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 repository provides a custom firmware and backend system for the Sonoff NSPanel smart touchscreen switch, replacing its stock interface with a Home Assistant Lovelace-like UI. The system consists of three core components: a Nextion display firmware (HMI files) rendered on the panel, a Tasmota Berry driver that handles serial communication and flashing, and a backend application running as an AppDaemon app in Home Assistant or as a standalone MQTT manager. The backend processes YAML configuration, manages localization across 38 languages, maps icons to Unicode glyphs, and synchronizes entity states between Home Assistant and the panel via MQTT. The repository also includes extensive documentation, CI/CD workflows for building Docker images and validating HMI changes, and integration examples for ioBroker and IP-Symcon. While primarily an application, it contains substantial data artifacts such as translation JSON files and icon mapping tables that support the UI.
TasmoAdmin is a web-based application for managing Tasmota-flashed IoT devices. It provides a responsive interface for device configuration, monitoring, firmware updates, and batch operations. The application features a modular PHP backend with dependency injection, factory patterns, and reusable helper utilities. It supports MQTT-based device discovery, automatic firmware updates via GitHub, and includes a self-update mechanism. The frontend uses Bootstrap 5 and jQuery for a modern user interface, with JavaScript modules handling dynamic interactions and state management.
This repository provides a complete custom firmware solution for the Sonoff NSPanel smart home touch panel, tightly integrated with Home Assistant via ESPHome and a Home Assistant Blueprint. The firmware is built on ESPHome, a platform for ESP32-based devices, and uses a Nextion display for the user interface. The architecture is modular: a core set of YAML configuration files defines hardware drivers (Wi-Fi, display, relays, buttons, temperature sensor) and page definitions (home, weather, climate, light, cover, alarm, media player, utilities, etc.). Optional add-on YAML packages extend functionality for cover control, climate thermostat, TFT upload, and Bluetooth proxy. The companion C++ component library (in `components/nspanel_ha_blueprint/`) implements the communication protocol between the ESP32 and the Nextion display, handles page logic, and fires Home Assistant events via the ESPHome API. The Blueprint (`nspanel_blueprint.yaml`) allows users to configure all entities and customizations without writing code. Prebuilt firmware binaries are provided for quick flashing. The project is actively maintained, with a large community and frequent releases, though it has significant duplication across HMI variants and some deprecated add-ons.
