About this app

Leaf Spy Lite lets a Nissan Leaf owner view detailed information about their Leaf's battery by plugging in an inexpensive ELM-327 Bluetooth OBDII adapter into the standard OBDII port on the Leaf. ELM-327 Bluetooth adapters are available on eBay for around $10-$20 and one is required before Leaf Spy Lite can display information from your Leaf.

Due to a recent cost reduction (and feature reduction) many of the cheap ELM327 OBDII Bluetooth adapters from Asia no longer work with the Leaf and report themselves to be version 2.1. The only one currently recommended is the Bluetooth Konnwei KW902 which still supports all the needed ELM commands to communicate with the Leaf.

Information displayed by Leaf Spy Lite:

* Battery State of Health (SOC)
* Voltage of each of the 96 cell pairs (highlighted if shunt active)
* Minimum, average, maximum cell pair voltages
* Histogram of cell pair voltages
* Battery Temperature readings (4 sensors for 2011/12 models, 3 for 2013 models)
* Battery AHr rating (this will decease with age and is an indication of remaining capacity)
* Odometer
* Number of Quick Charge connections
* Number of L1/L2 Charge connections
* EVSE Max available amps
* EVSE voltage

If you are thinking of purchasing a used Leaf this app can help you learn more about the battery's condition.

Leaf Spy Lite lacks the logging function of the full version "Leaf Spy". Depending on your phone screenshots can be used to save this information before you update to Leaf Spy. Leaf Spy Lite also lacks the Service menu features of the Leaf Spy Pro.

Although Leaf Spy Lite provides an easy and inexpensive way to learn more about your Leaf's battery it also serves as a way to verify if you have a working system before purchasing the full version of the app (Leaf Spy) which display much more information about your Leaf or the Leaf Spy Pro version that adds a number of service type functions.

Using Android 11... Got it to work by downloading app.... then establish Bluetooth to the ELM327 OBD Scanner (which cost only $18).. then I discovered to switch phone off and back on, then turn on adaptor and then turn on Leaf spy lite... and it's been working perfect ever since. The key is to plug into your Leaf socket properly and press the button to turn on the adaptor... otherwise it won't go.

Quite useless as it won't see any of my ODBii adapters, wifi or bluetooth which other apps can see and use. So a quick update, 15.11.20, I bought the recommend LELink adapter and the app still refused to connect, tried an older version of Android and it worked fine, the developer is being very lazy here I feel as this should be compatible with the current version of the OS. I was going to buy Pro but if the dev simply can't be bothered to keep his app updated I have little faith in making that purchase.

Essential app for Leaf owners. PLEASE add an option to have a floating overlay showing climate controls, so Leaf SV/SL owners can upgrade their factory nav to an Android unit and not have to lose climate controls! Would gladly pay for Pro and even an additional fee for this. Right now you can only see climate settings in one page of the app.

What's new

Supports Android 9

On newer versions of Android the first time LeafSpy Lite is run after install you will be asked to confirm three permissions.
* Storage access for saving log files
* GPS location to save location to log file if enabled.
* Read Phone status

Bug fix that caused app to crash if "BMS" was selected for the Model Year

Testing new "ELM Assist Mode" in Settings/Options.
Report back if this new option allows your ELM OBDII adapter to connect to your Leaf.
