It would be useful (for me, anyway) to have a data field with peak instantaneous use along with the date and time of the peak. This would be much easier to use than scrolling back through months or years of notifications. A list of running devices and their draws at the peak would be useful, but I can see some programming challenges.
My context is that NEC calculations show that we would have to upgrade our service from 200 Amps to 400 Amps if we replace our pool heat pump and add an EV charger (or two). So far Sense is showing our actual use to be far below what the NEC calculations would indicate, but a specific peak value would be very useful in deciding whether we will need to upgrade our service or not. (Which in turn could even factor into our decisions about purchasing electric vehicles.)
An electrical contractor told me that quite a few people are preemptively upgrading their service when adding an EV charger. Having definitive information about peak usage might enable people to avoid this expensive service upgrade and also facilitate their decisions about buying electric vehicles. These benefits could be added to the Sense marketing material.
(It would also be useful, and a simple bit of additional programming, to also have a data field with peak solar output or dedicated circuit draw.)
