NetHomeServer can use the speaker audio output to send protocol signals for IR or Radio (RF) protocols. To actually send them as IR or RF, you need some kind of additional hardware that can transform them. | NetHomeServer can use the speaker audio output to send protocol signals for IR or Radio (RF) protocols.
