This repository provides the code for an ESP32 with an appripriate IR transmitter to be used as an alternative remote for this particular HDMI switch: https://www.amazon.de/gp/product/B0881SF6ZK
This primarily resulted from me wanting to hide the switch and control it with my iPhone.
You could also extend it further for HomeAssistant support.
