Another of my cleaned up self-hosted components. This one doesn’t run on Home Assistant, however since it publishes MQTT messages compatible with Home Assistant’s Update integration, it all works automatically without configuring Home Assistant.
updates2mqtt runs as a container, or systems service if you prefer, and checks for new images available for containers, or remote git updates if you’re locally building containers. Update gets published to an MQTT Topic. If you hit the Update button in Home Assistant, it will do a pull and restart to update to the new version. And lots of common things, like Frigate, Immich, Unifi etc show up with icons and release note links automatically.
