In addition to extensive in-house testing, the Sense product has been tested to UL and IEC standards for safety. This means the Sense 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. We also meet 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!) — 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.
