Sony Bravia IP driver from RTI is available- but haven’t personally used it. Have migrated away from RTI. What we do now for C4 at least is set a static addy and set a “preshare key”. A while back an update defaulted the key to off, thus breaking control. Additionally- occasional android errors have popped up- cache overflow etc... Have 3 setups controlled via WiFi and work perfectly (knocks on wood) though this is frowned upon.
