Aqara built its reputation on small, inexpensive, long-lived sensors. Door contacts, temperature pucks, buttons and motion detectors that run for years on a coin cell and report into whatever platform you already use. For anyone assembling a sensor-heavy smart home, that catalogue is hard to ignore.
The catch is protocol fragmentation. Aqara now ships Zigbee devices, Matter-over-Thread devices, and a few that speak both, and the packaging for two different radios can look nearly identical on a shelf. Buy the wrong one and you either need an Aqara hub you did not plan on, or a Thread border router you do not have.
This guide covers five Aqara products that represent the current range, explains who each one suits, and flags the protocol questions to settle before ordering. It assumes you are running Home Assistant, Apple Home, or both, and that you care about local control.
The lineup at a glance
Aqara’s range splits roughly three ways: the hub that ties everything together, battery sensors, and mains or battery access hardware like locks. The radio each device uses determines what else you need.
| Model | Radio | Power | Needs a hub or border router? | Main job |
|---|---|---|---|---|
| Hub M3 | Zigbee, Thread, Wi-Fi (2.4/5 GHz), Bluetooth, Ethernet with PoE | PoE or USB-C | It is the hub | Matter controller, Thread border router, Zigbee coordinator, IR blaster |
| Door and Window Sensor P2 | Matter over Thread | Battery | Yes — a combined Matter controller and Thread border router | Open/closed contact sensing |
| Presence Sensor FP300 | Thread or Zigbee | 2x CR2450 | Zigbee coordinator or Thread border router, depending on mode | mmWave and PIR presence, light, temperature, humidity |
| Temperature and Humidity Sensor T1 | Zigbee | Battery | Yes — Zigbee coordinator | Temperature, humidity, air pressure |
| Smart Lock U100 | Matter over Thread; Aqara Zigbee 3.0 hub for extra features | 4x AA, USB-C emergency port | Depends on which features you want | Deadbolt with fingerprint, keypad and Apple Home Key |
Hub M3: the piece that makes the rest simpler
The M3 is the most interesting hardware Aqara makes, because it collapses three roles into one box. It acts as a Matter controller, a Thread border router and a Zigbee coordinator, and it bridges Aqara Zigbee devices into Matter ecosystems so Apple Home or SmartThings can see them. Aqara positions it as an edge hub that takes over automations from older Aqara hubs and runs them locally, though some cloud notifications still need internet.
Connectivity is unusually generous for this class. There is dual-band Wi-Fi with WPA3, a PoE Ethernet port, and a USB-C port that accepts a power bank or mini-UPS, plus 8 GB of encrypted local storage for device lists and automation data. A 360-degree IR blaster handles legacy air conditioners and TVs, and it can read status when someone uses the original remote.
Who should skip it: anyone already running a Zigbee coordinator and a Thread border router in Home Assistant. If your Zigbee network lives on a USB stick and your Apple TV handles Thread, the M3 mostly duplicates what you have. Our smart home hub comparison puts the M3 against Home Assistant Yellow, Hubitat and SmartThings if you are still choosing a platform.

Sensors: the protocol matters more than the shape
Two Aqara sensors can look like siblings and behave completely differently on your network. Check the radio on the product page before you add to cart, every time.
Door and Window Sensor P2 (Thread)
The P2 speaks Matter over Thread natively, using a Hall sensor for open/closed detection, and appears directly in Aqara Home, Apple Home, Google Home, Alexa and SmartThings without a vendor bridge. Aqara is explicit that a combined Matter controller and Thread border router is required; the Hub M3 and recent Apple TV 4K models are among the hubs it lists as tested. Automations run locally once paired.
Thread gives you a mesh that routes through mains-powered Thread devices and a single pairing path across ecosystems. The trade-off is that Thread sensors generally draw more power than their Zigbee equivalents, and a Thread network with few routers can be less forgiving than a well-built Zigbee mesh.

Temperature and Humidity Sensor T1 (Zigbee)
The T1 reports temperature, humidity and air pressure, with rated accuracy of ±0.3 °C between -15 °C and 50 °C and ±3% relative humidity. Aqara’s listing calls for an Aqara hub and placement within 400 inches of it. In practice, Aqara Zigbee sensors are among the most widely used devices on Zigbee2MQTT and ZHA, so a Sonoff or SkyConnect dongle is a legitimate route — just accept that Aqara does not support that path.
Zigbee battery sensors like this remain the better pick for scattering ten or twenty measurement points around a house, including monitoring a server closet before it overheats.

