Actually there is a way of doing everything, but no one will have enough time and nerves. Everything is possible trough the RS232 serial connection and sending direct commands to the serial port, but then you’ll have to attach arduino, or USB to TTL FTDI, wich can communicate to the RS232 and somehow send commands to this module, and then integrate it in Home Assistant … Too much work … You can search if it is possible to send HDMI-CEC commands for changing to specific input (if it is possible… I don’t think so, but you can give it a try).
