YoLinK LoRa Smart Door Sensor Starter Kit: 1/4 Mile Open-Air Range, Door Left-Open Reminders, Text/SMS, Email, App alerts, 5 Years Battery Life, Alexa, IFTTT, Home Assistant

This device is great! It quickly added to my home assistant. I am using it to know when the mail has arrived, our box is way down the block and I hate going to check only to find out it hasn't arrived. The Lora solves this easily. My mailbox is quite a ways away and there were zero problems getting it connected. Can't recommend this device enough.

When I bought it, this pack was cheaper than getting two sensors alone. So instead of the 8 I needed I now have 10. I still haven't found a use for the tenth as they all work great. Haven't had to word about the battery in the 6 months I've had it connected to my Home Assistant. The front door now turns on lights when opened to welcome people home. It also locks the door behind after a delay to allow the loading and unloading of groceries, luggage, or any other activity that sends people in and out of the house regularly. Multiple others discreetly monitor the windows of our house, making sure they aren't open as we are locking up. YoLink is easy to connect to Home Assistant and I'll definitely keep using them for my simple monitoring needs.

Yolink is great. Love the door sensors to let me know if a door gets opened. I keep them on all of my reptile and exotic bird enclosures so I instantly know if there is a problem.

Am using it for in door applications so the 1/4 mile distance is severely reduced, but I expected that. It took some time to get the hub in an acceptable location to be able to monitor all sensors reliably but once set, have had no issues whatsoever. One thing that sucks is that the app isn't giving an audible notification when alarm sounds, but it may just be user error. Look forward to investing further into the system to cover more areas

I've been using YoLink for years, and love these door sensors. They provide me with peace of mind knowing when or if my door was opened while away.

Need to be able to install flush. Might need shims to accomplish this.

love this to ensure our doors are shut. easy to use and the app is nice

I started with the speaker hub and have been adding sensors. Like these door sensors and The fact the app will announce what door opens

I don't like that for how much it cost it doesn't have a speaker on the main hub unit I don't like how hard it is to install

The support is just awful. Should not be on the Walmart site without better support.
