When you connect a new device to a 'smart' tv, you must pay homage to the manufacturer with a ritualistic dance. Plugging and unplugging the device. Turning them on and off in the correct sequence like entering a konami code.

Every time you want to switch devices, the tv must scan for them. And god forbid you lose power, or unplug something. You are granted the delight experience of doing it all over again.

I have fond memories of the days of just plugging something in, and pressing the input button. Instant gratification. It was a simpler time.

What is some other tech that used to be better?

Just don't connect your TV to the internet and plug in a raspi. All the "smart" you could ever want without the bloat

Is it possible to connect an Ethernet cable to my TV, but only have it connect the local network, not the Internet? I.e., just a LAN connection. I have very little desire to watch YouTube on my TV, but I do have a personal Emby server that is not connected to the wider net but is accessible locally.

If your firewall can set outbound rules, and you can control DHCP on your network so that you can reliably know the TV's IPv4 address, you can block the TV from reaching beyond the local network there with a "deny all from source address of TV" type rule.

If your router/firewall is handling IPv6 though, it gets a lot more complicated, since the TV could have any number of addresses that change often.

Okay, I checked, and as far as I can tell (which doesn't mean much as I don't know much about this stuff, mind you) it does seem like I can control outbound rules. However, I don't know how to find out the IP address of the TV. Additionally, I don't know if my router is IPv4 or IPv6 in this context, but according to the online spec sheet for my router model it supports both.

There should be a section in the configuration about dhcp, which is how ipv4 addresses are given out on your network. What happens is when a device first connects to the network, it sends out a broadcast with its mac address - the dhcp server (in this case, your router/firewall) hears this, and sends back a reply allocating an address. You should be able to see a list of currently allocated addresses, and hopefully configure reservations to make those allocations permanent. To reserve an ipv4 address for a specific device, you need that device's mac address.

Each item on that current allocations list should have a hostname, a mac address, and an ipv4 address. If it's not clear by the hostname which device is the tv, you can look up each mac address and deduce from there (the first part of each address is unique to a specific manufacturer).

Once you have an ipv4 address reserved for the tv, you can set your outbound firewall rule to block it.

Ipv6, as I mentioned, is much more complicated. It might be possible to disable it completely on your router, and that's likely the only way to block the tv from using it, but then your whole network will lose ipv6 capability across that boundary (probably not a lot of downside to that, though).

Good luck!

Thanks. Will check out my router settings and respond back later tonight. :)

That's the thing though it isn't. I don't need my TV reporting back to the mother ship how often I slug on the couch

Oh it's fuckin nonsense. Which is why you run the pi and control what does and doesn't phone home.
