The names of the remote controls may not be reused anywhere on your home network, e.g. not on another homebridge instance, not by a computer, by the Apple TV or any other device. They have to be unique.

Feb 25 '18 21:02 grover

I think they are though? any other thoughts?

No other chance. You either have another homebridge running that is broadcasting these same names, another device on your network is already using the names. Every time someone came to me with the above error, that was the case.

Feb 25 '18 21:02 grover

Ya, i named everything gibberish, I even did homebridge fresh install with only this plugin. Still a no go.

Looks like its something to do with my system https://github.com/oznu/docker-homebridge/issues/35

Ill just try in a couple months.

This error occurs if you initially try to configure multiple remotes (it crashes on the second remote that homebridge-dacp tries to create). If you create one remote, pair it, add the pairing details and then create the second (and subsequent) remotes, it works fine.

Worked this out after creating a whole new test instance of homebridge I had no plans of linking to HomeKit, and I only creating one remote for testing, which worked fine. :)

Thanks for the heads up, I'll try to figure out what's causing this. If you happen to have the crash report, could you add it here?

@grover exactly the same crash report as posted by @jausto

This is exactly what I have faced with my setup as well and mentioned in the latest issue.

I had installed the previous version of homebridge-dacp and wanted to update it on the latest 0.9.1 with a complete new Raspberry and a fresh setup. When trying to enter the pin into iTunes either it doesnt accepted the pin or I couldnt even see that the new remote appeared in iTunes. I also tried it as mentioned the previous version just using the name "New Remote Control" which showed afterwards the remote in iTunes but unfortunately iTunes does not at all accept the pin as shown in the Log in Homebridge.

here is a snippet from log:

@BerkTam your crash report is different and should be fixed with 0.9.2, which I deployed moments ago.

I'll keep looking at the others soonish. Thanks!
