If you’re just trying to set up alarms, and you have Spike in follower mode working properly, you should be able to go to Settings>Alarms
If you want different sounds/snooze times for different types of alarms (or different times of day) you need to go to “Alert Types” and make those. Then in the Alarms menu select the event you want to set an alarm for (ie “Urgent High”), then hit “add”, and specify the times (and BG value if applicable), then assign the alert type you want for that alarm. Sorry if this is confusing!
My “Alert Types” menu looks like this:
Because I have different Alert Types made for daytime and nighttime of each type of alert. I made them all separate mainly because I wanted differences in sound (my daytime alerts are mostly silent, my nighttime alarms are super annoying and loud) and snooze times (Urgent Low during the day has a 30 minute snooze, while daytime High has a 60 minute snooze). You can name them whatever you want, I named them this way to help me keep track of them.
In my “Urgent High” settings I have two alarms set, one from 0:00-07:00 for my nighttime alarms and one from 07:01-23:59 for my daytime alarms. It won’t let you set two alarms to have the same time so you have to adjust the minutes appropriately to make things work. You can also just set an alarm to function for the entire day by checking the little box.
It’s kind of a lot of effort to get it all set up the first time, but it allows for a lot of customization once you get it going!
