Graphs of Utility Voltage for detecting issues


Did anything ever come of this? I am curious for an update from Sense on any voltage or other power quality features. Sampling at 1 MHz offers a lot of potential.

I have had LED lamps going out prematurely and it would be helpful to know if I just happened to get a high rate of lemons–across two different manufacturers–or whether I have another problem :frowning:


@eric2 since your friend is at the end of his utilities grid line and you suspect an issue with the transformer size feeding that line, have you considered a whole house surge protector? it would at least save his electronics…


Funny you should mention that… :wink:

I am headed down there in a few weeks to install one (or several). Right now the debate is how many to install. There is one 400a panel with three subpanels. Debating whether we should install them in just the main panel, or in all the panels.

Having them in all panels gives more paths to dissipate current and some level of redundancy…


I’ve tapped into the voltage and overall watts to create these - updated every 30 seconds and stuffed into an RRD. The data is in the API for sure… Just not historical.

Haven’t trended enough to know if it’s useful or not. :slight_smile:


@Dave Hey that’s sweet. Would you be interested in sharing your code and configuration? This sounds like a perfect job for one of my 20 raspberry pis.


I agree that this would be a useful feature. Perhaps to be enabled in settings by more advanced users, since the basic users may find it confusing / not useful.
