filter on OUTPUT_VOLTAGE since it reports 0x7FFF=32767 when engine is off=Unavalible. Both are working ok together with a Smartshunt and MPPT on the same ESP32.

See below config for DCDC and Battery Sense:

Similar results here with an OrionSmart DC-DC charger. If the charger is off, the output voltage is shown as 327.67 V. This should be filtered.

Everything else, including data from my SmartSolar 75-15, is displayed as expected. Great Work!

Should the component submit no value (like your filter), 0.0 or NAN in this scenario? I am unsure what would work best.

[HBK1]

My filter is causing HA to keep the last value which may not be so good. I would rather prefer 0.0 as this is the real value and what keshavdv does. NAN will present Unavalible in HA and may disturb further calculations of energy.

Hi @HBK1, can you please test the changes? You might need to add refresh: 0s to the external_components to ensure you use the latest version for testing.

It is working ok with 0.0V , Thanks!

There is a warning in the log, is this anything to be worried about?

The warning is because EspHome changed the log level of this message from verbose to warn. Tracking this warning in a seperate issue #22.
