Deskmate

A modern, open-source Windows companion for Home Assistant, in the spirit of HASS.Agent. Your PC shows up in Home Assistant as a device with sensors, buttons, switches and notifications, your keyboard becomes a remote for your home, your phone can drop files straight onto the PC, and the kids' screen time rules run on the PC itself, without a Microsoft account.

It talks to its own Home Assistant integration over one encrypted connection, so there is no MQTT broker to set up (MQTT still works if you already run one). Native on Windows 10 and 11, x64 and ARM64 (Snapdragon laptops included), with a ~3 MB installer.

• CPU, memory, disks, network, battery, uptime, and GPU and temperatures where the hardware allows (CPU temperature too, with a small optional helper).
• Whether someone is at the PC: idle time, last activity, locked or not, who is signed in, a presentation or full-screen video running.
• If you want them: the window you are in, the Wi-Fi name, what is playing, whether the camera or the microphone is in use. Off until you turn them on.
• Your own sensors: is a program running, is a window open, is a Windows service up, or anything a script can tell.
