Just setup a pi-hole for DNS filtering. I subscribed to a bunch of block lists and then subsequently prevented Christine from loading a site on her work laptop. Seeing as how the network admin is not always home to take care of issues like this, I wanted a way for anyone in the house to disable filtering for ~5 min. There are many, many, many IoT button tutorials out there, with lots of different hardware, so this post will cover light details, please use it for inspiration.
