I’m using the notifications app and I setup a notification saying if freezer go above 5 degrees sent notification to app and speakers. Which all works fine. However the notification are sounding off way to fast like every 30 seconds.
What I want is
Notification to repeat once every five minutes until the temperature went back under or at 5 degrees or a maximum of 5 notifications total.
Your sensor is sending multiple events that are ~30s apart. Each event is triggering your notification rule. You should consider using Rule Machine for this particular notification. Something like this rule:
Don't confuse an additional reporting event as a repeat.
In the context of this notification rule setup here, "repeat" is talking only about the 5-minute notification repeat, not an additional (~30") reporting event.
So I don't think simply unchecking that option will help here -- without a solution like a Private Boolean, then every 30" (or whatever interval) device-level report will still trigger the notification anew.
