    Detect motion and can be used to trigger lights or alarm

    The motion detect works great, I used it outdoor, don’t think I was suppose to, but it’s under the roof so it doesn’t get wet. I use it with my smart lights for security when it detect motion I have it scripted to turn on the flood lights for 4 minutes and then off. Works great haven’t had any issues.

    good for monitoring motion in an internal area with little visibility...

    I ordered these for my mother’s garage as she had someone hack her garage door opener. I installed them on a textured wall with some 3M velcro tape without issue. Pairing them took a few tries with the Tuya mobile app, but it does well with push notifications. You can also set it up to do text messages, which might be better for long-term tracking. Now everytime someone walks through her garage both of these notify her… while this is a much better scenario, it would be nice if you could disarm them for a set amount of time when you know you will be in the garage for some purpose… or even to only have them armed during certain hours. The way that they currently function, they seem to go through alkaline batteries about every 3 to 4 months. There is some tie-in with Google Home and I will be exploring this in the future as time allows… though my mother does not love changes.
    I am currently rating these four stars, as they help to solve an issue affordably, detect all persons in her garage area, and provide my mother some peace of mind. As always, your mileage and preferences may vary…

    These work with my devices

    First thing, Carolyn V. There actually is a button to enable detection to connect to a device. In the battery compartment, look for a small white tab (if you still have the sensor and haven’t returned it yet), with the batteries installed, hold down on this tab, you can feel it move. I use most anything like an ink pen, but most anything, a butter knife, the tine of a fork. Hold that down for about 10 seconds, then try and pair it. Now, I have two of these already. One is in my garage near enough to the house that it still connects. One is in our downstairs basement as added security. It is giving me trouble on my newest tablet and won’t connect at all to the iPhone, but these have worked great in the past. In fact, to the point of annoyance. I just bought my third, to use outdoors in the event of a stacking situation.

    Why they make this motion detector so hard to set up

    I had a few problems with this device 1st one if you don’t set up your account right off the bat you can’t do it later like they say on the app The blinking lights make it very hard to set up With the strange way of putting the reset button also makes it hard

    Six Month’s Battery Life? [email protected]# Ha!

    Very disappointed at the way this unit burns through batteries. I bought two of these motion detectors and also the very best batteries, long life batteries, that I could buy. Both motion detectors will burn through the batteries in around 4 to 6 days. Absolutely ridiculous. I do not think there is possibly something that I could be doing wrong that would make these batteries exhaust so quickly but apparently, I’m going to have to jury rig some sort of power supply to utilize the motion detector. It works well with Alexa, however it’s worthless if you have to feed it batteries a couple of times a week.
