I’m beaten. I have a Vizio V585-H11 and it is listed as HK support, it even says it on the box. But the Apple HomeKit does not appear in the tab extracted from the Vizio home screen where you set it up. The firmware is up to date. Couldn’t it work on Ethernet ?? I ask because in the instruction video, it is written to make sure that your phone and TV are on the same WiFi network. And tips or advice are welcome! Edit: after the TV is turned off, it restarts after about five minutes. After it started, HomeKit was there. I think it needs to do this when not in use.
