# Full EVCC config — Schön Consulting homelab
#
# Includes: grid meter, 3 PV inverters, 2 batteries, custom charger via HA,
# site config, Tibber tariff.
#
# Use this as a reference when modifying the EVCC config. Replace __HA_TOKEN__
# with a long-lived HA access token.
#
# Installation: Stop HA VM (qm stop 106), mount RBD disk, write to
# /mnt/haos/supervisor/homeassistant/evcc.yaml, unmount, start VM.
# Then restart EVCC add-on via Supervisor API.
#
# WARNING: EVCC add-on overwrites this file on restart. Stop VM, edit, start VM.
