Hey all, back with another app (addon as they used to be called), this one is for solar panel owners.
I maintain the Enhanced SunPower integration for SunPower PVS systems. When SunPower went bankrupt and the new owners started charging for what was supposed to be a free-for-life app, one thing I really missed was the per-panel view. So I put together Solar Sentinel.
Solar Sentinel is a Home Assistant app that gives you a live, color-coded visual of your entire solar array, panel by panel, right inside HA via ingress. It is designed to work with any solar integration already configured in your HA Energy Dashboard, not just SunPower. If your panels show up in the Energy Dashboard, Solar Sentinel should be able to discover and display them. Testing so far has been done primarily by about a dozen SunPower users, so feedback from other inverter setups is very welcome.
Features:
- Per-panel color-coded grid showing live wattage output; green for strong producers, yellow for underperformers, red for panels that may need attention
- Sun arc showing dawn, solar noon, and dusk with the sun position tracking through the day
- Time slider for scrubbing back through the day to see how your array performed at any point
- Production, Grid, and Battery charts with Today/Week/Month/Year ranges
- Full mobile view that opens automatically on phones and narrow screens with a native phone layout, not a scaled-down desktop
- Layout editor to position panels to match your actual roof layout
- Works with multiple inverters and multiple batteries
- No cloud dependency; reads directly from your HA entities

If you run into issues or your integration is not being discovered correctly, open an issue on GitHub and let me know what solar system and integration you are using. Happy to expand support.
