What kind of psyop is bluey running? I’ve been working on this automation for a while myself!
Mine may be a different reason… Our two Porkies (half-pom/half-yorkie) bark at every tiny noise during the day while I’m working UNLESS Bluey is on, if Bluey is on the television in the living room they are quiet as church mice.
The analogous doc for Roku is Roku - Home Assistant and I don’t see anything about randomization. But I also don’t know Roku so maybe you can make sense of channels, and/or searching.
I hope you get it to work, my kid can just click any of these buttons for random episodes and it’s been an incredible time saver. I even wrote a Powershell script that HA calls when a library count changes (meaning I added a new show or removed a show) and then it interrogates Plex via its API to build a new Lovelace yaml that updates this screen dynamically. “Dad can you download Bill Nye?” I just queue it up in Sonarr and then it shows up on this screen with art all by itself 10 min later.
