OpenMQTTGateway project goal is to concentrate in one firmware different technologies and protocols, decreasing by the way the number of physical bridges needed, and hiding the different technologies singularity behind a simple & wide spread communication protocol; MQTT (opens new window).

Overview

OpenMQTTGateway supports very mature technologies like basic 433mhz/315mhz protocols & infrared (IR) so you can make your old dumb devices "smart" and avoid throwing them away. These devices also have the advantages of having a lower cost compared to Zwave or more sophisticated protocols. OMG also supports up to date technologies like Bluetooth Low Energy (BLE) or LORA.

To have an overview of the supported PIR, door, water, temperature, smoke sensors, sirens, rings, beacons, switches & weather stations you can take a look to the compatible devices list (opens new window)

You can run OpenMQTTGateway on a wide variety of boards (opens new window), ESP32, ESP8266, Arduino MEGA, UNO (with limitation). BLE to MQTT gateway can also run on Raspberry Pi, Windows or Unix computers thanks to Theengs Gateway (opens new window).

With MQTT you can connect the compatible software you want, integrating in home automation controllers like (OpenHAB, Home Assistant, Jeedom, FHEM, Domoticz...) or Internet of Things software like Node-Red.

# Use cases

With OpenMQTTGateway and a controller you can for example:

Monitor a garden with a Mi Flora BLE sensor and control an irrigation valve depending on the soil moisture,
Trigger a fan depending on the temperature and humidity thanks to a Mi Jia/LYWSD03MMC BLE sensor,
Follow your meat temperature when cooking with an Inkbird IBBQ
Alert yourself by a controller notification if the temperature of a fridge or freezer is too high,
Detect a beacon/smartwatch so as to trigger a special scenario when you come home,
Lose weight with the help of a complete log system (opens new window), video from @Andreas Spiess (opens new window)
Detect opened door or windows through 433mhz or BLE and alert yourself when leaving
Detect water leakage or smoke remotely
Actionate a siren if something is going wrong
Detect if your far mailbox has been opened by the postman with LORA
Make smart your old TV or AC system through infrared control
Monitor vehicle tire pressure

The limit is your imagination 😀

# Functions

Behind the scene you will find functionalities dedicated to gateways like:

Deduplication
Simple and lite API
Strong integrations with libraries used
Signal forward/repeat
First configuration with web portal
Whitelist & Blacklist management
Secure connections
Over the air updates

# First ready to go OpenMQTTGateway device !

Theengs plug (opens new window) is available flashed with OpenMQTTGateway, and brings the functions below:

BLE to MQTT gateway, tens of Bluetooth devices supported thanks to Theengs Decoder library. The plug uses an ESP32 acting as a BLE to Wifi gateway to scan, decode and forward the data of the nearby sensors,
Smart plug that can be controlled remotely,
Energy consumption monitoring,
Presence detection (beta).

(opens new window)

Support the project by purchasing the Theengs plug (opens new window) The plug is available in North America only, other regions are planned.
