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.

Cumplen su función aunque darles reset es muy complicado.

These sensors kinda suck. 2 of the 3 seem to have stopped working already, with fresh batteries in them. When they all worked there was about a 6 second delay to trigger, so I could walk into my kitchen, get a drink of water, then the lights would turn on.I also put one in my hallway by the bathroom. I would go into the bathroom and when I come out of the bathroom the hallway light would come on.

Es exactamente lo que esperaba del producto muchas gracias por cumplir 100% confiable!!!

These things are cheap enough but I can't find a way to say how long to keep something on based on each activation.

This little device works well with Home Assistant’s Tuya integration. It tracks motion and can be adjusted so it doesn’t trigger every time a cat walks by (although it does every once in awhile).It’s smaller than many other PIR sensors but doesn’t lack the features. I don’t know what people are talking about with lack of WiFi; mine works just fine and uses WiFi. I’m using the Tuya Smart app however; these use the Tuya platform and can be connected via Tuya. I’ve got this running on localtuya via Home Assistant.I’m going to grab a few more of them, most likely. Much easier to set up than mmWave sensors, and I can afford to put them in every room I need one. I know similar models can be had cheaper but the Amazon delivery/return is just so much easier.

These sensors were simple to setup with my existing smart life app.Range seems to be poor and motion needs to be within 6 feet of the sensor. Also, they don’t work well in dark rooms.They function as intended and will alert you if motion, however, the response time is very slow.The alerts are inconsistent, but if the sensor has not triggered recently then they might get an alert you within 6-10 seconds.Any other immediate motions will not be alerted because it seems like the sensor has a delay or resting period between alerts. If I’m lucky, I’ll see two alerts back to back within 1 minute. Other times it will take longer.These are not good for more detailed monitoring since they are too slow and lack consistency.

I like the fact that it works on replaceable batteries. Works with Smart Life and Alexa without any problems. My only complaint is it takes 3-6 seconds to activate my lights. I placed it right next to my door in my garage so it turns on my lights prior to entering my house.
