Question about Logitech Harmony Companion

unfortunately the remote control cannot control two important devices of mine. sony ps4 and swisscom bluetv box. why is that and why is there no accessory for it. i find that very bad and i am very dissatisfied with the product purchase. it's insanely expensive and can only control my reciver and the projector, great!?! i hope you can help me with this otherwise the remote control is rubbish
