Is this project dead? I cannot get the site to load. I was going to roll my own version of this based on the particle electron before I found out about this project.

OVMS for the Leaf is very active at the moment :)

Tom Parker wrote some great new Leaf code for the OVMS. All is running well and he even managed to get the remote climate control running!

I did some hacking on the Android app, to have some nice Leaf images and to make it run without Google apps.

You can read the story and find some links and files on my website:

All credit for the code goes to Tom.

Enjoy ...

Is the climate control function accessible in the S trim or only the SL and SV?

I've only tested on Japanese Domestic Market cars but so far the remote climate control has worked on all models prior to the 2016 model year. Models with Carwings or Nissan Connect need to have the TCU unplugged as this interferes with the OVMS's attempt to replace the TCU messages. Models without Carwings and Nissan Connect don't have a TCU and so it just works. Some first generation (2012 and earlier) cars need a small hardware modification to the OVMS and a wire connected to the TCU harness.

In the 2016 model year they moved the TCU from the EV CAN bus to the Car CAN bus and apparently changed the messages it sends. I have such a car for testing but I haven't yet tried to make it work. See the thread http://www.mynissanleaf.com/viewtopic.php?f=44&t=24053 for more detail.

The OVMS hardware is out of stock at the moment, the (hopefully) final prototypes of the v3 hardware are being manufactured now.

Hello everyone :)

Is there any update on the project? :?:
is it reliable?

The OVMSv2 hardware & Leaf support has been very reliable for me. Unfortunately this hardware is no longer available.

The v3 hardware is nearly finished. I have a prototype and have ported the Leaf support over. The v3 platform is much more capable but not quite stable yet. I believe the v3 hardware will be available in March, by which time, hopefully, the software will be done too.

I'm really looking forward to the v3 being available. I was already looking at how to put together a microcontroller and GSM modem for my 2015 S before I discovered OVMS. I'm really glad they're moving away from PIC and to ESP32 as well. Will make it a lot easier to work on (for me anyway) and contribute.

My end goals will be remote climate preheat via GSM/wifi (should be easy on the S it seems like) and sending data to an OpenEVSE to do charge limiting. It would be really ideal if there was a way to start/stop charging or change the charge timer via CAN on the S, to help with charge limiting while keeping climate timer & battery heater running of shore power, though I haven't seen anybody exploring any of that.

I've seen what looks like a few different websites and versions, any idea where to watch specifically for v3 hardware? The main website hasn't been updated in over a year.

I haven't really looked for a way to stop charging once it is started, it's possible Nissan did implement something but if they did, it's going to be reasonably hard to find because it isn't used by their Nissan Connect system. Jamming the CAN bus will probably stop charging but I'm not really keen to do that as it's unclear what side effects it might have.

I'm reasonably certain modifying the charge timers can be done from the CAN bus (and hence from OVMS and similar tools) but I haven't spent the time to reverse engineer the messages.

The best source of information on the v3 production is the mailing list at http://lists.teslaclub.hk/mailman/listinfo/ovmsdev

I'm curious, what are the advantages of using a custom built module over something like a raspberry pi with a usb obd2 tool with a hotspot?
