YOLINK LoRa Smart Door & Window Sensor: Up to 1/4 Mile Open-Air Range, Door Left-Open Reminders, up to 5 Year Battery Life, Alexa, IFTTT, Home Assistant

Easy to install and its portable. Alexa integration is quick and easy. Fast response time.

I installed this in a medium-gauge steel mailbox 125 feet from the hub which sits inside a wood frame house. Despite reading a very weak -120dBm signal strength in the app, the sensor triggers correctly every time the mailbox is opened. The app is superb, allowing you to define what aspect of the event triggers a text or email: opening, closing, or being open for a specified length of time. You can pick whether to get text, email, neither, or both. For tech geeks, this merits 6 stars. Ive also got the excellent leak sensors.

Convenient and useful, works great.

I purchased this device because my husband kept leaving our front door opened. Can you imagine how frustrating that would be? So after looking at many of the available options on Amazon, I decided on this one. Customer service was incredible. They sent me instructions on installation and we’re extremely responsive to my questions. They have a YouTube channel that walks you through installing everything as well. They even walked me through enabling Alexa with my device. This device was very easy to install, but the best part is, it works like magic. Both my husband and I get alerts on our phones when the door opens and closes, and Alexa also chimes in! This was an incredible find, and I am so happy I made this purchase. No more opened door! I highly recommend this product for home security.

I have a ton of these in my home that I use for presence detection to control heat and lighting. They pair immediately, and the app works well. They also have good support from their employees who Im currently in an email thread with to learn how to use their API. Overall I would highly recommend!

Easy to install. I made my own bracket Connects easily and is reliable

So I got into the YoLink LORA to get notifications from a mailbox about 200-250ft from my front door. Its a direct line of sight from there, but I started with putting the hub in the basement at the equipment rack. I figured if it didnt work there I could move it closer to the front of the house. I had no issues with range. The sensor will reliably work through a handful of walls, across the open field, and even from within the all metal mailbox. I have no doubt that without walls and a clear line of sight, 500ft would be simple. I actually think that the 1/4mile (1,320ft) advertised range might not just be marketing fluff. So far Im very pleased with YoLink. The app is easy to use, setup is dead simple, and the range is unparalleled.

Ive asked this question of the manufacturer and on this Amazon page and am awaiting an answer. If this isnt possible I may give it 3 stars. The pros: - Extremely simple to set up (I used wired ethernet connection to my router) - Door sensors can be up to 18mm apart and still be considered closed, so my weird door frames were no issue. - App is simple - Alexa and IFTTT integration available and seamless (though not very good for my purpose) Cons: - Only 1 sensor can trigger one or multiple devices. Multiple sensors cannot trigger the same device with a single command. I want ANY door that opens to trigger the siren device, and I want to be able to enable/disable that with 1 click or 1 Alexa voice command. This is not possible as far as I can tell. I would have to have separate automations for each sensor to trigger the alarm if opened. The only saving grace here is that you can set up specific hours that the automation is active. So Ive created a separate automation for each sensor that is only active at night, since I presumably wouldnt open doors in the middle of the night. If I so happen to open a door during these hours, I have a special command for Alexa to stop the siren. Without Alexa, I would need to find my phone, open the app, navigate to the siren, and press off. - User guide is very limited (19 very short pages) - Siren went off randomly with no record of the event in the first 30 minutes of using it. Not sure if this is going to be an ongoing issue (though this is not a specific problem for the door sensor in particular).

I was cautious to order because there were not many reviews, but I am SO glad that I did. I cannot recommend the yolink products highly enough. They are incredibly easy to setup, and work flawlessly. Setup: The only issue I had during setup was the wifi did not want to connect. I connected the hub via ethernet to the router and it connected without issue. Once it was connected, I simply disconnected from the ethernet and moved it to the location I wanted the hub and it stayed connected to the wifi. Range: They arent kidding about the range on these products! Our chicken coop is over 400ft from our house, across hills/trees/brush and I have had zero issues with connection. Customer Service: I emailed customer service with a question and received an answer within the same day. Very quick, polite, and helpful. IFTTT Integration is very easy to use and works well, though I have found that I prefer the in-app automation since it there is no delay. I am using the yolink wifi plug to turn on/off a heat lamp for new chicks in the brooder based on an alert from the yolink temp/humidity sensor. If the temp gets too high, the plug turns the lamp off - if the temp gets too low, the plug turns the lamp on. Its working very well. I have had zero issues with the app and have found that it has all the functionality that I need.

Easy to install and reasonably priced.
