I want to repurpose an old Dell Laptop that has Windows 10. The CPU is an Intel I3 and the power consumption is between 9 and 11 watts with Windows. This would make an excellent Linux machine with Home Assistant installed. I want to leave it on the shelf running HA 24/7 but with the lid closed.

OpenGarage can check garage door status from anywhere, open or close the door remotely, and check the record of recent events through the log and history graph. The controller supports a built-in web interface with embedded HTMLs, and remote access through NodeRed via MQTT. The built-in interface is used for local access and changing configuration/settings, while NodeRed is used for remote monitoring and control.
