## What it is
OpenMQTTGateway is an open-source firmware that turns ESP8266/ESP32 boards (and computers) into a unified MQTT gateway bridging many protocols such as BLE, LoRa, 433/315/868 MHz RF, and infrared. It aggregates sensor data from hundreds of devices and publishes it to an MQTT broker for integration with home automation platforms.

## Use cases
- bridge BLE temperature sensors to MQTT for Home Assistant
- decode 433MHz RF sensors and publish to an MQTT broker
- receive Xiaomi Mi Flora plant sensor data over Bluetooth
- use an ESP32 as an infrared blaster controlled via MQTT
- detect BLE beacons and track their presence
- convert LoRa sensor messages into MQTT
- read TPMS tire pressure sensors and forward to home automation

## When to choose
- you want one cheap ESP32/ESP8266 board to bridge multiple RF/BLE/IR protocols into MQTT
- you use Home Assistant, openHAB, or another MQTT-based smart home hub
- you need to repurpose cheap off-the-shelf sensors that speak non-MQTT protocols
- you want browser-based flashing and active community support

## When to avoid
- your devices already natively support MQTT or Wi-Fi
- you need a non-MQTT integration target with no broker available
- you require certified commercial hardware support rather than DIY boards
- your project is not IoT or home-automation related
