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

Bought one for each door and one for each window. Doors work fine. Cant even install in windows at all. Have normal vertical sash windows. Each sash takes one sensor rather than one for both (thats 2x sensors). There are so many window configurations in my home (vertical hinged, horizontal hinged all with indoor screens). Each type needs custom made spacers for the magnets to be installed. Im making them all but am very surprised that for windows theres not a huge variety of spacers for the magnets, 1/4, 3/8, 1/2, 5/8, 3/4. Sad story for what is great service, tech support. Also alerts are not good. Someone breaks into your home and you get the same phone alert/notification that you get for email, ebay, amazon. Got YoLink leak sensors and siren alarms too. When someone breaks in and they alarm you dont know weather to grab your gun or your plumbers wrench. Not well thought out.

great product - works good - Easy installation

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).

Long battery life, Ive had it for two months +

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

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.
