Leaf Spy Pro is a specialized diagnostic tool designed for Nissan Leaf electric vehicle owners. This application enables users to monitor critical battery information and other vehicle data that is typically accessible only to dealers. By connecting an Android device with Bluetooth to a supported ELM327 OBDII Bluetooth adapter, drivers can access detailed metrics about their car's performance.

The app provides comprehensive monitoring features including voltage readings of all 96 cell pairs, battery temperature, state of charge (SOC), and tire pressure monitoring. Version 0.39.97 introduced support for Bluetooth 4.x LE adapters like the LELink, offering lower power consumption and eliminating the need for pairing. These capabilities make it an essential tool for Nissan Leaf owners who want to maintain optimal vehicle health and efficiency.

Leaf Spy Pro offers an extensive range of features that provide deep insights into your Nissan Leaf's performance. The app displays individual cell pair voltages, minimum, average, and maximum voltages, along with histograms for detailed analysis. It also monitors battery temperature through multiple sensors and provides crucial data such as battery AHr rating, which indicates remaining capacity.

Additional functionalities include graphic displays of SOC, GIDs, distance to empty (DTE), and battery temperature with min, avg, max readings. The Pro version adds advanced capabilities typically requiring dealer visits, such as changing automatic door lock settings, reading diagnostic trouble codes (DTC), registering tire positions after rotations, resetting DTCs from selected ECUs, controlling VSP sounds on 2013-2017 Leafs, and clearing P3102 DTC after battery replacement.

Leaf Spy Pro exemplifies core function accuracy by providing precise monitoring of a Nissan Leaf's battery and vehicle information. This includes detailed data such as the voltage of each of the 96 cell pairs, battery temperature readings, and the car's state of charge in GIDs & kWh.

The app effectively utilizes an ELM327 OBDII Bluetooth adapter to access this information, ensuring that users receive accurate and real-time updates about their electric vehicle's performance. With features like a resettable energy usage meter and graphic displays of SOC, GIDs, and DTE, Leaf Spy Pro offers an effective solution for keeping track of one's vehicle efficiency and battery health.

For owners looking to maintain optimal vehicle condition, the app's ability to display diagnostic trouble codes (DTC) and tire pressure for each wheel with low-pressure warnings ensures that any potential issues are identified promptly. This level of detail supports timely maintenance actions, thus preserving the vehicle's longevity and performance.

Despite the technical nature of the data it presents, Leaf Spy Pro maintains interface simplicity and intuitiveness. Users can easily navigate through various screens displaying histograms of cell pair voltages, battery AHr ratings, and other critical stats without needing specialized knowledge.

One of the standout features is its graphic display capabilities, which present complex information such as SOC, GIDs, DTE, and battery temperatures in an understandable format. The visual representation simplifies the user experience, making it accessible even to those who may not be familiar with electric vehicle terminology.

Additionally, advanced functions like changing automatic door lock/unlock settings or controlling VSP sounds on certain models are integrated seamlessly into the interface. These practical controls ensure that while the app is packed with powerful tools, it remains user-friendly and intuitive for everyday use by Nissan Leaf owners.
