Smart PIR Motion Sensor: WiFi Motion Detector with App Notification Alerts, Wireless Contact Sensor for Home Security and Smart Home Automation, No Hub Required, Compatible with Alexa

I wanted something to turn on and off a monitor that displays security camera feeds. Previously I had the monitor on 24/7, but this is hard on the monitor for the long term and a waste of power when nobody is even there to see it, especially all night. I wanted the monitor to come on whenever somebody is in the room, but turn off when nobody is there.This was inexpensive and ideal. Easily added to the Smart Life app. Then it was easy to configure it to turn on a smart plug (into which the monitor is plugged) when motion is sensed, and turn it off it has been 30 minutes since motion was sensed. There is a variety of timing options; I may adjust the timing but this works good for my purpose for now.It is very sensitive, I have it on the desk near the monitor and if I wave my arm from across the room, maybe 20-24 feet away, its enough for it to switch on the monitor.

The motion detector works as advertised. With my setup, When motion is detected, it works through Amazon to function a routine. After motion is detected, it turns on a light, waits 3 min, and turns off. The response to activate switches / lights is delayed. I’m nearly to the bottom of the stairs before lights are turned on to a 25% dim.I would recommend.

Works great once I got them to work.

The mobile app asks for your Wifi password, to presumably add the sensors to your network. But then it does nothing... no confirmation that you entered it right, no nothing. Not even an attempt to log into your wireless. I checked my log files on my network. That seems very SUSPICIOUS. Anyway, yeah, these are not actually Wifi motion sensors, because they seem to have no interest in using wifi.

Work extremely well and was easy to set up. Battery life needs to improve. Works with Alexa and easy to set up alarms and control lights.

Works great! My dog doesn't whine, bark or scratch to come back inside but he'll come up on the porch and just sit there. This lets me know when he's up on the porch and ready to come in. Was super easy to set up with SmartLife. Turned off the 'no motion' alert. Sends a phone notification and I can customize the notification sound. If you want it to text you, it costs a subscription fee but why the need for a text when it sends the phone notification?

Super easy to set up with Tuya or Smart Life app. Direct connections to WiFi router is nice (no Zigbee hub needed). I just got this sensors so I don’t know how long the batteries would last, but it uses 2 AAA batteries so it’s easy to replace them. The only downside is that the sensor takes up to 3 to 5 seconds to relay the devices that are connected so when I enter a dark room, I have to wait up to 5 seconds to turn on a light automatically. Up to 5 seconds is acceptable so I am satisfied.

It is as expected drops out quite a bit but does the job
