Listed in the Z2M Database

Zigbee2MQTT’s supported-devices list is the source of truth. Search the exact model number (SNZB-02D, RTCGQ14LM and so on) and check which features are exposed before buying a new or unfamiliar device.

Routers Build the Mesh

Mains-powered devices (plugs, bulbs, relays) act as Zigbee routers and relay traffic for battery sensors. Buy a few routers first, spread them through the house, then add sensors.

Battery Type & Life

CR2477 and AAA cells last much longer than tiny CR2032s. Multi-year battery claims assume default reporting; aggressive reporting intervals in Zigbee2MQTT will shorten them.

Brand Quirks

Aqara battery devices sometimes leave routers from other brands, so they behave best near Aqara-friendly routers or the coordinator. Generic Tuya clones can vary between batches, which is why we favor brands with consistent firmware.

Zigbee, Not Thread

Many brands now sell Matter-over-Thread versions of the same sensors. Look for “Zigbee 3.0” and “hub required” in the listing, and avoid models that say Thread or Matter only.

SONOFF’s second-generation SNZB-04PR2 contact sensor moves to an AAA battery, which is cheaper to replace and longer-lasting than the coin cells in most contact sensors. It reports open and closed instantly and adds a built-in tamper button that triggers an alert if someone pries it off the frame, which is useful for security automations. It has nearly 300 ratings at around 4.2 stars. The earlier SNZB-04P is a mainstay in Zigbee2MQTT; as this R2 is newer, check that your Z2M version lists it.

The Aqara Motion Sensor P1 is a Zigbee2MQTT favorite because its settings, hidden in Aqara’s app, are fully exposed there: detection timeout, sensitivity and LED behavior, plus a light level reading that lets lights turn on only when the room is dark. Aqara claims up to five years of battery life. Be aware that Aqara’s listing says it requires an Aqara hub and is not compatible with other Zigbee hubs; that is an official support statement, and the P1 is a well-known community-supported device in Zigbee2MQTT. Keep it within reach of a reliable router or the coordinator, since Aqara sensors can be picky about which routers they stay connected to.

PIR motion sensors turn the lights off when you sit still; radar presence sensors don’t. SONOFF’s SNZB-06P uses 5.8 GHz microwave radar to detect people even when they are reading or working at a desk, and a built-in light detector keeps lights off during the day. Because it runs on USB power, it also acts as a Zigbee router. In Zigbee2MQTT you can adjust occupancy sensitivity and timeout. It is cheaper than most mmWave sensors, but radar can see through thin walls and pick up fans or curtains, so mounting and sensitivity tuning matter.

The FP1E is Aqara’s refined mmWave presence sensor, built to detect people who are barely moving with fewer false alarms than cheaper radar units. It runs on Zigbee 3.0 and USB power. Like the P1, Aqara says an Aqara Zigbee hub is required, and Matter support comes through those hubs; the FP1E has community support in Zigbee2MQTT, where you can tune detection range and sensitivity. The US listing had only a handful of ratings when we checked, so it is a premium pick for people who want the most accurate occupancy sensing and are comfortable with Aqara’s quirks.

You don’t need a Hue Bridge to use Hue bulbs: Philips Hue lights are standard Zigbee devices and pair straight to Zigbee2MQTT, where they offer smooth dimming, color temperature control and power-on behavior settings. This White Ambiance A19 2-pack is the newer generation listing, and Philips quotes a very wide tunable-white range on it. Each bulb is mains powered, so it doubles as a router. The drawbacks: Hue is pricier than generic Zigbee bulbs, and bulbs only route when the wall switch stays on, so pair them with smart switches or remotes.

The Hue Smart Dimmer Switch is the easiest way to give guests and family a physical control. It mounts on the wall with no wiring, lifts off its magnetic plate to become a remote, and its four buttons report presses, holds and releases in Zigbee2MQTT, so you can map them to any light, scene or automation in Home Assistant, not just Hue bulbs. With more than 4,000 ratings averaging around 4.7 stars, it is one of the most proven Zigbee remotes on Amazon.

