DIY HomeKit enabled HDMI-switch
Hi folks, I noticed that there weren’t any commercial available HDMI-switches which worked with home automation software, that’s why I chose to built one myself.
The base of the switch consists of a cheap 4k HDMI-switch with an IR remote. With the help of an IR receiver I recorded the codes and saved them as hexadecimal codes. After that, I chose a microcontroller to use with the project: an esp32-s2. I wrote a little program using the arduino library HomeSpan to send the codes with an IR led to the HDMI-switch. Now I can control my HDMI source device through homekit!
If you have any questions about the project don’t hesitate to ask!
Thats awesome! I did something similar to control my older audio amplifier. It uses a RasPi that pretends to be a speaker over HDMI-CEC, and sends the remote code over an IR LED whenever it receives the corresponding command from the TV. It’s response time is kinda slow but it works!
