Wireless Door Alarm Sensor, Windows Open Alarms WiFi/Zigbee

I moved back home to take care of my elderly mother, who has advanced dementia, depression, and MS which has made her pretty much blind. I live and work downstairs, and while I have 2 cameras set up upstairs, it’s still sometimes hard to keep an eye on my mom and make sure she’s safe (when I can’t get up there to physically see her). Last week, she managed to slip out the front door and walk down to the end of the driveway, before she realized it was too hot for her to be outside. Luckily, she managed to make her way back inside without any problems. To help prevent that from happening again, I have this alarm set up on each door: one from the kitchen to the garage, then the garage service door that opens to the driveway. This alarm is great since each sensor can be set with a different chime. Depending on the order I hear them, I can easily tell if my mom is trying to get outside again, or if someone (like her paid caregiver), is coming inside. I wish I had thought of this sooner!
