Integrating motion sensors with temperature monitoring into your Home Assistant setup can significantly enhance your smart home’s automation, security, and comfort. This list covers some of the best motion sensors that also track temperature, ideal for smart home enthusiasts looking to streamline environmental and presence detection in one device.
Aqara Motion Sensor P1
The Aqara Motion Sensor P1 combines precise motion detection with built-in temperature and ambient light sensors. It uses Zigbee 3.0 for reliable connectivity with Home Assistant via a compatible hub like the Aqara Hub or Zigbee2MQTT. Its battery life extends up to 2 years, making it low maintenance, and it supports advanced features like human presence detection and sensitivity adjustments, ideal for nuanced automation.
Philips Hue Motion Sensor
Philips Hue’s Motion Sensor integrates motion and temperature sensing within the popular Hue ecosystem, which can be bridged into Home Assistant. It communicates over Zigbee and offers a wide detection range of up to 16 feet, with temperature readings that help adjust lighting scenes based on ambient conditions. Its quick response time and easy wall or table mounting make it a versatile choice for smart homes.
The SmartThings Motion Sensor supports motion and temperature monitoring, connecting via Zigbee to Home Assistant through the SmartThings hub or community integrations. It features a compact design and can report temperature changes with ±2°C accuracy. Its customizable motion sensitivity and battery life of up to two years make it a dependable sensor for home automation tasks.
The Sonoff SNZB-03 offers motion detection paired with temperature and light level monitoring via Zigbee. It’s compatible with Home Assistant when used with a Zigbee coordinator like the ConBee II or Zigbee2MQTT. This sensor is budget-friendly yet reliable, with a detection range of about 7 meters and reports temperature in real time for climate-aware automations.
Shelly Motion Sensor 2 is a Wi-Fi-based device that includes motion and temperature sensors. Unlike many Zigbee sensors, it connects directly to Home Assistant over Wi-Fi, eliminating the need for a hub. It supports adjustable motion sensitivity and reports temperature with high accuracy, making it suitable for setups where hubless operation or direct MQTT integration is preferred.
The Ecolink Z-Wave Plus Motion Detector combines motion detection with a temperature sensor and communicates using the Z-Wave protocol. It integrates with Home Assistant through Z-Wave sticks like Aeotec Gen5, offering solid compatibility and long battery life. Its temperature sensor can trigger HVAC automations, making it a good fit for Z-Wave ecosystems.
Fibaro’s Motion Sensor uses Z-Wave Plus and includes motion, temperature, and light sensors in one compact unit. It supports advanced motion detection algorithms and sends temperature updates frequently to enable responsive automations in Home Assistant. Its built-in accelerometer and tamper alarm add extra security features beyond basic detection.
Xiaomi’s Mi Motion Sensor is a popular Zigbee device with integrated temperature sensing, often paired with the Xiaomi Gateway or used with Zigbee2MQTT for Home Assistant integration. It offers solid motion detection with a range of roughly 7 meters and reports temperature changes accurately. Its affordability and wide community support make it an accessible choice for many smart home users.
The Neo Coolcam PIR Sensor is a Z-Wave Plus device that combines motion detection and temperature sensing. It supports multi-channel reporting to Home Assistant, enabling detailed environmental monitoring. Its 5-meter detection range and battery life of up to 2 years make it practical for indoor use where Z-Wave is the preferred protocol.
The Deconz Motion Sensor is a Zigbee sensor designed to work seamlessly with the Deconz gateway and Home Assistant. It monitors motion and temperature with good precision and sends frequent temperature updates for climate automation. Its compatibility with Zigbee2MQTT and the Deconz ecosystem offers flexibility to users prioritizing open-source solutions.
How to Choose
When selecting a motion sensor with temperature monitoring for Home Assistant, consider the communication protocol first: Zigbee, Z-Wave, or Wi-Fi, depending on your existing smart home network. Zigbee and Z-Wave devices typically require a hub but consume less power, offering longer battery life. Wi-Fi sensors often connect directly but may drain batteries faster.
Next, evaluate sensor accuracy and detection range. For motion, look for devices with adjustable sensitivity and a range that suits your room size. Temperature sensor precision and update frequency matter if you plan to use the data for HVAC or climate control automations.
Battery life and maintenance are also key. Devices with multi-year battery life reduce hassle, and those with replaceable batteries can be more cost-effective long term. Finally, check compatibility with Home Assistant integrations like Zigbee2MQTT, Z-Wave JS, or native API support to ensure seamless operation.
Frequently Asked Questions
Can I use these sensors without a hub?
Some Wi-Fi sensors like the Shelly Motion Sensor 2 connect directly to Home Assistant without a hub, but most Zigbee and Z-Wave sensors require their respective hubs or USB coordinators.
How accurate are the temperature sensors?
Most integrated temperature sensors in motion detectors offer ±1 to ±2°C accuracy, sufficient for typical home automation but not for precision climate control.
Do these sensors detect presence or just motion?
Most detect motion (changes in infrared radiation) rather than continuous presence, though some advanced models like the Aqara P1 offer human presence detection features.
Can I automate HVAC based on these sensors?
Yes, temperature readings from these sensors can trigger heating, cooling, or ventilation automations in Home Assistant for improved comfort and energy efficiency.
Are these sensors compatible with voice assistants?
Many, especially those in ecosystems like Philips Hue or SmartThings, can be integrated with Alexa or Google Assistant, but direct voice control depends on your setup and bridge compatibility.
Final Thoughts
Choosing a motion sensor with temperature monitoring for Home Assistant depends heavily on your existing smart home ecosystem, desired protocol, and specific automation goals. Devices like the Aqara Motion Sensor P1 and Philips Hue Motion Sensor offer reliable multi-sensor functionality with strong community support. For those preferring hubless setups, Wi-Fi options like Shelly provide flexibility. Ultimately, the right sensor enhances your home’s intelligence by combining presence and environmental awareness in one compact device.
