When I was using raspberry pi, I bought a IR transceiver module for Arduino. and used it for several years. IR transceiver
And this year, I am interested in ESP8266, so I bought another IR receiver, IR transmitter.
Install esp8266 and voltage converter on breadboard.
Install IR receiver and IR transmitter in front of tv
Install breadboard below of table
And here is ESPHome Source
I orignally, wanted to install these.
ESP01 is very interesting, but, providing both 3.3v and 5v is somewhat overwhelming?
