I’ve just ordered my emonEVSE to be installed, so I thought I’d introduce myself on the forum, and ask a couple of questions. I already have an emonPi monitoring my house usage and solar, and I’m in the process of moving to Octopus Agile for my tariff (partly to get cheap power, but also to try to get reasonable export rates when the solar is generating and no-one is home - I missed the FIT and don’t have storage).
So the plan is to automate the EVSE to charge the car during the cheapest period, depending on how much charge the car needs, and when you plan to need it. I have a script already which deals with getting the car SoC (I have an i3 so it talks to BMW to get that) and working out when/ how long to charge using the Octopus API, but I’ve yet to get my head around controlling the EVSE. First pass would probably be just set timers, but I’d like to get to a point where it stopped charging during spikes to continue later, feathered the charge rate in higher priced time periods, and provided power for preconditioning before departure.
At the moment I’m really just trying to find out if other people have done similar things that I use / customise, or if anybody wants to work together on something like this?
