As per the title, I suspect this doesn't exist. But do any of the HDMI matrix/switcher boxes have an API we can tap into for selecting inputs? I basically want to control and automate over the LAN with a local API rather than having to use an infrared zapper.
(I know an AVR would work for this but I don't want or need one, or the size or the extra power - audio is all handled with a box that already exists, I just want to be able to control more HDMI inputs)
