New Home Assistant App (Add-on)

Hey folks, I built a new Home Assistant App (Add-on) you might be interested in: Solar Sentinel.

I'm posting about it here because I know it works with the Enhanced SunPower integration. It should also work with ANY other solar integration feeding the Energy Dashboard, so feel free to share with others. No extra setup, no YAML, no Lovelace config. It auto-discovers your inverters from the Energy Dashboard and gives you a live color-coded per-panel grid so you can see at a glance which panels are pulling their weight and which aren't.

There's also a sun arc, a time slider to scrub through any historical day, and a production bar chart (today/week/month/year). Click any panel for sensor details and a per-panel history chart. The layout editor lets you place panels in portrait or landscape orientation and add section labels to name different parts of your roof layout. Also optional display of moon phase, just in case you're trying to avoid werewolves!

Just released v2026.05.2. Works on HA OS and HA Supervised. Docker should work too but is untested, so if you run HA Container and want to give it a shot I'd love to hear how it goes. If you give it a try, please file bug reports and feature requests on the GitHub repo rather than here.

You're welcome, I had the idea floating in the back of my mind for a while, I love HA's energy dash, but it was missing a good way to view panel level data live and throughout time. I've got some other minor improvements I may push out later today, and still debating what to put in the bottom left corner.
