In addition to extensive in-house testing, the Sense monitor has been tested to UL and IEC standards for safety, and certified by ETL/Intertek as safe to install in your home. Intertek is a Nationally Recognized Testing Laboratory (NRTL) and the ETL mark is functionally equivalent to the UL mark.
Sense, if properly installed, also meets all requirements laid out in the 2017 National Electrical Code (NEC). This means the Sense Home Energy Monitor has been through an extensive set of industry standard safety tests to ensure that it is safe to use when plugged into electrical power and safe to use inside an electrical panel.
Sense also meets FCC Class B standards for electromagnetic interference. All electrical devices emit electrical “noise” (in fact, the electrical noise emitted by the devices in your house is one of the things Sense uses to identify them!) — and the FCC has a strict set of limits and requires extensive testing to make sure they are not exceeded. Sense has passed those tests and should not cause interference with other devices in your house.
