For years, human presence detection for dwelling automation has been actually exhausting to do nicely, and nearly not possible to do completely. Nonetheless, human presence sensors powered by mmWave radar are threatening to vary that.
Previously, movement detection was executed nearly solely with the usual PIR movement detectors. They work nice IF you’re transferring. However in the event you cease transferring – go to sleep, learn a ebook, watch tv – they now not detect your presence.
Alternatively, mmWave sensors can sense way more refined actions, comparable to respiratory. As well as, the latest fashions can detect distance, which path you’re transferring, and even variety of individuals current.
Issues To Know Earlier than You Purchase
Here’s a checklist of essential components to think about to be sure you get a presence sensor that matches your wants. This consists of particular options of merchandise, and in addition basic “issues to know” about mmwave presence sensors.
Response Time
Lighting is the most typical objective for utilizing these sensors. For that cause, it’s crucial that the sensor responds in a short time to your presence. You need the lights to come back on as quick (or quicker) as you possibly can attain the bodily change and flip on the sunshine. The FP2 and EP1 are the “gold commonplace” for pace responding practically immediately.
Get rid of false positives
There are usually two varieties of errors with presence detection:
- False constructive – The sensor detects presence when it shouldn’t. This can be a quite common drawback with mmWave sensors as a result of they’re so delicate. Even the slightest little bit of movement can set them off. For instance, frequent sources of false positives with mmWave sensors embrace curtains, ceiling followers, and transferring objects seen by means of home windows.
- False unfavorable – The sensor fails to detect presence when it ought to. That is frequent with PIR movement sensors, however solely not often an issue with mmWave.
The way in which to attenuate false positives is to:
- regulate the mounting location and orientation
- configure vary and sensitivity choices (accessible on all sensors aside from the Tuya PS-HPS)
- Use presence “zones” to disregard drawback areas (accessible on Aqara FP1 and Apara FP2)
- Use interference detector to disregard drawback areas (accessible on Aqara FP2)
Zones
Each the FP1 and FP2 break up the world that’s “seen” to the sensor right into a grid of squares. Every sq. can detect presence impartial of the opposite squares. Utilizing the app, you may select a bit of the grid to create a “zone”. Then, automations could be designed for every particular zone.
Activation States
As soon as the seen space is damaged down right into a grid of squares, it’s additionally attainable to trace an object transferring by means of the sensor’s subject of view. It could possibly detect which path an object is transferring, how briskly it’s transferring, and what number of objects there are.
The FP1 can detect path, and the FP2 can detect how briskly (fall detection) and what number of (multi-person detection).
Energy Supply
Presence sensors powered by mmWave radar are continuously sending out pulses and processing the sign that will get bounced again to them. Due to this, they require means an excessive amount of energy to be battery powered. Subsequently, they require a hard-wired connection. Sometimes this takes the type of energy through USB. Nonetheless, a pair fashions may also be wired on to AC energy.
Mounting Location
The sensors could be mounted on a wall or on the ceiling. The situation and orientation of the sensor may have a big impression on the effectiveness of your sensor. For many use circumstances, one of the best orientation can be on a wall. Nonetheless, for fashions which have fall detection, you will have to mount the sensor on the ceiling to make use of that function.
Configuration Choices
In an effort to fine-tune your sensor’s operation on your area, it’s fascinating to have the choice to regulate the sensitivity and vary of the sensor. Mixed with adjusting the mounting location, this may be very useful to eradicate sources of error (false positives and false negatives). All the sensors on this checklist aside from the Tuya PS-HPS have these choices. This type of fine-tuning is much less crucial with a extra highly effective sensor just like the FP2.
Sensible House Integration
All the listed choices are both ZigBee or WiFi. Utilizing ZigBee with a domestically managed hub is the quickest and most dependable technique for integrating your sensor. It eliminates any reliance on cloud purposes. Nonetheless, establishing a hub like that isn’t for the informal consumer. For the informal consumer, a WiFi sensor (just like the FP2) with an app that handles all of your integrations makes extra sense.
Greatest mmWave Presence Sensors
Greatest General – Aqara FP2
After I first noticed what the Aqara FP2 can do, I used to be fully blown away. It successfully addresses a number of issues that earlier mmWave presence sensors have suffered from, and provides new options that can take your house automation capabilities to the subsequent stage.
The FP2 is able to detecting presence practically immediately. Velocity was a significant annoyance with earlier mmWave fashions (aside from the EP1). That drawback seems to have gone away with the FP2.
It could possibly scan for sources of movement that trigger false positives (e.g. ceiling fan) after which ignore these sources sooner or later.
