Hi all! I just released a small macOS menu bar app called Peek to monitor Home Assistant sensors. I originally built it so I could keep an eye on my solar setup at a glance throughout the day, and I ended up finding it so useful that I decided to polish it up and share it.
Peek has two areas for sensors. The first is directly in the menu bar, for information you want visible at all times. The second is in the menu bar dropdown, which works well for less critical sensors that are still nice to check occasionally.
It connects to Home Assistant using a WebSocket, so everything updates in real time, similar to the HA dashboard.
Right now the app is focused only on monitoring sensors, so it can’t trigger actions yet, but that’s something I may add in the future.
The app is completely free, open source, and notarized, so there are no weird Gatekeeper warnings when opening it. There’s also no tracking and no data sent anywhere, aside from occasionally checking GitHub for new versions.
A large part of the app was built with the help of AI (see the AI disclaimer in the README). If that’s not your thing, that’s totally fine and we can still be friends. 
Feel free to give it a try, and I’d love to hear any feedback!
