Sensors/Toggles aren't working, including Power State

[Makyfa]

I've been trying to get this up and running all day today, and it's been driving me bonkers because it feels like I'm so close, but it just won't work completely.

After setting up the plugin in Homebridge, (and once I realized that I needed to add it individually as a device in HomeKit - that took me longer than I'd like to admit to realize), I've been able to get most of the functionality to work (auto populating lists of available Games/Apps, the ability to switch between them, and remote control in the Remotes app as well).

Unfortunately, I can't get any sensors or most toggles to work, chiefly Power states/commands. Strangely the "On" command -does- work, but the "Off" doesn't.

The issue persists on both wired and wireless connections.

Console has been set into the correct power mode, Remote Features has been enabled, as has Digital Assistants. The Authorization manager in Homebridge says "Console authorized and activated." when doing the check state.

From my Mac I'm able to ping the console (Xbox Series X), and that's listed below:

Any help or suggestions on what to try would be hugely helpful. I feel like I've tried everything today. Thanks!

Looks like the console is not available locally from your Synology Station, check network settings on the Synology Station, firewall, ports lock, etc Console need to be pingable from the station.

The more I'm looking into it, the more it seems like this may be a limitation of running Homebridge on Synology natively. I have all ports open, and no Firewall anywhere on my network, so theoretically nothing should be blocked. That's when I suspected that perhaps it was the Homebridge installation itself that was having issues.

I didn’t catch this earlier, due to the color coding in Terminal, but it’s the Homebridge "user" that can’t ping (meaning this plugin as well). I also don’t see how to change settings for that "user"/application (doesn’t show up in the user list, and it won’t let me make a user of that name either, due to a potential naming conflict).

I haven't had issues with any other Homebridge plugins reaching out to their respective devices, making this limitation unfortunately only affect the Xbox plugin.

Woohoo! I was finally able to solve this. If anybody else has any issues with pinging the console from a Synology setup, the solution was to log into the DiskStation via ssh and execute sudo setcap 'cap_net_raw+ep' "$(which ping)", and then restarting Homebridge.

Solution was discovered here: stfnhmplr/homebridge-synology#86

Nice.
