Nah, I haven't had enough time to try it. I have a 2017 base model leaf now, so it would still be a good project, but I don't think I'll get to it this year.

Thanks. Not nice they charge for it though... I charge at work, where there's open wifi available, and at home, where there's my wifi available. If it just works in those two places I'm a happy camper. Yes, although I'm not sure how much power is available from that LED signal. Plus I think...

Doh - thank you. I'm used to ignoring the sign on the display, and the way I hold the probes. Absolutely I could have been measuring a constant 12V with LEDs that ground it. Whoops. That's great. It is probably a constant 12V that I can use to power the circuit so I don't need to run a wire...

Never mind garsh - I managed to attack the car with a multimeter, and found that: 1. The LED signals are 12V, so I'm going to have to do some conditioning before feeding into the microcontroller. 2. The middle column of fuses in the fuse box are all live when the car is off. So I think I have...

garsh, Can you tell me where to find the Leaf's always-live lines?

I've decided to go with a Spark Photon (also known as Particle Photon). https://www.particle.io/" onclick="window.open(this.href);return false; $19, comes with wifi, easily integrated with IfTTT for notifications etc, simple development environment. Can take 5V inputs, if indeed that's what my...

So I took a look and it's just a ground, and one positive for each LED, driven directly through a 4700F resistor, to the LED with a parallel capacitor. I haven't measured the voltage, but presumably it's 5 or 12. So, I'm in business. Now I just need to figure out how to power it, which depends...

Silly me, I was just looking for the wiring diagrams for the car to see if there was some device that I could talk to with a simple protocol to get the info I need, and I come across this one: http://www.nissanpartsdeal.com/parts-list/2015-nissan-leaf/instrument-meter-gauge.html"...

One thing I'm worried about is the fact the lights are hard to see at some times on the dashboard in direct sunlight, so image processing might have a hard time sometimes unless I stick a dark cover over them, but it might be do-able.... I thought a cover with one sensor per LED might work.

Interesting idea with the phone but I see battery life and lack of notifications as issues.

I am leasing the base model 2015 Leaf without Carwings. I really want to be able to get notifications of when the car is charging, when it's unplugged or finished. My options as I see them are: 1. Try to get Carwings added on. I don't think that's possible though, as I've got the old nav...
