tolviviov Home Alarm System(3rd Gen), 4pack 120dB Alarm Door/Window Sensors with a Gateway, Smart Home Alarm Security System DIY, No Monthly Fee, Phone Alert, for House Apartment Office

My daughter started sleepwalking about a month ago. We were worried that she would walk out one of our doors. We bought these for peace of mind and I can finally sleep without worrying! The alarm on the doors is loud enough to wake us upstairs and I set the alert on my phone to sound even when in sleep mode. They were easy to install and to link to both of our phones!

The hub doesnt control any of the alarms, at least with what i got, so if you want to turn them off via disarm, it simply doesnt work. You need to manually turn them off if you want to disarm them. False advertising. I spent hours and hours truing to get it to work to no avail. Good on you if you can get it working, but im certainly not foreign to electronics, and i still couldnt get it to work. Returned.
