I've searched here and see a number of posts that detail how things work if you have two homes. You basically need to mark one as your "home" and then when you use it at the other it tells you that it notices that you've traveled, but everything basically still works (with the exception maybe that DVR only ever works for the home location). You then need to "check in" at least every 90 days at your home location. Got all of that, I think.
What I haven't seen details on is watching *at the same time* in two locations. My wife and I live in NYC but also have a beach house in NJ. She needs to be in the office in NYC three days a week and I don't, so during the summer I spend most of my time at our beach house in NJ. Will this setup work with YouTubeTV? That is, if I mark NYC as our "home" location, can my wife watch in NYC (including local channels there), while I am *also* watching from the beach house in NJ at the same time? And if so, do I have access to local NJ channels, local NY channels, or no local channels? Basically, it wasn't clear from the discussion of "traveling" if that restricts your access at home while you're traveling.
For anyone curious, the way we handle this now is that we have Spectrum in NYC for both internet and cable TV. They have an app (for both mobile and Samsung smart TVs) that allows you to watch anything you subscribe to. And it works at the same time as live TV at home. So, she watches our Spectrum cable in NYC and I can use the Spectrum app at the beach at the same time. It's actually great. The issue is that we want to ditch Spectrum for Verizon FIOS in NYC, but only use that for internet, rather than cable too, which is why I'm looking into YouTubeTV.
And a related question: if I'm watching on something like my Samsung TV that doesn't have GPS (rather than my phone), how does it know my location? Is it just using the IP address and geolocating that?
