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.

Great long range sensor.

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.
