Does Harmony 525/555 support direct select of HDMI on Philips TV?
It depends on whether the TV accepts discrete IR commands for each input. From a quick search on google it doesn’t seem to. If the TV does accept discrete IR commands then they’ll probably be in the Harmony database or if you can find the HEX codes for the commands you could ask logitech to add the commands. Try searching for whether the TV can accept them. One good thing about harmony remotes is that even if the TV doesn’t support discrete input commands the Harmony can still change input for you and keep track of what input it’s on and what input it needs to be changed to (by cycling though the list of inputs).
