Export network output sensor

[admiralroflknife]

I have 3 Victron Mptt controllers networked together and the app provides a network output value. Is there a way to parse this to help reduce the message overhead and let Victron do the calculation instead of home assistant?

I cannot access the Victron Network data. Instead you can create a esphome template sensor and aggregate the data on the device so you only submit a summary.

Here is an untested example how such template sensor could look like.

sensor:
  - platform: template
    update_interval: 30s
    lambda: |-
      float solar_CURRENT = 0.0f;
      if(!std::isnan(id(solar15_BATTERY_CURRENT).state)) {
        solar_CURRENT += id(solar15_BATTERY_CURRENT).state;
      }
      if(!std::isnan(id(solar20_BATTERY_CURRENT).state)) {
        solar_CURRENT += id(solar20_BATTERY_CURRENT).state;
      }
      if(!std::isnan(id(solar50_BATTERY_CURRENT).state)) {
        solar_CURRENT += id(solar50_BATTERY_CURRENT).state;
      }
      return solar_CURRENT;

Afterwards you can set the original sensor to internal: true. Internal components will not be exposed to the frontend (like Home Assistant).
