Leaf Spy Pro is a specialized diagnostic tool designed for Nissan Leaf electric vehicle owners. This application enables users to monitor crucial battery information and other vehicle data through an Android device with Bluetooth, paired with a supported ELM327 OBDII Bluetooth adapter. With the introduction of Bluetooth 4.x LE support in version 0.39.97, users can now benefit from improved connectivity and reduced power consumption.

The app provides detailed insights into battery health, including voltage readings of each cell pair, temperature sensors, and battery capacity metrics. Leaf Spy Pro goes beyond basic monitoring by offering advanced features typically accessible only to dealers. These include adjusting door lock settings, reading diagnostic trouble codes, and managing tire positions after rotations. Whether you're a tech-savvy EV owner or a professional technician, Leaf Spy Pro delivers essential tools for maintaining your Nissan Leaf.

Leaf Spy Pro stands out with its comprehensive feature set tailored for Nissan Leaf diagnostics. The app displays critical battery information such as individual cell voltages, temperature readings from multiple sensors, and the battery's ampere-hour rating, which indicates remaining capacity. It also shows vehicle details like VIN, odometer readings, and charging statistics.

What sets Leaf Spy Pro apart is its ability to perform dealer-level functions. Users can modify automatic door lock behaviors, read and reset diagnostic trouble codes, and register tire positions after changes. The app includes visual tools like histograms for cell voltages and graphical displays for state of charge and battery temperature. Additionally, the logging feature records extensive data into CSV files for further analysis, making it an indispensable tool for both casual monitoring and professional diagnostics.

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 and 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. The introduction of Bluetooth 4.x LE support with adapters like LELink enhances this precision through improved connectivity and reduced power consumption.

For owners, this accuracy translates into actionable insights, allowing them to maintain their vehicle's health and optimize its performance. With features like a resettable energy usage meter and graphic displays of SOC, GIDs, and DTE, users can make informed decisions regarding their driving habits and charging routines.

Despite the technical nature of the data it presents, Leaf Spy Pro maintains an interface that is both simple and intuitive. Users are not required to have any specialized knowledge to monitor their vehicle's diagnostics; the application is designed to be user-friendly for all levels of expertise.

Key information is displayed in an easily digestible format, using graphs and histograms for visual representation of complex data sets. For instance, users can quickly interpret battery cell pair voltages or view a histogram showing the distribution of these voltages without needing to understand the underlying technology.

Furthermore, additional functions available in the Pro version, such as changing automatic door lock settings or reading Diagnostic Trouble Codes (DTC), are accessible through straightforward menus. This ensures that even advanced features, typically requiring a visit to the dealer, can be utilized with ease by the vehicle owner.
