What is Gridspy?

Gridspy is a web-based power usage monitoring system that you can access from anywhere. Keep tabs on several sub-systems in your building with independent sensors.

How does it work?

Our sensors are clipped onto your existing wiring in the breaker box. An on-site nexus uploads the data so you can log in to access it using any web browser. No router configuration is necessary.
