I have an OpenEVSE electric vehicle charger (and yes, for the purists I understand it’s not really a charger) that communicates status and data via mqtt. I’ve got an mqtt plugin and am bringing these data into homeseer and have a device that reports the total kWhr “dispensed” from the charger.
This is total isn’t 100% consistent, in that it resets when the firmware is updated, but my goal would be to log the daily kWhr that are “dispensed” by the charger, and then multiplying by $0.07 would give me a rough idea of our EV running costs. As a bonus it might be cool to compare to similar gasoline prices, since I have an average mi/kWhr from the cars that would ballpark it.
I have have no idea how I’d do this in HS. The energy module seems to have the bones, but my research indicates this is an abandoned feature. My other thought is having a bunch of devices that total each days use, week use, and month use but that seems excessive. Any thoughts on how to get started? I’m moderately technically competent and can muscle my way through JavaScript and similar but haven’t yet tried scripting in HS.
Im on HS in Linux if that matters.
Thanks for for any thoughts/guidance!
