Redigering og fjernelse af inaktive rum i mit system.

Translation from Danish:

I have locations created under my system without active devices, and would like to remove these without deleting the entire system - how?

Response:

Normally, those ‘devices’ are being held in your router’s IP table for it to see if they’re reconnected. If you just wait until your router renews its IP table, the ‘ghost’ Sonos device will go away on its own. Some routers will remove those left overs on a reboot, if you want to try that, it certainly shouldn’t hurt anything, and would actually be a positive for your network.

Svar:

Normalt gemmes disse 'enheder' i din routers IP-tabel, så den kan se, om de er genoprettet. Hvis du bare venter, indtil din router fornyer sin IP-tabel, forsvinder den 'spøgelsesagtige' Sonos-enhed af sig selv. Nogle routere fjerner disse rester ved en genstart. Hvis du vil prøve det, burde det bestemt ikke skade noget, og det ville faktisk være positivt for dit netværk.
