You'll receive a timeline notification if we've detected a problem with your phase readings.
We've noticed that your Sense power wires are drawing from the same phase of your electrical panel. It's possible that the power wires were either installed on a tandem breaker or, if you installed on a 240V breaker, Sense is sitting on two slots that occupy the same phase of the panel.
While the 240V breaker does ensure that it draws power from two different slots on the panel, depending on where it is placed, those two slots can be drawing from the same phase. To put it into perspective, this is what the phase pattern of the left side of your panel could look like:
phase A
phase B
phase A
phase B
phase A
phase B
phase B
phase B
phase B
If your double breaker is attached on a spot where the phase repeats (consecutive phase B), such as towards the bottom, you may run into this issue.
To find your phase mapping, please consult the specifications for your panel or reach out to an electrician.
We highly recommend you contact an electrician to help resolve this issue. For questions, please reach out to the Support team.
After this issue is resolved, you should conduct a full data reset via Settings > My Home > Sense Monitor > Reset Data. This will clear all historical data and learned devices from your account. However, this will allow device detection to begin with a clean slate and will allow a more accurate detection process moving forward.
