:bug: "address collision" error with two Xboxes

[chris-araman]

Great work on this plug-in, @grzegorz914! Unfortunately, the 2.0.0 release seems to have broken my environment.

After updating to 2.0.0, Homebridge crashes with this error:

[12/25/2021, 12:34:58 PM] Error: Accessory Office Xbox experienced an address collision.
    at BridgeService.handlePublishExternalAccessories (/home/ubuntu/.nvm/versions/node/v16.13.1/lib/node_modules/homebridge/src/bridgeService.ts:419:15)
[12/25/2021, 12:34:59 PM] Got SIGTERM, shutting down Homebridge...

I have two Xboxes configured. I tried removing both accessories from the Home app, then restarting Homebridge, but hit the same error.

If I remove the second Xbox from my configuration, there is no error, but I can't add my second Xbox.

node 16.13.1 homebridge 1.3.8 homebridge-xbox-tv 2.0.0

Try remove homebridge cashe, remove HomeKit accessory restart HB and add it again.

If I rename ~/.homebridge/xboxTv, I get:

[grzegorz914]

You can not rename this directories.

[chris-araman]

I'm not sure I understand. I renamed them so that I could restore them in case your suggestion didn't work. I have dozens of accessories from various Homebridge plug-ins, so I'd prefer to avoid nuking everything and setting everything back up again.

Which specific directory are you suggesting I remove?

[grzegorz914]

I don't know why You remove or rename some Homebridge folder, here are stored all data from plugins and Homebridge itself. If You not advanced user please use always config GUI.

[chris-araman]

So in order to continue using this plugin, I need to completely wipe all Homebridge state and set up all of my Homebridge accessories again?

[grzegorz914]

I don’t know Your state right now, if your Homebridge and other plugins working correct then not needed Setup all again. If not then Yes. How to install and correct remove Homebridge cashe and correct configure, please use Homebridge Wiki. For configure this plugin please use plugin settings GUI and read readme.

All accessories, including both Xboxes, were working before updating to homebridge-xbox-tv 2.0.0. I'm now updated to 2.0.5. I have read the homebridge-xbox-tv README and am familiar with configuring Homebridge accessories, whether in JSON or using the UI.

I've reset all Xbox accessories using the homebridge-config-ui-x UI, restarted Homebridge, and still see this error when I have two Xboxes in my config.

If I keep only one Xbox in the config, there is no error. I think this demonstrates a bug in homebridge-xbox-tv. If there is additional logging I can provide from debug mode, or any other information I can provide to help you diagnose the root cause, please let me know.

[grzegorz914]

please post your complete config here

[chris-araman]

I've verified that removing or renaming the accessories directory has the same effect a "clearing the cache" in the homebridge-config-ui-x web app. https://github.com/oznu/homebridge-config-ui-x/blob/441fa8b3df6e24dc51b7033a64441e03bd9ed988/src/modules/server/server.service.ts#L262

I've also diagnosed and proposed fixes for the issues I've reported here in #126.