It has a 20 x 16 grid of detection zones. Throughout the app, you should utilize the zones to outline partitions, entrances, and exits. Moreover, you should utilize the zones to interrupt up your giant rooms into smaller areas, every with their very own automation guidelines.
The FP2 helps Apple HomeKit, alongside compatibility with Alexa and Google. It makes use of WiFi and requires the Aqara app for setup.
What I Like
- While you stroll into the room, the lights come on FAST. It’s so quick that it could even be quicker than manually flipping the change. You possibly can even arrange the room boundaries to make the lights come on barely **earlier than** (thoughts blown!) you enter the room.
Earlier than the FP2, one of many main drawbacks of all the favored mmWave sensor choices was a noticeable delay for the preliminary detection of presence. Because the main use case for these sensors is lighting management, you actually need the system to be super-responsive. It must be as quick or quicker than your capability to effortlessly flip a change as you stroll right into a room. The truth is, one of many main causes the EP1 (under) is so standard is that it incorporates a PIR for pace. The FP2 largely eliminates this annoyance and manages to carry out nicely with solely it’s mmWave sensor. - The FP2 can break up the view of the sensor space into zones. This lets you use a single sensor in a big area. Moreover, you may create personalized automations when occupancy is detected in particular zones of that area. That is actually cool and makes some excessive, pointless automations attainable.
- Previously, false positives from ceiling followers, curtains, and even movement exterior the house has been a thorn within the facet of those mmWave sensors. Utilizing the FP2’s “detect interference” function, you may practice the sensor to disregard the movement that’s inflicting the false positives.
What I Don’t Like
- The FP2 makes use of WiFi and requires you to make use of the Aqara app to entry all of the superior mapping capabilities. Subsequently, you might be married to the Aqara app and the related cloud if you wish to use it. Nonetheless, a current replace has made it attainable to work offline utilizing the HomeKit integration.
- Pets will nonetheless set off the presence sensor. This drawback exists with all of the sensors on this checklist, however I particularly listed it right here as a result of it’s the solely “human presence sensing” associated subject that the FP2 has. It appears to have solved the opposite frequent issues. I don’t see a simple means round this.
Verdict
Aqara is mild years forward on this. At this level, there may be nothing else prefer it (that I do know of).
The EP1 performs as nicely within the pace class, however doesn’t have the zoning capability or the interference detection. The FP1 does have the zoning capability (at a lesser decision), however lacks the pace and the interference detection of the FP2.
There are in all probability some hardcore automation individuals that can flip their nostril up on the WiFi and cloud requirement. However for the overwhelming majority of individuals, this presence sensor opens up a world of presence-based automation that was beforehand both extraordinarily tough, ineffective, or each.

This all-in-one presence sensor was designed for dwelling automation geeks by a house automation geek. It’s packed stuffed with sensors. It consists of the next:
- mmWave sensor
- PIR sensor
- Temperature and humidity sensor
- Mild sensor
- Bluetooth and WiFi module
Nonetheless, the EP1 is not for the informal sensible dwelling consumer. There isn’t a devoted app to carry your hand by means of the setup course of. In an effort to use the EP1 you’ll need to have a House Assistant setup, and be aware of ESPHome.
What I Like
- You possibly can create superior presence-based automations utilizing solely the sensors contained inside this machine. For instance, activate/off lights or HVAC primarily based on individuals within the room, use the sunshine sensor to find out whether or not lights must be turned on and at what depth, or combine the Bluetooth tracker to establish who’s within the room so as to create customized automations.
- This machine is totally native. At no time do you need to hook up with an exterior cloud app or account.
- It’s customizable. Each the mmWave sensor and the PIR sensor are detachable and due to this fact upgradeable. Additionally, it comes with ESPHome put in, however you may flash it with your individual alternative of firmware if that’s your factor. Lastly, the board has 4 extra GPIO pins for personalization.
- Because the mmWave sensor makes use of a lot energy that it requires a hard-wired supply, it makes a variety of sense to pack a bunch of different sensors into it. This manner, they will all be hidden in the identical place they usually can all share the identical energy supply. Usually, you may need these 2 or 3 different sensors unfold throughout the room and every would have their very own battery that periodically wants changing.
- By shopping for the EP1, you might be supporting a small enterprise and a creator that has executed some actually superior issues within the dwelling automation neighborhood. This product began as a DIY mission on Youtube. The mission acquired a lot constructive suggestions that the creator determined to show it right into a manufacturing mannequin. The EverythingSmartHome Youtube channel is stuffed with detailed descriptions of tips on how to accomplish distinctive and helpful duties in House Assistant.
