Door Sensor, KASMOTION Wifi Smart Security Magnet Door Window Sensor with Easy App for Home Office,Compatible with Alexa Google Home IFTTT

Absolutely love this invention. So simple, but effective.These sensors are the most reliable ones I've used so far. Nice addition to my home automation setup. I use these on the kids windows and all entry doors to the house. Get's the job done and I love that it includes a temperature sensor as well! I definitely recommend these for any smart home setup.

Sensor was a tad difficult to get to be recognized and registered, but afterwards works on demand. The small body (not the main) didn't seem to fit into my door frame as mine is recessed, found it easy to open and remove the small metal barb inside and implant directly into frame. Works like a charm. Synced with Alexa to announce to all Echo devices when door is opened.

This item was purchased AFTER I found out that my teenager had jumped out the window to sneak out. That won't be happening again because I get an alert every time the window is opened or closed. Super easy to install, no issues. Problem solved (for now).

Absolute trash. Worked on this for over 90 minutes and couldn’t get it to “connect”. Returned for full refund & ordered the one that is slightly more expensive - turns out - same company advertising as different brands but same horrible product.

I don't know why - but my phone finds a device in both connection mode, but device fail to configure. Actually it stops flashing light during configuration mode and just turns off.AVOID!I think it is Tuya model, which they don't sell anymore.

Great product!

i received the replacement and both didn’t work. it won’t connect to my phone or wifi

This is definitely everything advertised. It's small, comes with tapes to stick as well, very easy to install. Just what we wanted. We affixed 10 of these all around the house - doors and windows. If you want everyone in the area to know a door's been open, you've found the right product.
