Looking for the best Zigbee sensors to supercharge your Home Assistant setup? After testing dozens of sensors over the past two years, I’ve compiled this comprehensive guide to help you find the perfect sensors for temperature monitoring, motion detection, door/window sensing, and more.

Why Zigbee Sensors Are Perfect for Home Assistant

Zigbee sensors offer several advantages over WiFi alternatives: lower power consumption (battery life of 1-2 years), mesh networking that extends range, and no WiFi congestion. Plus, they work entirely locally with Home Assistant—no cloud required.

Best Overall: Aqara Temperature and Humidity Sensor

The Aqara Temperature and Humidity Sensor is my top pick for most Home Assistant users. It’s accurate, affordable, and has excellent battery life (up to 2 years on a CR2032 battery).

Key Features:

  • Temperature range: -20°C to 60°C (±0.3°C accuracy)
  • Humidity range: 0-100% RH
  • Compact design with LCD display
  • Works with any Zigbee coordinator

I have 8 of these throughout my house monitoring every room. The temperature accuracy is spot-on when compared to my calibrated thermometer. Check current price on Amazon.

Best Motion Sensor: Aqara Motion Sensor P1

For motion detection, the Aqara Motion Sensor P1 is unbeatable. Unlike the older model, it supports custom detection intervals down to 1 second, making it perfect for lighting automation.

Why I Love It:

  • Adjustable detection interval (1s to 200s)
  • 120° detection angle
  • Up to 10 meters range
  • 2 year battery life
  • Light sensor included

I use these for all my motion-activated lighting. The quick response time means lights turn on instantly when you enter a room. Get the Aqara Motion Sensor P1 here.

Best Door/Window Sensor: Aqara Door and Window Sensor

The Aqara Door and Window Sensor is tiny, reliable, and lasts forever on a single CR1632 battery (2+ years in my testing).

Perfect For:

  • Security monitoring (detect open doors/windows)
  • Automation triggers (turn on lights when door opens)
  • HVAC optimization (pause heating/cooling when windows open)
  • Notification alerts

The small form factor means they’re barely noticeable on door frames. I have 12 of these on every exterior door and ground-floor window. Order from Amazon.

Budget Pick: SONOFF SNZB-02 Temperature Sensor

If you’re on a tight budget, the SONOFF SNZB-02 offers excellent value. At roughly half the price of Aqara sensors, they’re perfect for monitoring less critical spaces like garages or storage rooms.

Specifications:

  • Temperature: -9.9°C to 60°C
  • Humidity: 0-99% RH
  • Battery life: 1+ year
  • Works with Zigbee2MQTT and ZHA

Best Water Leak Sensor: Aqara Water Leak Sensor

Protect your home from water damage with the Aqara Water Leak Sensor. I have these under every sink, near the water heater, and by the washing machine.

Features:

  • Instant alerts when water detected
  • 80dB alarm (can be disabled)
  • IP67 water resistant housing
  • 2 year battery life

These sensors have literally saved me thousands of dollars—one detected a slow leak under my kitchen sink before it caused damage. Buy the Aqara Water Leak Sensor.

Best Vibration Sensor: Aqara Vibration Sensor

The Aqara Vibration Sensor is incredibly versatile. I use them for detecting washing machine cycles, mailbox notifications, and even door knocks.

Creative Uses:

  • Washing machine/dryer completion notifications
  • Window break detection
  • Mailbox alerts
  • Door knock detection (better than doorbell for interior doors)

Get the Aqara Vibration Sensor.

Premium Option: Aqara FP2 mmWave Presence Sensor

The Aqara FP2 is a game-changer for presence detection. Unlike PIR sensors that only detect motion, this mmWave radar detects stationary presence—perfect for office or bedroom automation.

Advanced Features:

  • Detects presence even when stationary (sitting at desk, sleeping)
  • Multi-zone detection (up to 10 zones in one room)
  • 5-meter range with 120° coverage
  • USB-powered (no batteries needed)
  • Works over Thread/Matter and Zigbee

This sensor is pricier than PIR options, but the ability to detect stationary presence makes it worth every penny for key rooms. Check price on Amazon.

Best Button: Aqara Mini Switch

The Aqara Mini Switch is perfect for controlling scenes and automations. I use them as bedside switches for “goodnight” routines and by the door for “leaving home” automations.

Actions Supported:

  • Single press
  • Double press
  • Long press

Order the Aqara Mini Switch.