What I Don’t Like
- The EP1 makes use of a 24GHz mmWave sensor. This usually means it will likely be much less in a position to detect very small actions in comparison with a 60GHz mmWave sensor.
Moreover, it will increase the efficient distance of the sign, and the power of the sign to penetrate objects. That in all probability feels like a very good factor. Nonetheless, an excessive amount of distance and penetration could cause false positives if the sign begins choosing up movement by means of partitions.
Fortuitously, if these potential points are literally drawback, you possibly can all the time swap out the present mmWave sensor for one in all your selecting. - It doesn’t at the moment assist area detection. The power to outline which areas can set off an automation is extraordinarily helpful for eliminating false positives. For instance, if the sensor retains choosing up curtains blowing from an air vent, you may eradicate that area from the set off area.
Verdict
As you may see, there’s lot’s to love concerning the EP1. Its smorgasbord of sensors make it the swiss military knife of presence detection. It’s capability to automate utilizing solely the onboard sensors is unbeatable. Nonetheless, it’s probably not for the informal consumer that’s used to downloading an app and syncing their machine with Alexa. Moderately, it’s way more for the ability consumer because it requires a good quantity of know-how to get it working and to take advantage of use of all its options.

Inovelli’s strategy of mixing the sensor and the sensible change successfully solves two frequent issues:
- mmWave sensors use a variety of energy and due to this fact require hard-wiring. Because the sensors are usually mounted in the course of a wall someplace, its tough to get energy to the sensor with out operating an unpleasant wire up the wall. If the sensor is built-in right into a change, there may be already a built-in energy supply.
- One other subject frequent to almost all sensible dwelling sensors is determining a spot to place them. With the sensor constructed right into a change field, it has a everlasting place that’s aesthetically accetable. An added bonus is that it may well’t be tampered with, knocked off a shelf, or sucked right into a vacuum.

Greatest Worth – Tuya ZY-M100
The Tuya ZY-M100 is a succesful presence sensor at a low worth.
It has choices for configuring the sensor sensitivity and vary, however lacks choices for sensing occasions just like the Aqara FP1. With correct configuration, the sensor will detect your presence while you enter the room inside 1 second and generally even much less.
It’s accessible as a wall-mounted model, which seems to be like a typical sensor, or as a ceiling-mounted model which seems to be much like a recessed mild. It’s additionally accessible with both ZigBee connectivity or WiFi.
Yow will discover the identical sensor being offered by many alternative manufacturers (and generally unbranded). It’s simply recognizable by the goofy stick human icon printed on high of the sensor.
What I Like
- The ZY-M100 presents comparable efficiency and comparable configuration choices to the FP1 at barely greater than half the worth.
- This sensor is accessible in each a ZigBee model and a WiFi model. The WiFi model requires the usage of the Tuya cloud, which I choose to keep away from. However, in the event you’re snug with it, you should utilize it and considerably simplify the setup and operation.
What I Don’t Like
- It doesn’t assist the usage of areas. This can be a actually highly effective function which is supported by each the Aqara FP1 and FP2
- It doesn’t assist the “strategy” occasion just like the Aqara FP1.
Verdict
If I might’ve been in a position to get my fingers on this machine 2 years in the past, I might’ve been totally impressed. Nonetheless, the mmWave presence sensors have superior so shortly that the Tuya ZY-M100 is now the discount possibility. It presents a fairly quick response time, and sufficient customization choices to fine-tune the sensor in order that it operates successfully inside your area.
It’s about 1/3 the worth of the Aqara FP2 and is available on Aliexpress and infrequently on Amazon. For those who store round on Aliexpress, you may generally discover them actually low-cost. On the time I printed this, the shop linked under had it listed at $15.54.
Different for Native Management – Aqara FP1
Aqara’s FP1 presence sensor has been a significant a part of all the excitement surrounding mmWave presence sensors within the dwelling automation neighborhood. Nonetheless, it’s solely a 12 months outdated and it’s already been changed by the FP2.
Because the predecessor to the FP2, it shares among the identical options, however they’re simply not as good.
The FP1 is the one different mmWave sensor that has detection zones (7 x 4 grid) inbuilt.
Its binary sensor performs about the identical (speed-wise) because the Tuya ZY-M100 and usually takes 0.5 – 1.0 sec (however generally a number of seconds)to detect presence. Nonetheless, you should utilize the “strategy” occasion to make it reply considerably quicker (persistently < 0.5 sec).
The FP1 makes use of ZigBee for connectivity and is absolutely supported by standard ZigBee purposes comparable to ZigBee2MQTT. It’s additionally suitable with HomeKit.
