Script description

Displays the current EVCC home-battery state of charge and live charge/discharge power as a permanently rotating AWTRIX NG script app.

Requirements

  • AWTRIX NG connected to the same MQTT broker as EVCC
  • EVCC battery topics enabled

MQTT topics

  • evcc/site/battery/soc — state of charge in percent
  • evcc/site/battery/power — battery power in watts (positive = discharging, negative = charging)

Setup

  1. Open the AWTRIX NG web interface.
  2. Go to Scripts and create a new script.
  3. Paste the code and save it.
  4. Add the script to the app rotation if it is not enabled automatically.

The text is green while charging, orange while discharging, and gray while idle. Values update immediately when EVCC publishes new MQTT messages. The ±50 W threshold prevents small standby fluctuations from changing the status.
