WiFi PIR Motion Sensor for Home Office Security Alarm Compatible with TUYA IFttt

Works great and battery's last long. Even rechargeable battery's last about 6 months.

After chatting with online support, which was not a great experience, it is clear that there is no way to adjust any of the settings for this device. There is no sensitivity setting and the device is slow to respond (4-5 seconds), if you want to use it to turn on lights or anything of that sort. It is probably fast enough for home security. This sensor does not work directly with Alexa, it doesn’t claim to, but I never saw that statement when I was looking to buy.

This motion sensor works. If you have a Smart Life (Tuya) account, it can be used to activate things like turning on lights. I mainly bought this sensor over others because it uses standard AAA batteries, which will be easy to replace.Setting it up is definitely not "plug and play" as so many people are used to, but if you have some initiative, you can get it done. Add it to your devices and create an automation scene to do the work.A few things might help you so you don't have to figure it out the hard way like I did.Since Tuya updated their Smart Life app, it is more difficult to figure out exactly what kind of device to add. There are two PIR devices in the list (Bluetooth and Zigbee), this isn't either one of them. It is called an alarm sensor. It took me awhile to figure this out.Once you have it added, you can create an automation scene where this sensor is the trigger. There are two types of triggers, PIR and 炮兵连. PIR is when motion is detected. You would think that 炮兵连 would be the radiant heat level, but it is not. It is the battery level. There are 10,000 battery levels and you have to set it by scrolling through the numbers, so you probably don't want to make a battery trigger until it gets down to about 10% (1,000), because any more than that will take you a very long time to set.You can create a trigger to turn on some lights when motion is detected, which works fine. You can also add a delay after that and another action to turn the lights back off again. This works, but too well, because the delay is stacked and does not reset when the scene is activated again. So moving around in front of this sensor will not keep the lights on, previous triggers will turn the lights off in a maddening fashion. Just stick with using this sensor to turn the lights on until the technology catches up.There is a Smart Life trigger in IFTTT to activate when a PIR device detects motion. It is called "Person is detected." As of this writing, when you try to set up this trigger, there are no PIR devices to choose from in the list. Perhaps someday this will get fixed. It's faster to do the automation in the Smart Life app, anyway as IFTTT can take as long as 15 minutes to respond.For the price, this is a pretty nifty device for home automation. Poor set up and nonexistent documentation is the price we are paying for being early adopters.UPDATE: Tuya compatible PIR sensors (like this one) are now compatible with IFTTT, so you can now set up applets like adding a row to a Google spreadsheet when the sensor is triggered.

So after fighting with the buggy app and installing the Alexa skill to get it successfully recognized, It won't let me trigger a routine "no devices found.". I even tried to add the pir to a group of lights, no go. I know its working, because the " smart life" app records date and time of the trigger's, but its useless as far as the Alexa app is concerned.Update: Its not detected by IFTTT either.

Bought this to automate smart lights in my maintenance room. Works but very slow response time.Pros,-Cheap-Works with "Smart Life" app-Works on WiFi, don't need a hub (may be part of slowness issue)Cons-Very slow, takes almost a full minute to activate lights.-Does not work with Google home

Download apps, pair it with the motion detector, that is allYou got the alert right away from your phone

The item worked well, too well. We set it up to detect our cat when she wanted to come in. It worked great except that it went off anytime someone came in or passed down the driveway...even leaves would set it off. We decided to go with a different route for the cat. I would have given more stars except that all the different tones are songs except one that is a doorbell. If it would have had a soft chime, we would still be using it for the cat.

The motion sensor was easy to set up initially, and it works well for me with the Smart Life app. Documentaion is sketchy, but I figured out how to define an Automation in the app that pushes an alert on my phone and then flashes a light (connected to a smart socket) when motion is detected. That’s been working very reliably for several days now. But what I wanted to do was integrate with Alexa to announce when motion is detected, using an Alexa routine. The problem is, even though Alexa sees the device (it shows up in the Alexa app device list), it does not see it as a trigger device in the “When this happens” section where a Routine is defined. It just doesn’t show up there.Regarding “check network” failure within the Smart Life app, I’m guessing that it fails because the sensor only connects to wifi when it detects motion, and that the app has no control of that connection. My wifi door sensor also fails that network test, yet works perfectly (even integrates nicely with Alexa to announce that the door has been closed). My smart sockets pass the check network test in the Smart Life app because they are always connected to wifi, waiting to be triggered; whereas the motion sensor and door sensor are the triggers to turn on wifi only when needed to send an alert signal, in order to conserve battery power. Just my guess.Although I am disappointed that the motion sensor does not totally integrate with Alexa in the way I had anticipated (unable to make an Alexa announcement), it does work otherwise. I was able to create voice-triggered Alexa Routines which invoke Smart Life Scenes to enable / disable the motion sensor for/from sending messages and switching on a light (by, in turn, enabling / disabling an Automation within Smart Life). I’ve given the sensor 4 stars because it has been working very well for me. It’s the integration with Alexa, and the sketchy Smart Life documentation that are the main issues.
