Notifications Behavior Check - Multiple Devices Used - How frequently do you want to be notified?

Single Notification Rule in Notifications App.

Set notification frequency to 59 minutes for temperature notification from either one of two devices proximal to each other.

Getting notified once by the first device to exceed my threshold, and then a second time by the second device within the 59 minute frequency window (like within 5 minutes of the first device).

So I'm just checking that this was the behavior intended and not that "the first device to trigger a notification sets the frequency clock for all devices selected as triggers".

(I might come back later with a concern that I have seen the notification twice on the first device 10 minutes later thus ignoring the 59 minute clock. But I haven't confirmed that I don't have some rule buried somewhere that I set up awhile back (outside of Notifications) to achieve the same end.)

Post a screen shot of the settings you have in the Notifications app...

AFAIK, if you don't set the "only once a day" flag, you will be notified every 59 minutes if the temp is above 100.

You can also add additional restrictions:
