Why Am I Not Getting Notifications From My Alarm Motion Security App?

Zigbee Monitor Sensor

Episode 1787

Brian from Mission Viejo, CA

Brian has had an issue with an alarm system for two years that drives him nuts. They are supposed to get push notifications in the app, but often they don't. Or one person gets them, and one doesn't. Leo says that iOS can be very aggressive at shutting down background apps. Notifications can also be dialed up and down with sensitivity to not get a notification every 10 seconds when the wind blows. So it could be dialed down too far. If you haven't visited the app in a while, it may just be shut off. Or the company's servers may be down. There's a lot of points of failure there.

Larry is having an issue where the computer he built is suddenly freezing up and not letting it reboot. So he's gotten into the habit of using a bootable backup. But now he can't get the computer to boot back up. Leo says that most problems like this can be solved by just reinstalling Windows from scratch and starting over. But if it's freezing during the boot, then it could be a host of things, including cabling. One key is to wait for the "beeps," or Power On Self Test (POST).

Leo says that could be part of the problem.
