Adies and Gentledoos, it is here. The Good: - It accurately senses *presence*, even when I'm sitting still at my home office - It has all of the features of the night light - It has amazing new features I did not expect! - It is super easy to pair and use The Bad: - It is not a 1for1 replacement for the night light The Ugly: - It might be difficult to find the right place to put it in your situation First off, I asked for exactly this product several months ago in a review of another 3R device. I doubt this is a result of my review, product development takes a long time. But dangit, if it isn't still awesome. If you've seen the night light, then you know mostly what to expect. What's different here is that it does NOT come with an adapter for a standard wall outlet like the night light does. This is USB ONLY. Bring your own wall wart. The USB C power plug is on the back, but not recessed like the night light, so you couldn't easily plug this into a wall even with your own wall wart. tl;dr: This is a "set it on a counter/shelf" product. But it is USB, so you can run it off of a battery or a wall wart or any USB charger or even plug it into your computer. I have mine plugged into my laptop dock. I think this could be largely improved by adding a second USB port to the bottom so you could choose which one to plug it into and, for example, plug it in on the bottom and use a Command Strip to mount it to a wall or cabinet, or plug it in on the back and set it on a bookshelf. This new version has actual presence sensing. The high frequency radar does not penetrate walls, so it doesn't sense motion when I'm walking upstairs. It's sensitive enough that it accurately detects me sitting in my office chair not moving for hours hwil I work (or play games). A new feature I absolutely adore is that you can set an automatic brightness and color mode for the led light, so it changes color and brightness based on the time of day. That is perfect for a bathroom or bedroom that you might want brighter, whiter "night light" in during the day but be dimmer at night. I haven't yet checked for a device-specific driver from 3R, so I think it's using the night light driver right now. I'll be doing that and getting photos over the weekend. But I wanted to get this review up ASAP because I've only had this a couple of days and it's already filled in so many gaps in my home automation that regular motion sensors just can't. And it's zigbee, so I don't have to worry about smsrt devices spying on me, and it's 3R so it literally just works right out of the box. I'm definitely buying another one, and will probably get 3 or 4 more as budget permits. [quick update: This should use the ThirdReality Motion Sensor driver from the 3R channel, which is the same driver for both Smart Motion Sensor R1 and Smart Presence Sensor R2. However, I think there's a bug in the zigbee ID because this is using the 3R Zigbee Switch driver, which the night light uses. Hopefully 3R fixes that soon.] Final question, is it worth the price? At the current $50ish price tag, I think it's a bit over-priced. But if you really need that presence sensor (to turn off the lights in the garage when you forgot), and you really want that LED and the other features 3R offers, then this is definitely an upgrade over the cheaper single-purpose off-brand tuya crap you'll spend weeks fighting with to get a community driver to support. But hopefully you can find this one on sale :)

I set it up in Home Assistant using Z2M. Needed to update Z2M to the latest, and there was a firmware update for the R3 (build 40) that took a while to install. Easy enough to setup. Incredibly sensitive. It can detect me through walls if I crank it. The light is a nice touch, and I like that it doesn’t use batteries. The firmware could use some fixing (or at least some documentation). It comes with 4 adjustable sensitivities: motion (0-20), presence detection (0-20), presence sensor (1-6), and hold time (1-4). I did some testing, and having the motion sensitivity >0 basically makes it unusable. It will only detect if you are within 1ft (not sure if there’s some weird interference or something going on inside the device with it active). Presence detection is more sensitive the lower the number, but presence sensor is more sensitive the higher the number (not sure why). Detection at 1 with sensor at 6 it can see through walls and takes about 1 minute to clear. Detection at 5 with sensor at 6 is the sweet spot for me. It can see me standing at the doorway around a corner 15ft away and clear in about 15 seconds if I leave the room. I live in an apartment with concrete walls between neighbors, so I don’t have to worry about false positives. But something to keep in mind. Lux and TVOC work and are nice to have, but I don’t plan to use them so I didn’t test them against a baseline. TVOC is showing 4,100ppb with windows closed and is slowly climbing. Lux is showing 1,100 about 15 feet from north facing window.

So far I'm pretty disappointed, especially since my other ThirdReality smart-home devices are among the most stable devices I own in the smart-home arena. I have their motion detectors, door/window sensors, and smart plugs and all work consistently. I was very excited when I saw they came out with a presence sensor. Unfortunately at this point I can't even get it to work. I have it integrated right into my Homey Pro and I can see it listed in my devices. I've created routines to control my smart lighting and so far it's come on once or twice at an odd time and that's it. I do like the flashing light on the top and that it's powered by USB-C and that it's a Zigbee repeater but none of the advertised features matter much if I can't get it to work. I'll continue to troubleshoot but as someone who has over 100 smart devices and tries to stay current with it, if it's this difficult, that's usually not a good sign.

I’ve been really impressed with the Third Reality Smart Presence Sensor R3. Right out of the box, it offers true plug-and-play setup—no accounts to create and no need to download the Third Reality app first. Just plug it into USB-C power, and it works immediately as a standalone presence detector. The built-in night light automatically shifts colors to give you a quick visual on your room's air quality, turning on when you enter and off when you leave. it can also pairs directly over Zigbee to platforms like Alexa, SmartThings, or Home Assistant. it also acts as a Zigbee 3.0 router/repeater that extend the range and stability of the Zigbee mesh network by relaying signals between hub and other battery-powered Zigbee devices. The built-in radar is fast and reliable, making it easy to build routines that turn lights or climate control on and off based on whether someone is actually in the room. Just for fun, you can even set up an Alexa routine to give you a customized voice greeting the moment you walk in. It’s a handy, versatile little device that does its job exceptionally well.

I ordered two of them a few months ago. I needed better presence sensor to keep lights on when I am in the room. I have to update the firmware and it took some time. need to be patient. I use Home Assistant and I updated everything to latest. I have to change the settings abit to make it work good. for example, for my front door lights, I had to set it to 2 for motion setting. for bathroom lights, I have to set it to 4. I use automation scripts with those things. it is still working great for me.

So far I've found it to be a good entry point to presence detection. It offers simple controls and limited configurability, but that's not who this device is aimed at. It was easy to set up, and so far has just worked with HomeAssistant. I do wish it was slightly more configurable - namely I wish there was some ability to tap into the accuracy of the sensor to gather information like heart rate sensing. The VoC sensor does not seem to be configurable through HA. They seem to be of varying levels of sensitivity. One got set off today (turned blinking red) because my cat sat under my desk and groomed himself.

Not sure why this is marketed as a presence sensor given it simply detects motion. Technically it may detect presence, but the smartthings driver publically available does not offer presence - just motion. Frustrating this company can't offer drivers to support their products.

I have not paired this yet with Zigbee, but my experience with ThirdReality is that their products work well with Zigbee. This sensor is a VOC sensor and presence sensor and a night light. The VOC sensor doesn't seem to be terribly sensitive, like my Amazon air sensors. I mainly bought these for presence sensor, which does work well. Very speedy and a pretty broad coverage pattern. It can't reliably detect my dog, as others I have tested couldn't detect dogs reliably either.
