Adjusting charging amps remotely?

[BobbyMartin]

I did a lot of the work myself, but I had a lot of help from a friend's notes on the subject. One thing I didn't do was put the iBooster in. Someone else did that while I was working on other things on the car. Not a lot of other links, but you can take a look at my off grid setup. It's coming down in two weeks when I move to Oregon. All the batteries or LongDog Powerplant

I have a small solar system that charges L1 nicely. Problem is I need to back down on the charge rate when a cloud comes over. It seems logical to do this through software but Elon choose not to allow this. So based on the conversation on this thread I will proceed with the openEVSE route following the programming and hardward these guys have set up for RV camping linuxkidd/ev4rv When I get my system working I'll share all the details. It works now but just the automatic variable charging rate doesn't work. On clear days I don't need to adjust it. Maybe I should go ahead and make a video on my system which cost less than $2000 as a DIY to put my tesla 100% on sunshine power.

I can certainly agree that a video would be awesome!

There is a project on another thread here about using a raspberry PI zero to act as a "master" in the gen 2 HPWC units. The PIzero then connects to a MQTT server in your house that instructs it what the max current draw is. All you then need is the solar inverter to tell the MQTT server what that max is. No need to involve the car... do it by contorlling the HPWC. The thread is something to the tune of HPWC communication protocol.

Personally I prefer the OperEVSE compared to HPWC as the HPWC protocol changes when Tesla feels like it and you have no control over that. With OpenEVSE we control when things get updated and changed.

I read the WIKI and it is nicely documented, good job!

I'm originally from Florida, but yes, I came to Oregon because of my job.

I asked for that, once more. Maybe you want to support ..
