A physical switch would be a good addition for that purpose. For me it's all done in software. I made a simple app for my phone so I can override the schedule, change the target charge % or force an immediate charge from anywhere in the world. I'm happy to put together some legitimate docs with pics that cover this project. Some of it is pretty specific to my needs and require a 24x7 running server, which probably won't be practical for most people, but I have all that overhead already for other purposes. But I can highlight where people could use some alternatives that would make this more generic. I'll post back here when I've got something together.davewill wrote: ↑Wed Oct 09, 2019 10:09 amAnother idea that occurred to me was adding a switch mounted on the outside of the EVSE, either connected to an input on the Arduino or (if you want to be more failsafe) between the Arduino and the relay, that would override the timer and force the EVSE to be on. That way if you need to charge in the middle of the day, or want to go to 100%, all you have to do is flip the switch.
P.S. I'm sure that a lot of people would be interested to see pictures and code for what you've done. It would be very handy for a lot of people.
I came across this thread early on in my searching, too. If this ever becomes a real product then it would likely be the ultimate answer. Presumably much more self-contained and could be used outside of the home at public charging stations. That's probably the biggest drawback to my solution, it only works at my house. I don't see us doing much public charging so for me it's not a big concern, but may be for others. A CANBUS solution would also not be dependent on having a subscription to the Nissan Connect service and all the headaches that go along with integrating with that API. Hopefully someone develops a product some day.alozzy wrote: I know @mux is very busy with his battery extender business, but I recall him mentioning that "80% charging" can be easily implemented using the "man in the middle" CANBUS device that he designed:

Hopefully he's made progress on that front...
I recall that @dala purchased this device from muxsan, perhaps he could look into what coding would be needed to make the muxsan CANBUS device act like a transparent bridge in all respects, other than spoofing the SOC value.
