I assembled a Raspberry Pi and used the DIY method to install the HOOBS software: https://support.hoobs.org/docs/5e875b610ab68b0344e872c5
HOOBS takes all of my non-HomeKit IoT devices, and makes them HomeKit compatible. There are plugins for Nest cameras, game consoles, streaming boxes, Ring doorbells, Rachio sprinklers, anything under the sun, you name it! If it's IP-addressable, chances are there's a HOOBS plugin for it: https://plugins.hoobs.org/search/aG9tZWJyaWRnZQ
Anyway, with a HOOBS plugin for Channels, there are so many things we could do, very easily with HomeKit automation, like "if someone rings the doorbell, pause the TV." Or "When I tap play, dim the lights, and when I tap pause, brighten the lights." Or even just give us an easy button in HomeKit to quickly toggle closed captions. Maybe make them automatically appear when the volume is quiet? The possibilities seem endless.
So this is a feature request for a Channels plugin for HOOBS (and maybe its compatriot, homebridge?)
