I am new to all of this and have very little knowledge of how these devices work. I am trying to use my Sonos speakers to act as an alarm when my door is opened during night and away mode. For some reason I can only get it to work once and then it never works again. When I activate it manually from the Labs section it takes about 2 minutes to respond but it eventually does. Most of the time that is. The weird thing is that I can use the sonos to announce that the door is open in home mode and it works every time. I have tried deleting all of my speakers and doing a re-install but the same thing happens every time. Any suggestions?
