Tasmota is a monolithic firmware application for ESP8266/ESP32 microcontrollers that enables local control of IoT devices via MQTT, HTTP, Serial, or KNX protocols. It provides a web-based configuration interface, OTA update capabilities, automation features (timers/rules), and runtime extensibility through the Berry scripting language. The architecture integrates numerous hardware drivers, networking stacks, GUI components (LVGL), audio processing, and cryptographic implementations into a single firmware image built with PlatformIO. Key entry points include the web server for configuration, MQTT client for telemetry/control, serial command interface, OTA update mechanism, and hardware abstraction layer for peripherals. Data flows involve configuration persistence, sensor telemetry transmission, command reception for actuator control, and firmware update streams.
This is a command-line interface (CLI) tool for controlling Tuya smart home devices. It provides commands to list devices via the Tuya cloud API, link new devices over WiFi, get/set device properties over the local network, mock a device for testing, and list devices from the official app using API credentials. The tool is a Node.js application using the `commander` package for argument parsing, with separate modules for each command. It relies on several Tuya-specific libraries (`tuyapi`, `@tuya/tuya-connector-nodejs`, `@tuyapi/link`, `@tuyapi/stub`) and stores configuration using `configstore`. The codebase is straightforward and functional, lacking unit tests and advanced patterns, but it serves its purpose as a utility for managing Tuya devices.
