# eg4-battery — local Docker deployment.
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# docker compose build # one-time, after changes to Dockerfile / requirements / source
|
||
|
|
# docker compose up -d # start daemon in background
|
||
|
|
# docker compose logs -f # tail the daemon log
|
||
|
|
# docker compose down # stop + remove
|
||
|
|
#
|
||
|
|
# This deployment runs side-by-side with the systemd `eg4-battery.service`.
|
||
|
|
# Stop systemd before bringing this up, or each pack will be polled twice
|
||
|
|
# per cycle (and HA will see duplicate publishes from two MQTT clients):
|
||
|
|
# sudo systemctl stop eg4-battery.service
|
||
|
|
#
|
||
|
|
# Side-by-side cutover, once verified:
|
||
|
|
# sudo systemctl disable --now eg4-battery.service
