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

Convenient and useful, works great.

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

Great Product!!! You can used on door, windows. Super easy to setup(just scan the code bar). The integration with the HUB its a piece a cake(be sure to buy the hub separately or a combo). You can also buy a siren alarm from this same company if you want any noise for any who tries to enter your place.

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.

Long battery life, Ive had it for two months +

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).

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

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.

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.

Easy to install and reasonably priced.
