Hi HN, I wanted to share a CLI tool I've created since it might be useful for you:
activitywatch-exporter is a CLI tool that uploads the ActivityWatch data from the aw-server API to influxdb on a daily basis. This can be used to store the statistics and analyze the long term trends with grafana for example (I've included an example dashboard in the repo). I have it set up with podman quadlets in my home server and run it every night.
Sharing it here since it might be useful for more people.
