Tibber - Sensor for power consumption for electric car charging

Feature Requests

I implemented a simple SoC sensor for HA now (that’s all I need – probably can be easily extended for other data Tibber delivers). No Node Red required.
You just need a free Tibber account and configure your Polestar there. No contract required. Sensor refreshes every 5 mins, but you can choose any other scan_interval.

First, create a shell script getSoC.sh in HA config folder with this content and replace your Tibber credentials (email and password):

#! /bin/bash

AUTH=`(curl https://app.tibber.com/login.credentials -H "Content-Type: application/json" -d '{"email":"[email protected]","password":"secret_pw"}')`   

TOKEN=`(echo $AUTH | grep -o '"token":"[^"]*' | grep -o '[^"]*$')`

SOCJSON=`curl https://app.tibber.com/v4/gql -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" -d '{ "query": "{ me { homes { electricVehicles { lastSeen battery { percent } } } }}"}'` 

SOC=`(echo $SOCJSON | grep -o '"percent":[[:digit:]]*' | grep -o '[[:digit:]]*')`

echo $SOC

Then add the following sensor to the configuration.yaml:

command_line:
  - sensor:
      name: BEV SoC
      command: "sh /config/getSoC.sh"
      unit_of_measurement: "%"
      scan_interval: 300
      device_class: battery
      value_template: "{{ value | int }}"

That’s all it takes…