FP300: presence detection without running wires
Most capable mmWave sensors need USB power, which limits where they go. The FP300 runs on two replaceable CR2450 cells and combines 60 GHz mmWave radar with PIR, plus light, temperature and humidity sensing. Aqara quotes up to three years of battery life in Zigbee mode and up to two years in Thread mode — a useful illustration of the radio trade-off in a single product.
Coverage is a 120-degree field of view out to roughly 6 m, on a multi-axis mount for wall, ceiling or corner placement. That suits bathrooms, hallways and home offices where a PIR sensor keeps dropping lights on someone sitting still. Rooms needing zone targeting or longer reach are better served by a wired sensor; our presence detection sensor guide covers those options.

U100: the lock, and its two different personalities
The U100 deadbolt supports Matter over Thread and Apple Home Key, so an iPhone or Apple Watch unlocks it with a tap even when the phone’s battery is dead. It also takes up to 50 fingerprints, local one-time visitor codes, and a touchscreen keypad. A gyroscope drives auto-lock after the door closes, there is a Do Not Disturb mode, and the zinc alloy body carries an IP65 rating. Four AA batteries are included, rated up to eight months, with a USB-C port for emergency power.
The wrinkle: remotely configurable passwords and third-party integrations such as Google Home, Alexa and IFTTT are tied to an Aqara Zigbee 3.0 hub. Budget for a hub if remote code management matters, and confirm current deadbolt and door thickness compatibility on Aqara’s site, since lock fitment details change between revisions.

The ecosystem, honestly
Aqara Home is competent but it is not where enthusiasts spend their time. Automation logic is simpler than Home Assistant’s, and some features still route through Aqara’s cloud. Device availability also varies by region, so a model listed in one market may not be certified in another.
Skipping the Aqara hub entirely
Pairing Aqara Zigbee devices straight to Zigbee2MQTT or ZHA removes the vendor app and gives you full local entities. It is a popular approach, with two caveats worth knowing: some Aqara devices use non-standard Zigbee behaviour and can be fussy with third-party routers, and firmware updates normally require Aqara’s own hub. If you go this route, read our notes on Zigbee devices dropping off Home Assistant first.
Who should look elsewhere
If you want Z-Wave, mains-powered mmWave with zone control, or a lock certified to a specific regional standard, other brands focus on those areas more directly. Aqara prioritises breadth and battery life over deep configurability.
Common questions
Does the Hub M3 work as a Thread border router for Home Assistant?
It is a Matter controller and Thread border router, and Aqara lists Home Assistant compatibility. Many Home Assistant users instead run their own border router so credentials stay under their control.
Zigbee or Thread for Aqara sensors?
Zigbee if you already run a coordinator and want maximum battery life. Thread if you want direct Matter pairing to Apple Home without a bridge. The FP300’s own battery figures show the gap.
Does the P2 work without any hub?
No. It needs a combined Matter controller and Thread border router, and Aqara maintains a list of tested models.
Why do similar Aqara sensors need different infrastructure?
Because Aqara sells Zigbee and Thread versions with near-identical housings. Read the radio line on the listing, not the product photo.
Which one for your situation
Running Home Assistant with a Zigbee dongle already: buy Zigbee sensors like the T1 and the FP300 in Zigbee mode, and skip the hub. Our Zigbee and Z-Wave dongle guide covers coordinator choices.
Apple Home as the primary platform: the Hub M3 plus the P2 is the cleaner combination, giving you a Thread border router, Zigbee support and IR control in one PoE-powered box.
Starting fresh with Matter in mind: the M3 first, then add Thread sensors as you go, cross-checking the current Matter and Thread hub landscape before committing.
Replacing a deadbolt: the U100 makes most sense for Apple households that want Home Key, with an Aqara Zigbee hub added if remote code management matters. Any wiring or in-wall work around a hub or door strike should follow local electrical code, with a licensed electrician where it is required.
