Simple docker image to use powerwalker winpower agent with UPS that support it.
Sample docker command:
docker run --name winpower -d --privileged -p 8888:8888 -v "/dev/bus/usb:/dev/bus/usb" enolgor/winpower:latest
Sample docker-compose:
version: "3.7"
services:
winpower:
image: enolgor/winpower:latest
privileged: true
ports:
- 8888:8888
volumes:
- /dev/bus/usb:/dev/bus/usb
restart: unless-stopped
You can then access the web interface at https://localhost:8888 or poll the state of the UPS at https://localhost:8888/0/json in order to run further automations.
For example, upsmon is a service that fetches the status from winpower, can post status changes to a web service and run a script after a timeout on "AC Fail" status.
