Ember Mug CLI is an open-source command-line tool designed specifically for controlling Ember smart mugs. It provides terminal-based management of your mug's functions, allowing users to interact with their smart mug without needing to use the official mobile application.

The tool offers several key features including real-time temperature monitoring and adjustment with precise Bluetooth control, battery tracking with estimated remaining time and charging status, custom temperature presets for quick one-key access, and RGB LED color customization for personalizing your mug's appearance. It features a beautiful terminal interface built with React and Ink for a modern experience and works cross-platform on macOS, Linux, and Windows.

The CLI works by automatically discovering and connecting to your Ember mug via Bluetooth when launched. It requires Bluetooth to be enabled on your device and the mug to be powered on. For Linux systems, it requires the BlueZ stack, while Windows requires a compatible Bluetooth adapter.

The primary benefit is the ability to control your smart mug from the terminal screens you're already using, eliminating the need to switch to a mobile app. This provides convenience for developers and terminal users who prefer command-line interfaces.

The tool targets users who prefer terminal-based applications and developers who want to integrate mug control into their workflow. It's particularly useful for those who spend significant time in terminal environments and want to monitor their mug's status without leaving their development environment.
