Is it possible to use a raspberry as client to HA? I have an extra and want to throw it behind my tv/equipment to run IR and HDMI-CEC and possibly RF. Then add additional at other locations. Would I run a second instance of HA on that device and connect them with MQTT or something like that? Anyone try this?
+1 Good idea, why buy another USB device to enable HDMI-CEC support if we already have a Raspberry? Anyone?
I am kind of doing this using MQTT to communicate between the two HASS.
This is kind of an old thread, but here is the best solution I’ve found
All the device files are written in python so it should be quite simple to create new MQTT broadcasts for pretty much any output on the RPI
