The LinknLink eMotion Pro is a revolutionary smart home presence sensor that simplifies your life with its advanced features and seamless integrations.
High-precision Radar Detection
At the heart of the eMotion Pro is 24GHz precise radar presence detection technology. This advanced technology enables the device to sense even the slightest movement and accurately detect the presence of stationary people. It provides reliable data for your smart home automation.
IR Control and Brightness Sensor
eMotion Pro has built-in IR control and brightness sensors, which will greatly enhance the device's ability to implement complex automation operations integrated with presence detection functions.
Flexible Dual-Joints Foldable Stand
eMotion Pro includes a dual-joint foldable stand and adhesive stickers in the package, allowing for easy installation on a desktop or wall. The adjustable stand lets you fine-tune the angle for optimal detection performance.
Smart Home Automations Made Easy
eMotion Pro integrates seamlessly with Alexa and Google Home, enabling you to create routines triggered by human movement, further enhancing your home automation and convenience.
Stay Informed with LinknLink App
No matter where you are, stay connected with real-time notification alerts for detected intrusions or prolonged inactivity. Easily view the event history, export data, and stay informed about your home directly from your phone.
Easy Syncing with Home Assistant via MQTT
No third-party integration needed! Simply utilize the standard MQTT service on Home Assistant and complete a quick setup in the app. eMotion Pro will be automatically discovered in Home Assistant, with its status synced in real-time.

Unfortunately a total failure as a product. Installation was hit or miss, but the real issue is the app which is definitely not ready for prime time. It's not really clear how to set up the zones, and I couldn't see any way to stop it from identifying my ceiling fan as a person and triggering motion status.Very disappointing since I wanted there to be some lower-cost presence sensing options, but this is not it.

Doesn't work 75% of the time with Alexa. As other reviews have mentioned, the power cable is ridiculously short, but that's fixable, so whatever.Where this device utterly fails is in its smart home functionality. After a struggle getting Alexa to even find it at all, it seemingly just worked whenever it felt like it. I tested it in a very small space, on a variety of locations, and while its app said it was seeing me, it failed to trigger the corresponding routine, almost every time. After a couple hours of trying and of using the laughably poorly made app, I decided to return this and the max version that I also purchased.

Initially I was pleased with the eMotion Pro but is has some major flaws.Setting up was simple enough, getting it to work with Home Assistant was also simple triggering automations as expected. The device has 3 sensitivity settings but they didn't seem to make a huge difference - it might be that the area I have it is too small so low works in the same way as high.That's where the good stuff ends though.The mounting system is utterly useless. The sticky mount stickes to a surface fine, but the device isn't securely held in place. I've even tried using double sided mounting tape but there's no real suface area on the back of the device and it still fails. You'll need to 3d print an alternative mount for your device to stop it falling off the holder. Search for "LinknLink eMotion table and wall mount" on Printables.The second issue is far more critical though. Every day this device stops connecting, doesn't renew its ip address and starts flashing its blue light meaning it needs to be setup again. It also means it stops detecting. This isn't a networking issue - every other device including my other ESP32 based ones work fine, renew their dhcp leases without issue. The AP is in the same room as this sensor.Frustratingly close to being a good product but these failings mean I'd have to recommend looking for something else.Current firmware version is v61057

App/install requires GPS location. Although mqtt can be setup to report sensor status, it doesn't report if online.

I really wanted to like this product. Either the people who I watched review this on YouTube were sent a better version or they were full of fluff.The product feels cheaply made. If you're looking to buy this as an universal IR remote, then I suppose it's okay for that. As a presence detector it's not so great. Even when updated to the latest firmware, the features are still saying they're in beta. Which is odd because when looking at the reviews people did almost a year ago, the beta text did not appear in their demos.The convenient MQTT connection to Home Assistant is the only good thing I can suggest about this product. The software still needs a lot of work.

This "Pro" sensor is anything but. The 24Ghz mmWave radar might be fancy, but it's utterly let down by a laughably short cable. I couldn't even position it where I needed without an extension cord looking like an afterthought. And the mount? Don't even get me started. It's flimsy and completely useless for any serious installation. Save your money and look elsewhere for a reliable presence sensor. Connecting to Home Assistant was easy with MQTT but this is not like the MAX.

I was excited to get this device after seeing it on Paul (HOME ASSISTANT!) Hibbert's YT channel. However, after testing it over the weekend in my home office, it has been no better than my existing Aqara motion sensors. It is currently mounted about 6 feet from my desk, about 5 feet high, and facing the side of the desk. It does *NOT* detect small body motions like typing, and certainly not my breathing. It only detects full body motion towards and away from the device. Maybe this is a faulty unit?The set-up process was fairly simple, including the MQTT integration with Home Assistant. I would have preferred not requiring yet another phone app and account; set-up via a temporary local WiFi AP would have been better, with subsequent configuration (zones, settings, MQTT, etc.) via a web interface on the device.Finally, the supplied USB cable is way too short, and should be 6 feet at a minimum.

I would avoid it keeps saying anomaly and won't connect to mqtt
