I have a rooted LG WebOS TV. It's really nice. I can ssh into it. It's on a dedicated VLAN which has all LG domains and IP firewalled off. It can connect to Youtube, using a version of the Youtube app with integrated adblocker and sponsorblock. It's absolute superb.
Do you have any recommended links for such a setup? I don’t connect my TV to the network and use it with an Apple TV. But I’m interested to know more on this.
