Sony TVs are well controlled via IR of course.
We also have existing Sony TV IP control that we have tested through their 2012 models.
We receive our first 2013 test unit on Tuesday. If they have real power control via IP in this year's models, we should know soon. We have reason to believe there is a chance it has been added actually. If so, it will apply to the X900A, W900A, W802A, and W650A models. The chance that any of the RXXX models have power IP control is almost nil, but whatever changes we make to the rest of the IP control for Sony TVs will likely apply to the RXXX series as well minus power control. We should be updating the compatibility listings with the results and library updates within a week or so.
