You'll receive a timeline notification if we've detected a problem with your voltage readings.
This alert was designed to alert the end user to a possible loose connection in the power cable. Sense was designed for the split phase 120V/120V electrical systems common in the United States & Canada, and is expecting to see around 120V on each of its live power contacts. In regions where single phase 240V electrical systems are common, Sense may display this error due to seeing voltage on one live leg of the power cord but not the other.
Sense may also present this error message if it detects less than 110V on either line of a split phase system.
If you see this error, please contact Support if you have any questions or concerns.
We highly recommend you contact an electrician to check connections or do any work in your electrical panel.