What I Like
- It has configuration choices for movement sensitivity and for strategy distance. These could be tinkered with to hopefully eradicate sources of false positives.
- Its 7 x 4 grid of detection zones can doubtlessly be used to filter out extra sources of false positives.
- The FP1 makes use of ZigBee and is absolutely supported (areas too! – right here’s tips on how to do it) by ZigBee2MQTT. Utilizing this, you may configure and use the machine fully domestically.
What I Don’t Like
- There isn’t something that actually stands out to dislike concerning the FP1. Like I stated above, it’s a succesful sensor, however simply not as highly effective because the FP2. It’s slower and has much less decision.
Verdict
The FP1 was one of the best accessible mmWave presence sensor final 12 months. However, it’s been handed up by each the FP2 and the EP1. It’s nonetheless a succesful sensor, however at its present worth level of about $50, it’s type of in a “no man’s land” worth vary. Let me clarify:
For my part, we’re going to see a really quick evolution of those mmWave sensor merchandise. For that cause, I might keep away from shopping for a “center of the highway” product just like the FP1 right now. As an alternative, I might both:
- Save just a little cash by going with the cheaper ZY-M100 now, with the intent of upgrading to way more highly effective sensor within the comparatively close to future.
- Spend just a little extra proper now to get the FP2 which is far more highly effective and succesful and may be capable of maintain its personal for no less than a couple of years.
Because the FP2 is WiFi, the FP1 is an okay possibility for these of you that insist on utilizing “native solely” gadgets. However even in that case, I might lean in the direction of saving just a little cash by going with the cheaper ZY-M100.
Out of date – Tuya Human Presence Sensor (Tuya PS-HPS)
No merchandise discovered.
This human presence sensor could be discovered on Aliexpress and infrequently on Amazon. It’s incessantly listed and not using a mannequin identify and is usually simply referred to as Human Presence Sensor. Nonetheless, it’s simply recognizable by it’s comically giant black case that makes it seem like a gateway. It makes use of a 24 GHz mmWave module which may precisely sense presence as much as 3m.
What I Like
- It does a very good job of detecting presence. It’s simply takes longer than the opposite choices. For lighting purposes, that is no good (see under). Nonetheless, not all purposes must be as “fast-acting” as lighting. For instance, it may work simply advantageous for room to room temperature management.
What I Don’t Like
- It usually takes wherever from 1-5 seconds to detect presence. That is an unacceptably very long time if you will use it to activate lights while you stroll right into a room. I personally discover it annoying if there’s even a half-second delay.
Subsequently, if you wish to use it for lighting, you’ll nearly actually need to set up a PIR sensor (a lot quicker) to set off the preliminary “mild on” automation. Then, depend on the mmWave sensor to maintain the lights on till you allow. This 2-sensor system can work, nevertheless it provides complexity to the automation code, and the price of one other sensor. - You can not regulate vary or sensitivity. The default settings are what you get.
- It’s large. It’s mainly double the size and double the width of the opposite sensors. No thanks.
Verdict
At this level, the sensor is actually out of date. The value distinction between it and the opposite low-cost possibility (Tuya ZY-M100) is minimal. However, the efficiency and flexibility is considerably weighted in favor of the ZY-M100. I see no cause to purchase this sensor, however I’ll nonetheless go away a hyperlink to 1 so you realize which one to keep away from.
FAQs
Remaining Ideas
After spending means an excessive amount of time researching all these sensors, I discover it tough to advocate something apart from the Aqara FP2. For my part, the next two options alone make it higher than the others:
- it’s capability to filter out false constructive sources
- its lighting quick responsiveness
However that’s not all of the FP2 brings to the desk. When you add within the high-resolution grid for room mapping, there’s actually no comparability.
The one cause you may need to keep away from the FP2 is due to its dependence on the Aqara app. In case you are adamant about native management and actually need to experiment with “areas”, the FP1 is your solely possibility. Nonetheless, I don’t assume the FP1 is an excellent worth. While you evaluate it to the FP2, it’s merely under-powered. Provided that truth, and the way shortly I anticipate these gadgets to evolve, I don’t assume it can take lengthy for the FP1 to be out of date. To me, in the event you insist on shopping for a presence sensor proper now (and don’t need the FP2), I might somewhat “get by” with the ZY-M100 and plan on ditching it for one thing extra just like the FP2 when an area model turns into accessible.
That stated, I’ve not but outfitted my complete home with Aqara FP2’s. To this point I’ve solely purchased one, and I’ve been having enjoyable enjoying with it.
