I use Heimdall too, with a bunch of other things. One of them is Pihole.
Pihole will not only help blocking ads at DNS level, it will also work as DHCP server and resolve localy configured addresses, like homepage.ourhome.
Put it on your network and disable the DHCP feature in your WiFi router/firewall (you may need to explicitly set it to forward DHCP to Pihole).
One warning, do not set up names like host.local. the TLD .local is reserved it will cause issues.
If too many people do this, you bet “smart” TV peddlers will start bundling cellular modems on their devices, so they can connect directly to their servers without relying on your WiFi, just like car companies do. Blocking this would require enclosing the TV in a Faraday cage.
