What they did
u/youplaymenot saw another Redditor's Android TV home screen built on Home Assistant and wanted the same. Their Home Assistant was already connected to ChatGPT, and they gave it adb access to the TV through their Mac mini. They described the look they wanted and let it work. It navigated the TV over adb, pushed the launcher APK to it and configured it, with home screen tiles drawn from their Home Assistant cameras and sensors.
How it went
It took about an hour and the poster was very happy with the result. The home tab shows the front door camera, weather and house temperature, a second tab shows all cameras with one enlargeable, and an Assist tab holds entities they can control. They found watching it drive the computer and TV both impressive and a bit unnerving.
Worth knowing
The post does not say which ChatGPT harness had the adb access. Commenters pointed to Hearth, a ready-made launcher with the same features, which may be quicker than having an agent build one.
