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

Very easy to install. The kids never close doors. Now, I get a text if the door is left open too long!

Best contact open/closed sensor on the market. New strong signal to hub, utilizes two alkaline AAA battery batteries, runtime of batteries is 2 years,. I have six in service and have not had a dropped signal from any sensor. Also can utilize multiple programming possibilities and notifications.

This is an excellent product, but it is a bit hard to configure. For example, my freezer is in the garage and I sure don’t want to be told every time I open the freezer door, but I do want to be told if the door is left open for more than five minutes. Configuring the 5 minute alert was quite the chore and yet I’m certain that’s quite a common request? so they could’ve given a real example. Also, once you register your email address with the app, you are forced to register a second time on their website. That second registration is really not obvious. Nonetheless, I have bought additional sensors from them

Product itself is great but not getting timely push notifications when door is opened or closed. Only received them when clicking on the application itself. Have sent an email to the company requesting assistance but so far no response. I also have the SmartThings Hub and inotifications are instant and problem-free. I just received an email from the company and they said that there is a bug in the app and theyll be releasing a new one within 7 days Ill keep you posted as to the progress and update my rating as necessary App released this morning and now push notifications coming in just fine. They need to work on their English translations for the alert, but thats a minor issue. I hope this company succeeds they have awesome products!

Long battery life, Ive had it for two months +

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.

I bought he leak sensors and a window/door sensor. The hub and sensors were very easy to install. I plugged the hub into my wifi router and it activated within a minute, I paired the leak sensors and tested them, they alarmed as soon as I put them in water. The door sensor on my garage doors gives me peace of mind when I am not home, it sends an alert to my phone every time the door open and when it closes.

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).

Convenient and useful, works great.

The whole feature of this device/service is the reason why I originally got it and now it’s being taken away. The SMS alert helped me sleep at night because I would save it as a contact and assign it a very loud alarm as a text tone when the door/window opens. So I knew when/if I heard this in the middle the night, I know to grab the “boom stick” and be ready. For me that’s what made the product so great.
