While I’d love proper IP control, there is a workable alternative in the meantime. Both the PS4 and later models of the PS3 support HDMI CEC. This means if you’re using a compatible AV amp or TV you can send IP commands to the TV and they’ll be passed onto the console. In my case I’m using a Sony Bravia, but it should work with other TVs as well. You need to make sure it’s enabled first. On the PS4, the relevant setting is in the Settings =>System under ‘Enable HDMI device link’.
The main limitations are that you can’t as far as I’m aware power the PS4 on this way, but o. nce you’ve got it switched on I’ve found it works rather well. I’ve used it in the main menu, store, Amazon and Now TV apps. It should also work fine for disc playback. Precise functionality varies between apps. For example, in the Amazon app the FF and Rew buttons do nothing and you have to use the directional controls to select fast forward and rewind. In the Now TV app, FF, Rew and pause work as expected, but Play doesn’t and you have to press pause again to resume.
Anyway, hope that’s helpful for some people.
