WiFi Door Sensor

This product works really well. I put it on my door and every time the doors open I get notification that the door was open in time. Good alarm system . All you need to do is download app… this is so good. I’m thinking to buy another one for my window.

Very good functionality. I will buy more to others doors.

I have some similar sensors in ZigBee format and they operate as expected. Thought to try the WiFi version at another property. Well these sensors do detect state changes it is very slow, controlled and intentional. When opening and closing doors normally it may detect 15-20% of the movements. The reporting is really slow to smartlife, also once a state changes it takes a long time to report changes. I would not recommend, not too sure f its due to WiFi or what, but ZigBee ones seem fine and show at least 95% accuracy and reasonable reporting times not these.

no longer works after less than 2 years of usage. app is always late to alert.

Excellent item and worth buying

The first device I received wouldn't answer an Alexa question, "Is the door closed?" with anything but "Battery is 100." After some discussion about that, the item stopped detecting open and closed altogether. On Jul 24th at 7:51 p.m., the seller offered to send me a new one. On July 25th at 2:56 a.m., I said yes. On July 25th at 3:17 a.m., the seller messaged, "I have applied to Amazon for reshipment and I expect you to receive it around July 29th." On July 26th at 3:18 p.m., the item was delivered to my front door!The new device detected open and closed correctly, although a question about the battery level gave the same answer with new batteries, dead batteries, and no batteries! The inability to determine that batteries are dead (or have been removed) seems to be overall device makeup, as one I have that looks the same but is a different brand with different firmware does the same thing. It reports the last detected status, so, if the batteries die when the door is closed, it will say the door is closed when it has since been left open.For this reason, I am using it (and soon my different-brand one) to tell me when I've left the refrigerator door or freezer door open and using Ring Alarm detectors for my patio storm door and front gate, as I have three collies, and I need to depend upon correct responses. However, I would certainly recommend these detectors — from seller Gaoducash only — for general use and reminders.

This works just like I wanted. Setup Alexa to say what door opens on select device during select hours, so it doesn’t wake the kids but alerts me. It also goes off on my phone what is perfect because if I’m outside, I can still be notified. It is a little delayed like 20 seconds to say it on Alexa, but not a big deal. Very easy to install, had about 2 weeks now and really like it. The price is great too, was looking at the ring version of this but you have to have ring alarm and they are more pricey too. You do have to know what you are doing when ur setting up Alexa to alert you but it’s very basic in my eyes.

WORKS WITH GOOGLE HOME
