Now let’s use this information to emulate a button press from the ESP. First, wire up the RF transmitter to a new pin on the ESP and configure a global remote_transmitter instance:

Recompile again, when you power up the device the next time you will see a new button in the frontend. Click on it and you should see the remote signal being transmitted. Done!

This will allow us to send any data we want via the IR LED. To replicate the codes we decoded earlier, create a new template button that sends the infrared code when triggered:

The axis along which the electric field oscillates is referred to as the polarisation axis. When a light wave possesses many different polarisation axes, it is ...

Now let’s use this information to emulate a button press from the ESP. First, wire up the IR diode to a new pin on the ESP and configure a global remote_transmitter instance:

The remote_transmitter and remote_receiver components can also be used to send and receive 433MHz Radio Frequency (RF) signals. This guide will discuss setting up a 433MHz receiver to capture a device’s remote codes. After that we will set up a 433MHz transmitter to replicate the remote code with the press of a button in the frontend.

Some devices require that the transmitted code be repeated for the signal to be picked up as valid. Also the interval between repetitions can be important. Check that the pace of repetition logs are consistent between the remote controller and the transmitter node. You can adjust the repeat: settings accordingly.

If the codec is already implemented in ESPHome, you will see the decoded value directly - otherwise you will see the raw data dump (which you can use just as well). You have just successfully captured your first infrared code.

If the log output is flooded with “Received Raw” messages, you can also disable raw remote code reporting and rely on rc_switch to decode the values.

In this guide an infrared device will be set up with ESPHome. First, the remote code will be captured with an IR receiver module (like this one). We will use ESPHome’s dumping ability to output the decoded remote code directly.

Compile and upload the code. While viewing the log output from the ESP, press a button on an RF remote you want to capture (one at a time).

This will allow us to send any data we want via the RF transmitter. To replicate the codes we decoded earlier, create a new template button that sends the RF code when triggered:

Compile and upload the code. While viewing the log output from the ESP, press a button on an infrared remote you want to capture (one at a time).

Then we will set up a new remote transmitter with an infrared LED (like this one) to transmit the code when a button is pressed.
