Monitor Switch
Monitor Switch is an MIT-licensed service for switching a monitor’s input and controlling its DDC/CI features through a browser interface, HTTP API, scripts, or Home Assistant. It is designed for people who use one monitor with multiple computers, including when the computer currently displayed is asleep or off. Where a monitor exposes the controls, the service can adjust brightness, contrast, volume, mute, picture mode, colour temperature, RGB gain, and black level. It can also read usage hours, firmware level, refresh rates, and power state. Editable profiles set monitor values and can replace incorrect capability detection. For Home Assistant, MQTT discovery presents profile features as entities such as selectors, sliders, and sensors. The service runs on a Raspberry Pi connected to the monitor by HDMI; setup requires Raspberry Pi OS and SSH, and installation uses an Ansible playbook. The project is described as usable but not yet released. Hardware verification is reported only for a Samsung Odyssey G9 with a Raspberry Pi Zero 2 W; other monitors have not been verified.
