Youtube "Kill Switch"

Hello all,

I would like to make a " Youtube kill switch" to be able to temporarily turn off Youtube in the network when the kids have to study.

Anyone here build something like this before? I have a Pi hole and ubiquity equipment running.

Does anyone have any ideas how to control this from Homey?

Thanks!

Adguard in combination with Home assistant works.
Adguard with Homey out of the Box, no clue?
