For most domestic scenarios, one kwikwai plugged anywhere in the HDMI path will allow control of all CEC devices in the system. This same kwiwkai also lets you in on the bus chatter, so a smart HA system can figure out what’s going on: for example, some DVD players notify the bus of play and pause events.
Most devices even answer to status queries (some are defined in the CEC protocol), so you can ask them if they’re on or off, playing, paused or recording.
Quite simply, we’re not sure how one can achieve that sort of control for 2 or more devices from IP for much less, even considering the current currency “crisis” and its negative influence on the USD or EUR price of kwikwai…
And look, ma, no ugly IR sticker on the TV !
