Fault Detection: Power Quality is an algorithm that identifies voltage dips and spikes in your home. In a split-phase 120/240V electric panel, each leg should sustain a voltage of around 120V. This experiment identifies fluctuations outside of a normal range. If you’ve received a notification in t…

Power company finally came out and it looks like they had an issue on their end (I assume at the transformer). My voltages are still on the high side (~124-126) but they are now balanced across the legs at least so my inverter isn’t tripping.

Just wondering…at what point do the old events past 30 days drop off? This screenshot was taken on 9/20. I’m at about 52 days for my oldest, but still tracked event. [Voltage]

Today sense detected a power quality issue I didn’t notice any different I was just looking around the app [image] [image]

Found out I had power quality issues by looking at the lab. I wasn’t aware we had a problem otherwise. We do that solar and it is split into two sets. Could that be causing any of the issues? [Screenshot 2020-10-09 at 1.09.03 PM]

If your SENSE readings are correct, then you may have a loose or bad connection at the breaker panel. You will probably need an electrician to come inspect and see if all your terminations are tight. Or maybe the SENSE monitor has a bad chip that reads your voltage on L2. Something you might try,…

This has probably been one of the most helpful features from Sense. We’ve lived in our home for over 5 years. We’ve noticed that large appliance turning on caused some light flickering but thought nothing of it. Over the last 6 months, we noticed that our solar panels would shut down whenever we tu…

Hi, Any chance you could make the Volt dips and spikes monitoring for 240V. Yes, I know that Australia isn’t “supported”… but would be an easy tweak for us on 240V (I cant actually see my data as it’s all up I. The clouds of the graph

Would it be possible to also provide “power quality” data for the flex sensor add-ons as well? I have an appliance (Miele TWI180) that intermittently shuts down due to detected electrical faults. After some months of back & forth Miele has replaced the DC motor for the drum however they believe th…

[2020.12.27-Voltage-spike] I registered a voltage spike of 146.7 volts, but there is no indication on my graph. When will SENSE add the feature that immediately notifies the user when a voltage spike or dip has occurred? I also would like to see a graph that you can scroll back through time. I …

This is definitely odd that the graph is not showing the spike here @Dcdyer - can I give Data Science permission to look at your data and see if we can figure out what happened here? [image] Dcdyer: When will SENSE add the feature that immediately notifies the user when a voltage spike or dip h…

@JustinAtSense You have permission to review my data.
