Victron integration with ESP32 - Solar works but not the BMV

ESPHome
1

Hello,

New to the forums as well as home assistant. It’s absolutely fantastic and i’m loving it! So thanks everyone in the community.

I found this GitHub - Fabian-Schmidt/esphome-victron_ble: Use official Victron BLE endpoint for fetching data from Victron devices via Bluetooth LE via ESPHome.
and had pretty good success. Except for my Victron BMV-712 Smart

I’m trying to get my “batteries” into Home assistant with no luck.

The Setup:
3 Victron MPPT solar charge controllers. (StBd Solar, Port Solar, Arch Solar)
1 BMV-712 Smart (essentially the “Victron Smart Shunt”)
Using EPSHome/ESP32.

Under the Energy tap i’m able to add the charge controllers under the “solar” section. However I can’t seem to add the battery, it’s not really showing what i need? I think? Like what entities should i be using or am i wrong in thinking I can integrate the BMV as the battery?

Here is the code i’m using:

I dont use this integration, but I will try to help you anyway as noone else replied.
From my understanding you need BATTERY_POWER (Watt) and use a riemann sum/intergration of that sensor for the kWh.
As the battery power may be negative you also need to differentiate between import and export with a template sensor like this:

{% if is_number(states('sensor.BATTERY_POWER')) and states('sensor.BATTERY_POWER') | float(0) > 0 %}
    {{(states('sensor.BATTERY_POWER') | float(0)) | round (3) }}
{% else %}
    {{(states ('0.0') | float(0)) |round(3) }}
{% endif %}

and < 0 for whatever minus power is defined. Then you have two Watt sensors (state class: measurement, device class: power) of which you need to create the riemann sum. The riemanns are the sensors you need to select for your energy dashboard.

The Smart Shunt doesn’t output a Watt figure, but rather a Current in Amps. You would have to convert that to Watts.
