The Raspberry Pi Automation Platform
Edge PID, recipes, compliance, dashboards, and alerts — pre-integrated for a Raspberry Pi you already own. Bring commodity sensors; we bring the platform.
Why Raspberry Pi for industrial + commercial automation
Edge compute survives outages
Linux on the Pi runs the PID loop, the recipe runner, and the alerting logic locally. The cloud is for dashboards, history, and team collaboration — process control doesn't depend on it.
Commodity hardware
$50–$80 of Pi vs $700–$5,000 of vendor-specific IoT controllers. Sensors are off-the-shelf I²C / 1-Wire / GPIO modules anyone can source on Amazon or DigiKey.
Full Linux flexibility
Need a custom Python script, an MQTT bridge, or an exec node calling v4l2-ctl? Full Linux means you're not stuck inside a firmware sandbox.
Pick the use case closest to yours
