Span is a smart electrical panel designed to modernize your home energy system.

With Span, you can control and monitor every circuit in your home from an app on your phone, so you can understand how your home is sourcing, storing, and using energy in real-time.

Reduce waste, automate usage, control circuits from anywhere at any time, reduce utility charges, and optimize backup power and EV charging all in a single package.

The Lumin Smart Panel attaches to any electrical panel to make ordinary circuits smart. Accessible anywhere using the homeowner's app, it allows control of up to 12 circuits in addition to providing insights into your energy consumption.

When paired with solar and energy storage, Lumin optimizes the entire system by keeping watch over backup power and ensuring you have power when you need it in grid outages.

Sense makes homes more insightful and less wasteful. As Sense tracks your home’s energy, it begins to recognize most appliances and other devices that use more than 60 watts. Your home can tell you a lot and Sense is finding new ways to provide visibility to what’s happening and hiding.
