Love it

As a smart home enthusiast I wanted a sensor that would turn on my hall lights when I opened my lounge door. This one was the cheapest I could find on Amazon & works a charm.Yet another app to install, in this case LinknLink. It was all easy enough, the app found the sensor straightaway & easy enough to link the app to Alexa & be able to control routines.The device itself is fairly cheap looking & requires USB power. I put mine approx 1.5 meters outside my lounge door. I find a lot of the time it will pick up the moving of the handle, the door opening & the lights will have switched on before my physical body is in the sensors range.As it worked so well I bought another & this one is setup to turn my office light on, again the sensor works perfectly & picks me up at about 4 - 5 meters away.There can be a delay in routines running but so much of this is down to the home network, internet etc.So great devices, I recommend.

Works as described - no hub needed

The setup instructions look a bit complicated but are easy to follow if you take it steady. I was up and running in 15 minutes. Make sure that your wifi is running 2.4 only as otherwise you might run into problems. The app that you need to download for setup is ok but once I had linked the device to Alexa it is largely redundant. I use the device to switch on lights (via an Alexa comparable plug) whilst people are in the room. If no movement is detected for x minutes the lights go out. All easy to set up in the Alexa app.The detection range seems fine and quickly picks people up in our kitchen which is around 5 metres square even though, to keep things tidy, the unit is in one of the corner cabinets.It’s early days but there is nothing to suggest that this handy little device will not continue to work as it should. I have taken one star off the rating as you do need to bit a bit familiar with setting up devices like this but otherwise no reason not to buy.

Fantastic little unit.. A motion sensor that acts like a presence sensor for next to nothing..

Purchased this to try as it was so cheap.It is fantastic, it's not a presence sensor but a motion sensor with a user definable delay function, this makes it act almost as well as a real presence sensor but for a lot less that any others I could find.So when it is triggered it shows presence for the period of time set then shows the room empty, but every time it is triggered it resets the timer.. The result is pretty much the same as any other presence sensor..The app is good and setting up and connectivity is a breeze. I have mine hooked into home assistant and it controls my display cabinet lights in my home office.. I enter and they all come on.. 5 minutes after I leave they all turn off..Absolutely awsome

Not really a present detector

This device lacks a key feature of the microwave sensor: a proper person detector that measures distance. Instead, it functions merely as a basic motion detector. Don't get me wrong; it works perfectly, but it ultimately serves only as a basic motion sensor.

Highly Reliable Motion Sensor for a reasonable price.

The LinknLink eMotion Wi-Fi Radar Motion Sensor is a fantastic addition to my smart home setup. It’s incredibly reliable in detecting human movement, with excellent sensitivity and accuracy. Easy to set up and use with Alexa.The Wi-Fi connectivity ensures consistent performance without additional hubs. It’s versatile, allowing for advanced automation like turning on lights or triggering alerts.Overall, this motion sensor delivers top-notch performance and value.

It Works Perfect In The Car

I purchased this to use in my car and it appears to work perfect. As I do not have a permanent power supply in my car, I use a 6v battery box with a usb output and lithium rechargeable batteries which lasts for over two days with no issues. If anybody comes near my car it notifies me on my echo and I get no false notifications unless the batteries are running out. The key thing is to have two sets of batteries and change them before they run out. It does not work with power banks as they shut down, probably because the sensors don’t use a lot of power. It is a perfect solution if you park within range of your Wi-Fi router.

Too slow!

After seeing a demo & recommendation by a famous Youtuber (mmm?) I decided to plump for it. So, after a 2 wk wait, was keen to get it going. Setup was reasonably straightforward ( tho' these days I do have my doubts about cloud-based gadgets & the details you have to give out in order to get them going). Reaction time in combination with an Alexa routine was way too slow for turning a light on, but particularly for turning OFF. For whatever reason, it was too slow if at all, in some cases - this was the deal breaker but Amazon was good in handling the situation...better now than they used to be!

Great value but slow

I opted for this to integrate into HA, although not straight forward, as usual the HA forums are great and managed to get in linked successfully. thats the good bit. Now the bad, the response time is slow for this type of sensor(between 3-7 seconds) and also doesnt seem to detect if I am in the same room and not moving alot.The idea of a 'presence' sensor is to detect presence, this appears to fail on that level. The sensitivity is far less than claimed and as for differentiating between gestures and body, this also fails.That being said, if you want a sensor to act just like a PIR then this does do that.There doesnt seem to be a way of adjusting the response time, or the sensitivity. I did mange to get the 'no person detected' time down to 10 seconds though(for testing purposes) in the app. As stated by another reviewer, you do need to TURN DEVICE LOCK OFF in settings and a bit of code to integrate into HA :modbus:- name: kitchen_motion_linknlinktype: tcphost: *** YOUR LOCAL IP ***port: 502sensors:- name: kitchen motionaddress: 802- name: kitchen_motion_no_person_timeaddress: 832Finally, for the price, I suppose it isnt to bad but I wont be purchasing another.
