esp_uMQTT_broker
A lightweight MQTT broker, client, and bridge with scripting for ESP8266, enabling local IoT networks without cloud dependency.
What is esp_uMQTT_broker?
esp_uMQTT_broker is an MQTT broker, client, and bridge implementation for the ESP8266 microcontroller. It allows the ESP8266 to act as a central communication hub in IoT networks, enabling local MQTT messaging between devices without requiring an external broker. The built-in scripting engine adds automation capabilities for GPIO control, timers, and HTTP interactions.
IoT developers and hobbyists building small to medium-scale local IoT networks, especially those needing offline operation or reduced cloud dependency. It's ideal for ESP8266-based projects requiring MQTT messaging with custom logic.
It provides a fully self-contained MQTT ecosystem on a single cheap microcontroller, eliminating the need for a separate broker server. The scripting engine allows complex behaviors without additional programming, and the bridge feature enables seamless integration with cloud brokers when needed.
