Otii is a developer tool designed by Qoitech that simplifies measurement and analysis of energy consumption, enabling energy optimization for long battery life of IoT devices and apps. The Otii solution includes a compact and portable measuring unit, the Otii Arc, and an easy-to-use, comprehensive desktop app for Ubuntu, Windows, and macOS. The Otii UI is intuitive and allows for real time analysis, making it easier to see what drains the device's battery. The Otii Arc acts both as a power supply to the tested IoT device and as a current and voltage measurement unit, allowing for a compact and easy-to-use setup for developers, anywhere in the stack.
