Leaf Spy Pro

Before you purchase "Leaf Spy Pro" please be sure to first install the Free version "Leaf Spy Lite" to confirm you have a phone (or android device) and ELM327 OBDII Bluetooth adapter that works with your Leaf. Leaf must be ON to communicate with it.
If you have trouble connecting to the ELM327 try changing the Bluetooth port number by going to the Settings menu. Port choices are 1, 16 and secure. For devices without a dedicated Menu key hold down the Recent Apps key to bring up the menu.
Once you have the Lite version running and telling you about your battery you can then purchase "Leaf Spy Pro" to tell even more about your Leaf..
The Leaf Spy Pro application allows anyone with a Nissan Leaf electric vehicle, Android device with Bluetooth and an ELM327 OBDII Bluetooth adapter the ability to monitor their battery and other vehicle information normally visible only to the dealer. ELM327 OBDII Bluetooth adapters typically sell for $10-$20 on eBay.
