Review: This is the presence sensor I've been waiting for! - 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 :)
Review: Works well, firmware needs work - 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.

## Features

- Simplified 60 GHz mmWave Presence Detection: Utilizing advanced 60 GHz millimeter-wave radar, this technology accurately detects real human presence—even when you remain still—by sensing subtle micro-movements such as breathing. It is ideal for bedrooms, bathrooms, and other quiet indoor spaces where traditional motion sensors fall short. Instead of complicated parameter adjustments, only the detection distance needs to be set to prevent false triggers.
- RGB Light with Visual Status Indication：The built-in RGB light is not only for ambient lighting, but also works as a visual indicator for presence, automations, or system status. Different colors or brightness levels can be used to clearly show room occupancy or smart home states at a glance.
- Presence + Light, Designed to Work Together：By combining always-on presence detection with an RGB indication light, R3 enables more natural automations — lights remain on while you’re present and turn off only when the room is truly vacant, improving comfort and everyday energy efficiency.
- USB-C Powered & Zigbee Repeater：Powered via USB-C (5V/1A), R3 delivers stable, continuous operation without batteries. Using Zigbee 3.0, it integrates smoothly with platforms like Home Assistant (ZHA & Z2M) and also functions as a Zigbee repeater to help strengthen your mesh network.
- Ambient Light & Air Quality Awareness: Built-in ambient light (Lux) sensing and air quality (TVOC) monitoring provide additional environmental awareness to support advanced automations and insights when supported by your platform. Note: Availability of Lux and TVOC data depends on platform support. The indicator light will flash red when dangerous air quality is detected based on TVOC levels.
- Fast, Stable Zigbee 3.0 Connection: Powered by low-energy Zigbee 3.0, it offers instant integration with Home Assistant via ZHA or Z2M, SmartThings (2015/2018), Aeotec and Echo devices with built-in Zigbee hubs, including Echo (4th Gen), Echo Plus (1st & 2nd Gen), Echo Studio, Echo Show 8 (3rd Gen), Echo Show 10 (2nd & 3rd Gen), Echo Hub, Eero 6, Eero Pro 6.

### ⭐ Feels like a early release with bugs
*by R***O on April 4, 2026*

Tried this sensor with Hubitat using a community-built driver since no official driver exists yet. Initial performance was promising — mmWave occupancy detection and presence sensing worked well. Illuminance reporting works but is extremely chatty, firing every 1-2 seconds with minor lux changes which could stress a busy Zigbee network. The air quality (TVOC) sensor is the main concern. It reported real values briefly after initial pairing then degraded to zeros and never recovered. Extensive debugging using raw Zigbee frame analysis confirmed the device is transmitting zero on every report — this is not a driver issue. Other Hubitat users have reported identical behavior. The device is listed as "coming soon" on THIRDREALITY's own website suggesting the firmware may not be production ready. THIRDREALITY support was responsive and offered a replacement unit. Given that multiple users across independent drivers are seeing the same TVOC failure I believe this is a systematic firmware issue affecting the initial production batch rather than an isolated defect. Holding off on a replacement until firmware maturity is confirmed by the community. Hardware design seems promising — the TVOC sensor just isn't working yet.
