I have an alarm set for 7:30am that should play BBC Radio 2. The alarm goes off at the correct time and i get a notification on my iPhone. Some morning the notification just says "Cannot connect to speaker" other times i get "There is no alarm playing" and then on rare occasions i get the the correct message and can stop or snooze the alarm. Even with the two odd messages i can go straight into the Sonos app and stop the music playing without any issue so clearly it can see the speakers. Beam is hard wired through a switch to the router and then play:1's, One and Play:3 are all wireless. The Play:3 is where the alarm is set for and this stands right next to our SkyQ Mini box which acts as a wireless repeater as well so should be a strong signal. Any help/ideas?
