Grid power

[corna]

Hi!

I'm trying to setup the grid meter for my house. I have a ABB Terra AC (OCPP) and a MQTT meter which reports the power consumption of my house, charger excluded (i.e., the charger power is not measured by my meter). So, my grid meter should be

grid_power = my_mqtt_meter_power + abb_terra_ac_power

How do I express this in EVCC?

Thanks.

a custom meter with calc plugin

power:
  source: calc
  add:
  - source: mqtt
    topic: ...
  - source: http
    uri: localhost:7070/api/state
    jq: .loadpoints[0].chargePower

Works, thanks!
Am I forced to pass through the HTTP APIs? Is there an "internal" source?

You can also use the MQTT Api to get the charge power.
I have no idea, how to get it directly from the charger.
