Some troubles, but ultimately – it’s a door sensor
I got this sensor to add to my slowly growing smart home. I like to get the notifications/alerts from devices & to have the devices ‘talk’/react to one another, so this one was another addition.I already have the Tuya app, so getting the sensor added to it was relatively easy. There are often issues in figuring out how to get the devices to be detected, but this one was no different than any of the others, so I was able to get it to connect to the Tuya app.From there, I use SmartThings, so I have all of my Tuya devices linked/imported into my SmartThings app – and that is where the ‘fun’ really happens. Ideally, with this door sensor, I can set up something where if a door is open, it will send a notification & trigger an alarm. I’m still having some trouble with that whole path, but it is detecting when the sensor is open, so I don’t think the issue is on the sensor side.The sensor itself is bigger than what I would have expected. It is not of huge concern based on where I was going to put it, but there are certainly other doors in my house where I’ve put sensors where there hasn’t been so much room – so this one would likely not have fit in that area. Again, didn’t matter for me here, but something to look out for if you have constraints.Overall, I’m happy enough with this sensor.

Works OK but not what I was expecting.
It was easy to connect and easy to add to Google Home. What I mainly wanted it for was to play something like a sound through my Google speakers every time the door is opened but that doesn’t seem to be the case.

Excellent for caregivers
Really smart addition for caregivers. It helps us to know when our elderly mother has opened her door without being intrusive. It’s alway a good idea to know when shes out so we can keep an ear out for her if she needs help since she has mobility issues. Only draw back is I can’t disable the sensor with the app and it really burns through batteries.

Paid Subscription Needed
To work with an automated warning a paid annual subscription is needed.

Simple, Smart, and Perfect for Added Security
This little sensor has been a great addition to my barn setup. It was easy to install and sync with my WiFi, and now I get instant alerts if the door is opened. It gives me real peace of mind knowing no one’s accessing it but me. The connection has been reliable, and it’s discreet enough so that it isn’t obvious. A smart, effective way to keep an eye on things remotely.My only gripe is the directions. They are about the size of a gum wrapper. The writing is ridiculously small. Probably a 2pt font, and they use colored letters like blue and green, which makes it even more difficult to see. Next time, just use a QR code and ditch the in-package directions.
