IR Blaster is a wide-range IR Transmitter controllable via Wi-Fi using MQTT or HTTP protocols. It features 6 high-eficiency infrared leds that will be mounted on a 3D-printed case. Wi-Fi setup is done using a cellphone: the module uses the WiFi Manager so starts in Access Point mode and you can connect to it for configuring. After configuration is saved, module resets itself and connect to your Wi-Fi. From this moment you can send IR codes over http or over mqtt from the domotic system you like most: I use Node-RED, my friend uses OpenHAB for example.


If you follow the links of the project (both documentation and source code are the same link), there is a lot of documentation on how to program and configure the code, the source code and the STL files you can print for making the housing.
