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

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

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).

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

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.

So far so good. Linked with google assistant and hue. Working well.

Great product and TERRIFIC Customer Service/Tech Support!!!

I buy this with no idea what to expect. It was very simple to install. I am not a tech guy by no means and I love it. Our kids can open the garage door with an app from their phones. We are very glad that we bought it. I am going to buy some for my mother and other family members.

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

Im sold on the Yolink product line. This door sensor was a snap to install and set up alerts on my phone. Im getting a couple more of these as well as their other products.

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.
