How do I install Sense?

Sense should only be installed by a licensed electrician. Installation itself is quick and easy, but it requires opening up your electrical panel and connecting current sensors to the service mains. These wires are live, even with your main breaker switched off, and are thus very dangerous. Only a licensed electrician is qualified to work in these conditions.When speaking with your electrician, let them know that Sense is an energy monitor that installs in your electrical panel with two clamp-on current sensors around the mains, and a 240V breaker which Sense uses for its power supply and also to measure voltage on both legs. Unless you have a spare 240V breaker in your panel, your electrician will likely need to provide a new may also wish to share with your electrician this blog post and video to help them get a better idea for what's required:

  • Sense works with split-phase, 120/240v residential electrical panels in the US and Canada. Sense doesn't currently support three-phase or parallel feed installations. Electrical panels with busbars must have enough clearance for sensor clamps with dimensions of 3 6/16"H x 2"W x 12/16"D, and an inside diameter of 1”.
  • Sense connects to your home's 2.4 GHz Wi-Fi network. Because electrical panels can introduce a significant amount of interference, strong Wi-Fi signal and upload speeds are needed near the electrical panel. You may consider installing your router or a signal booster close to your electrical panel.
  • Sense uploads approximately 150 MB of data each day to the servers to facilitate remote monitoring and model building, so it should not be used with a mobile hot-spot or low-bandwidth internet service.
