I have a similar setup at home with a Raspberry Pi running PiHole that all the devices on the house network use for DNS. It effectively kills the ads on our Roku TV. I can still see the blank spaces where ads are expected to be, but the spaces are thankfully blank.

@TwoClownsEating @ginger_tosser I am in rented accommodation at the moment and there's a Samsung smart TV here. I have a Mobile Broadband device for internet access.

I took have PiHole running in a Raspberry Pi Zero 2. The TV is constantly trying to call home and, for some reason, to Netflix which we don't subscribe to. The combination of Pi Zero 2 and PiHole comes highly recommended.
