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 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 cell voltage tracking, temperature readings, battery capacity assessment, and various usage statistics. Version 0.39.97 introduced support for Bluetooth 4.x LE adapters like the LELink, offering improved connectivity and reduced power consumption. These capabilities make Leaf Spy Pro an essential tool for Leaf owners seeking greater insight into their vehicle's health and efficiency.

Leaf Spy Pro stands out with its extensive feature set tailored for Nissan Leaf owners. The app displays voltage readings for each of the 96 cell pairs, complete with visual indicators for active shunts. Users can view minimum, average, and maximum cell voltages alongside histogram representations, providing a clear picture of battery health.

Beyond basic monitoring, Leaf Spy Pro offers advanced functionalities such as resetting diagnostic trouble codes (DTCs), adjusting automatic door lock settings, and controlling Vehicle Sound for Pedestrians (VSP) on compatible models. The inclusion of a logging function that exports data to CSV files allows for detailed analysis in spreadsheet applications. These features collectively empower users to maintain their vehicles more effectively while reducing dependency on dealership services.

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 cell pair, battery temperature readings, and the state of charge in GIDs and kWh.

The app effectively utilizes an ELM327 OBDII Bluetooth adapter to access this information, which is usually only available to dealers. With features like a resettable energy usage meter and graphic displays for SOC, GIDs, and DTE, Leaf Spy Pro ensures that users have a comprehensive understanding of their vehicle's energy consumption and efficiency.

For owners looking to maintain optimal performance, Leaf Spy Pro offers functionalities previously requiring a dealer visit. These include changing automatic door lock settings, reading diagnostic trouble codes, and registering tire positions after rotation, thus empowering users with advanced control over their vehicle maintenance.

Despite its technical depth, Leaf Spy Pro maintains interface simplicity and intuitiveness, ensuring ease of use for Nissan Leaf owners. The application presents complex vehicle data through clear graphic displays and histograms that are accessible even to those who may not be technically inclined.

Users can easily interpret their car's battery health and efficiency thanks to well-organized visual elements like the battery temperature graph with min, avg, max temperatures, and a remaining distance meter to critical battery events. Such features allow for quick comprehension without overwhelming the user.

Furthermore, Leaf Spy Pro enhances user experience with straightforward navigation and interactive components. Whether it's monitoring tire pressure or logging GPS location data into CSV files for analysis, the app provides an unintimidating platform for managing intricate vehicle diagnostics on Android devices.
