Turn a spare Android device into a smart motion sensor and security camera.
Yakk is a lightweight companion app designed for wall-mounted or stationary devices used in home automation setups.

Perfect for tablets or phones running alongside apps like Home Assistant, Yakk adds motion detection, device wake-up, and MJPEG streaming — all while staying out of the way.

Why Yakk?

♻️ Reuse old Android devices as motion sensors or security cameras
🔋 Low power operation with automatic wake-on-motion
🏠 Built for home automation (works great with Home Assistant)
⚙️ Runs quietly in the background without interfering with your main app

Key Features

📷 Motion Detection & Wake-on-Motion
Let the screen turn off to save power. Yakk monitors motion and wakes the device instantly when activity is detected — ideal for kiosk-style or wall-mounted setups.

🚀 Auto Start on Boot
Automatically launch Yakk (and optionally your companion app) after a device reboot. Perfect for unattended or always-on installations.

🌐 MJPEG Camera Streaming
Turn your device into an MJPEG-compatible security camera.
Access the stream at: http://:2112 and integrate it easily with platforms like Home Assistant.

Designed to Work Alongside Your Existing Setup

Yakk doesn’t replace your dashboard or UI.
It complements your existing apps by handling motion detection, power management, and streaming — leaving visualization to tools that already do it best.

Important Notes

Motion-based wake requires an unsecured lock screen (no PIN, pattern, or password)
Some devices may need additional system-level configuration for best results
