@David-TP Well, they listen to Spotify thru Sonos... sorry for not being precise. And I do not want to limit that... is that possible?

I do not want childrens use of Sonos to count in overall 'usage' during the day ... is it possible to exclude Sonos from hours of usage in the Deco M9 control filters?

@Alexandre. It worked with method 3 - THANK YOU SO MUCH FOR YOUR HELP!

@Kossie Connected a Sonos unit... still no IP to be seen in the app... only a MAC address?

@Alexandre. Thanks, looking forward to a Deco night ;-)

@Alexandre. Bought 3 previsously-owned M9's a few days ago... probably not been used for years since their firmware is so outdated :). Also, I bought another set of M9's a month ago and they work...
