homebridge-raspbian-image VS homebridge-apple-tv-remote

Following this guide on the repo, I am running into this warning: [deCONZ] warning: not a deCONZ gateway

For anyone new to this game: Homebridge is far better and far easier than HOOBS to maintain over the long haul, regardless of HOOBS marketing insisting otherwise. And don't just trust me on this, ask any popular plugin developer.

I just image it with rasberry pi imager using the homebridge instructions - https://github.com/homebridge/homebridge-raspbian-image/wiki/Getting-Started.

It has RTL8152B. The doc for raspian HB image here https://github.com/homebridge/homebridge-raspbian-image/wiki/Supported-Raspberry-Pi-Models

Which is different from Ring's Doorbell, but the fact still remains, Ring doesn't have a smart watch app, nor is it natively HomeKit compatible. However if you set up Homebridge for it, you can make it so.

The same Raspberry Pi that Homebridge is on, I'd imagine. It's included as an extra package in the official installer image: https://github.com/homebridge/homebridge-raspbian-image/wiki/How-To-Install-AdGuard-Home

As for the original issue - you may have downloaded a corrupt image - if you really want to use their image (rather than build the OS then install) download it from here but check the sha256 of the downloaded file before using Etcher. I use QuickHash on my Mac but other programs exist for all platforms.

This is an evolving resource. But the long and short of it is that as of iOS 15, there isn't a way to condition, or trigger based on play/power state of an AppleTV or HomePod. In the past, there was a r/homebridge plugin that did that called homebridge-appletv-remote. But, with TVOS 15, this plugin is unusable without some complex and ultimately worthless trickery as Apple changed the "media remote protocol" (after removing the old DACP implementation too with 14) so basically, unless the dev fixes it, you aren't getting it.

If the AppleTV’ s are on 15, it CURRENTLY doesnt work (I have been battling it since beta started). The dev is aware of the issue, and is currently working on it :) it will take some time to move to that though.

I’ve used this in the past

There is a plugin called Homebridge-appletv-remote. It gives you the ability to control Apple TV play, pause, and power states using HomeKit. This can be helpful to trigger automations based on things like playback state (for automatic theater lights) or to turn on the tv in the morning or turn it off when you leave.