The ZBMINIR2 is a tiny Zigbee relay that hides behind an existing light switch or ceiling fixture, turning a “dumb” circuit into a smart one while keeping your normal wall switch. It needs a neutral wire, and in return it is always powered, so it works as a strong Zigbee router in walls where plugs can’t go. In Zigbee2MQTT you can configure the external switch type and power-on behavior. It has nearly 1,500 ratings at around 4.6 stars. Installation involves mains wiring, so hire an electrician if you aren’t comfortable with it.

A cheap wireless button is surprisingly useful: a “goodnight” button by the bed, a doorbell, a “start the coffee” trigger. The SNZB-01P reports single, double and long presses, giving you three actions per button in Zigbee2MQTT, and its small size means it sticks anywhere. It is a long-supported device and inexpensive enough to scatter around the house.

Leak sensors are cheap insurance under sinks, water heaters and washing machines. THIRDREALITY’s WL2 detects both standing water and dripping, which catches slow leaks earlier, and its housing is rated IP65 so it survives a flood rather than dying in one. THIRDREALITY claims up to three years of battery life. It is a newer model with a small review count, while THIRDREALITY’s earlier leak sensors are well established in Zigbee2MQTT, so confirm WL2 support in your Z2M version.

Stick THIRDREALITY’s vibration sensor on a washer or dryer and Home Assistant can tell you when the cycle ends; put it on a window, mailbox or safe and it becomes a knock or tamper alarm. It detects vibration and adds a built-in 110 dB siren for local alerts, and it has more than 600 Amazon ratings. Sensitivity tuning matters: too sensitive and it fires on footsteps, too low and it misses a quiet dryer.

If you need motion sensors in hallways, closets and garages, the SNZB-03P is the budget workhorse. It uses a large CR2477 cell that SONOFF says lasts over three years, reacts quickly to motion, and is a standard Zigbee 3.0 device without Aqara’s router quirks. In Zigbee2MQTT you can set the occupancy timeout. It lacks the P1’s light sensor and fine tuning, but at its price you can cover every room.

Not every climate sensor needs a screen. The SNZB-02P is a small, screenless sensor for attics, crawl spaces, closets, fridges and server cabinets where nobody looks at it. SONOFF rates its CR2477 battery for up to four years based on internal testing. It has more than 1,600 Amazon ratings and is a common sight in Zigbee2MQTT setups, making it the cheap way to log temperature and humidity in every corner of the house.

Simple triggers?

Scatter a few SNZB-01P buttons for goodnight, doorbell or scene shortcuts.

How do I check if a device works with Zigbee2MQTT?

Search the exact model number on the supported devices page at zigbee2mqtt.io. Each entry shows which features (exposes) are available, any pairing tips, and whether the device has known quirks. If a model isn’t listed, it may still pair, but expect to wait for support or write an external converter.

Do Aqara sensors really work without an Aqara hub?

Officially, Aqara says its Zigbee sensors need an Aqara hub. In practice, popular models such as the Motion Sensor P1 and FP1E are community-supported in Zigbee2MQTT. Their main quirk is that some Aqara battery devices drop off when they connect through certain third-party routers, so keep them near the coordinator or proven routers, and pair them close to where they’ll live.

Which coordinator should I use with Zigbee2MQTT?

Most modern Silicon Labs and Texas Instruments coordinators work. Popular choices include SONOFF’s MG24 and ZBDongle-P sticks and SMLIGHT’s PoE coordinators. See our guide to the best Zigbee dongles for Home Assistant for a full comparison.

Can I pair Philips Hue bulbs to Zigbee2MQTT without the Hue Bridge?

Yes. New Hue bulbs usually pair as soon as you enable joining in Zigbee2MQTT and power them on. Bulbs previously paired to a Hue Bridge may need a factory reset first, which you can do with a Hue dimmer or the Touchlink function in Zigbee2MQTT. Once paired, you lose Hue-app-only features like Entertainment sync but gain full local control.

How many Zigbee devices can Zigbee2MQTT handle?

Zigbee2MQTT itself scales to hundreds of devices; the practical limit is your coordinator and mesh. Each coordinator can only connect a limited number of devices directly, so routers are essential: add mains-powered plugs, bulbs or relays throughout the house and battery sensors will connect through them. A healthy network of 100 or more devices is common.
