Integrate a IR Remote controlled fan with OpenHAB w/ TASMOTA

Discover how I built a smart IR remote controller using a WEMOS D1 module to automate my new BLDC fan. In this video, I’ll walk you through the setup and integration process, enabling full control of the fan through my home automation system using MQTT. Watch to see how you can bring convenience and smart control to everyday appliances!

How to get the IR data from remote control

I have used a TSOP IR receiver sensor to copy the data from the remote of the fan, using an Arduino UNO. For the purpose I have used the Arduino IR Remote library. The usage is fairly simple.

I used the ReceiveDump example sketch to dump the data received by TSOP to terminal. Make sure you are using 115200 baud rate and TSOP is connected to +5V.Please ensure the TSOP data pin is connected to pin 2 of Arduino UNO.

Then you can press the button on the remote and you will see the respective data for the button pressed in Arduino console.

A sample data for a button press.
