Aeotec SmartThings Motion Sensor Review: The Reliable, Fast Zigbee Sensor SmartThings and Hubitat Users Swear By
This rebranded Samsung SmartThings sensor pairs instantly, detects motion in milliseconds, includes a temperature sensor and has great battery life, but it's a trigger-style sensor with no sensitivity adjustment and needs a Zigbee hub.
The Aeotec SmartThings Motion Sensor (a rebrand of the well-regarded Samsung SmartThings sensor) is a Zigbee motion sensor that owners rate highly (a 4.6-star average), and the reviews are unusually consistent: for SmartThings and Hubitat users, it's the best Zigbee motion sensor many have tried. It pairs immediately, is essentially 100% reliable (no false positives or missed detections for most), and triggers in milliseconds, going from motion to light-on almost instantly. It also includes a built-in temperature sensor (reporting in fine increments), which owners use for clever automations (like keeping bathroom lights on during a hot shower), and a magnetic ball mount that makes aiming easy. Battery life is a standout, its CR2 battery lasts far longer than the notoriously battery-hungry older Samsung sensors (owners report 100% after months, even in a 100F+ attic), and it sends a low-battery notification at 5%. It works with SmartThings, Hubitat, Home Assistant (via a Zigbee dongle) and Alexa, and importantly you don't need the official SmartThings hub, any compatible Zigbee hub works. The main limitations: it's a trigger-style sensor with no sensitivity adjustment, so it detects movement quickly but will shut off if there isn't continuous, detectable motion (it's not for holding something on while you sit still, pair it with a microwave/mmWave sensor for that). It requires a Zigbee hub, isn't rated for outdoor use, and some wish it were cheaper. For fast, dependable, hub-based Zigbee motion detection, it's a top pick, so much so that owners buy them by the dozen.
- SmartThings and Hubitat users
- Home Assistant setups (via a Zigbee dongle)
- Fast, reliable motion triggers for lighting
- Automations that also use temperature
Pros
- Extremely reliable and fast (millisecond triggering); pairs instantly
- Built-in temperature sensor enables smart automations
- Excellent battery life (far better than older Samsung sensors); low-battery alert
- Works with SmartThings, Hubitat, Home Assistant and Alexa (any compatible Zigbee hub)
Cons
- Trigger-style with no sensitivity adjustment (not for stillness/micro-movement)
- Requires a Zigbee hub
- Not rated for outdoor use
- Some find it a bit pricey
Who is the Aeotec SmartThings Motion Sensor for?
This is a Zigbee motion sensor (a rebrand of the Samsung SmartThings sensor) with a built-in temperature sensor and a magnetic ball mount, covering about 120 degrees to 4.5m/15ft on a CR2 battery. It requires a Zigbee hub, but works with SmartThings, Hubitat, Home Assistant (via a Zigbee dongle) and Alexa, no official SmartThings hub required. It's ideal for hub-based smart-home users who want fast, dependable motion triggering for lighting and automations, plus temperature data. It's not for you if you have no Zigbee hub, need adjustable sensitivity or detection of very small movements, or want an outdoor-rated sensor.
What buyers love
Reliability and speed dominate the praise. Long-time SmartThings and Hubitat users who've tried many Zigbee (and Z-Wave) sensors call this the best by far, pairing immediately, working essentially 100% of the time, and triggering in milliseconds. The magnetic ball base makes aiming easy, the built-in temperature sensor enables smart automations (like keeping the shower lights on when the temperature rises), and it pairs cleanly without interfering with other Zigbee devices, even through Zigbee wall switches and outlets. Battery life is a repeated highlight: the CR2 lasts far longer than older Samsung sensors, holding up at 100% after months and even in a hot attic, with a low-battery notification at 5%. It works across SmartThings, Hubitat, Home Assistant and Alexa (any compatible Zigbee hub), and owners are so happy they buy multiples, often a dozen or more.
What to know before you buy
The key limitation is that it's a trigger-style motion sensor with no sensitivity adjustment. It's excellent for quickly detecting movement and triggering an action, but it will turn off unless there's continuous, easily detectable motion, so it's not the sensor for keeping something on while you sit still or for catching tiny movements. Owners who need that pair it with a microwave/mmWave sensor to hold the state, using the Aeotec as the fast initial trigger. It also requires a Zigbee hub (though any compatible one works, not just SmartThings), and it isn't recommended for outdoor use (some run it in covered areas anyway). A few owners feel it's a bit pricey and wish for a lower cost. Otherwise, complaints are rare, which is unusual for a smart motion sensor.
Is the Aeotec SmartThings Motion Sensor worth it?
For hub-based users, absolutely. It's fast, reliable, easy to pair, includes a handy temperature sensor, and has excellent battery life, an unusually complaint-free sensor that earns its 4.6-star average and inspires owners to buy it in bulk. Just set expectations: it's a trigger sensor with no sensitivity control (not for stillness detection or micro-movements), it needs a Zigbee hub, and it's indoor-only. If you run SmartThings, Hubitat or Home Assistant and want dependable, near-instant motion triggering for lighting and automations, it's one of the best choices available; if you need presence detection or adjustable sensitivity, pair it with an mmWave sensor or pick a different type.
Frequently asked questions
Do I need a SmartThings hub?
You need a Zigbee hub, but not specifically SmartThings. Owners pair it with SmartThings, Hubitat and Home Assistant (via a Zigbee dongle), as well as Alexa, and note that any compatible Zigbee hub works, including cheaper alternatives to the official SmartThings hub.
Will it keep a light on while I sit still?
No, this is its main limitation. It's a fast trigger-style sensor with no sensitivity adjustment, so it detects movement quickly but shuts off without continuous, detectable motion. To hold a light on while stationary, owners pair it with a microwave/mmWave sensor and use the Aeotec as the initial trigger.
Does it have a temperature sensor?
Yes. It includes a built-in temperature sensor that reports in fine increments, which owners use for clever automations, for example, keeping bathroom lights on during a shower by combining motion state with a temperature threshold. It's a genuinely useful bonus over motion-only sensors.
How is the battery life?
Excellent. The CR2 battery lasts far longer than the older, battery-hungry Samsung SmartThings sensors, with owners reporting 100% after months of use, even in a hot attic. It also sends a low-battery notification at around 5%, making it low-maintenance once installed.
Can I use it outdoors?
It isn't rated for outdoor use. Some owners run it in covered, weather-protected areas (like a sheltered porch) and report good results, but for reliable outdoor detection you should choose a weatherproof sensor. Indoors, it's fast and dependable.
