Best Presence Sensors for Smarter Automation
Best Presence Sensors
for Smarter Automation
Presence sensors solve one of the biggest weaknesses in ordinary smart-home routines: they can keep detecting a person who is sitting still. That makes lighting, climate, security, and room-based automations more accurate and less annoying.
The Aqara FP2 is the strongest mainstream choice for multi-zone rooms and major smart-home platforms. Everything Presence Lite is the best value for Home Assistant users who want local zone tracking. Apollo MSR-2 is ideal for compact, expandable Home Assistant deployments, while Everything Presence One is the best hybrid option for users who want both fast PIR response and sensitive mmWave still-presence detection.
Presence sensors make automations feel less robotic.
Traditional PIR sensors are excellent at detecting someone entering a room, but they may stop seeing a person who sits still. mmWave radar can detect much smaller movement, including breathing and subtle body motion.
Lights stay on appropriately
A reading lamp or office light can remain on while someone is seated, then turn off after the room is truly vacant.
Climate follows occupancy
Heating, cooling, fans, and ventilation can respond to whether a space is actually being used.
Zones create context
Advanced sensors can distinguish a sofa, desk, bed, or kitchen zone and trigger different routines inside one room.
Privacy stays intact
Radar presence sensors can provide room awareness without using a camera or recording identifiable video.
Energy waste drops
Lighting and HVAC no longer need to run based on long motion timeouts or fixed schedules.
Local control is possible
Several enthusiast-focused sensors process automations locally through Home Assistant or ESPHome.
Presence sensor comparison

The best sensor for each use case
These are editorial fit ratings based on features, platform support, architecture, and intended use—not laboratory testing.
Aqara Presence Sensor FP2
Aqara's FP2 is the best fit for homeowners who want advanced room mapping without building a Home Assistant system. Aqara lists coverage up to 40 square meters, up to 30 configurable zones, multi-person detection for up to five people, a built-in light sensor, and direct support for major smart-home platforms.
What we like
- Multi-zone room mapping
- Broad platform compatibility
- No hub required
- Local automations with supported ecosystems
Considerations
- Requires constant USB power
- Room mapping takes setup and tuning
- Reflections and placement can create ghost detections
- Uses 2.4 GHz Wi-Fi rather than Zigbee
Everything Presence Lite
Everything Presence Lite combines a 24 GHz LD2450 radar, local ESPHome processing, multi-target tracking, customizable Home Assistant zones, a light sensor, and Bluetooth proxy capability at an approachable price.
What we like
- Tracks up to three targets
- Up to four dynamic zones
- Local and privacy-focused
- Strong value for advanced users
Considerations
- Designed primarily for Home Assistant
- Zone configuration requires more technical work
- USB power and Wi-Fi are required
- Less plug-and-play than mainstream sensors
Apollo Automation MSR-2
The Apollo MSR-2 is a compact, open-source Home Assistant sensor built around LD2410B mmWave radar. It also includes light, UV, temperature, and pressure sensing, with optional CO2 expansion, an RGB LED, and a buzzer.
What we like
- Compact and expandable
- Local ESPHome integration
- Excellent still-presence sensing
- Useful environmental data
Considerations
- Single-target tracking
- Home Assistant focus limits mainstream appeal
- mmWave can detect through light walls
- Requires careful range and gate tuning
Everything Presence One
Everything Presence One combines mmWave radar with an industrial PIR sensor. The PIR supplies fast initial motion response, while mmWave helps keep the room occupied when someone sits still. It also includes temperature, humidity, ambient light, Bluetooth proxy capability, and expansion pins.
What we like
- Fast PIR plus sensitive mmWave
- Strong environmental sensor package
- Local ESPHome architecture
- Highly adjustable and expandable
Considerations
- More expensive than the Lite
- Primarily aimed at enthusiasts
- Requires tuning for the room
- Long radar range can detect beyond the intended area
The sensor is only as smart as its installation.
mmWave is extremely sensitive. That is its advantage and its biggest setup challenge.
Avoid moving objects
Fans, curtains, plants, robot vacuums, and pets can create unwanted presence events.
Watch for reflections
Glass, mirrors, metal appliances, and large reflective surfaces can create ghost targets or distorted zones.
Limit the detection range
Reduce range so the sensor does not detect people through walls or in an adjacent hallway.
Use PIR for fast entry
Hybrid sensors can react quickly when someone walks in, then rely on mmWave to maintain occupancy.
Plan for constant power
Most advanced presence sensors require USB power and do not operate as simple battery devices.
Tune before automating
Verify detection, absence timing, and zones before connecting lights, HVAC, locks, or security actions.
Start with lighting in one non-critical room. Once presence and absence are reliable, expand into HVAC, security, shades, and other automations.
Choose the platform before the product.
For Apple, Alexa, or Google
Aqara FP2 provides the broadest mainstream ecosystem compatibility in this comparison.
For Home Assistant value
Everything Presence Lite delivers local zone tracking and multi-target data at a lower price.
For compact rooms
Apollo MSR-2 offers strong still-presence detection and additional environmental sensing.
For fast entry response
Everything Presence One combines PIR and mmWave, which can make lighting feel more immediate.
For large open rooms
Choose a sensor with configurable zones, target tracking, and enough range for the full space.
For simple closets and halls
A traditional PIR motion sensor may still be cheaper, faster, and completely adequate.
Presence sensor questions
What is the difference between a motion sensor and a presence sensor?
A traditional PIR sensor is best at detecting larger movement, such as someone entering a room. A presence sensor—usually using mmWave radar—can detect much smaller movement and may continue recognizing someone who is seated or sleeping.
Can mmWave presence sensors detect through walls?
Some can detect through drywall, doors, glass, or furniture depending on power, frequency, distance, and sensitivity. This is why range and detection gates should be tuned carefully.
Do presence sensors require a hub?
It depends. Aqara FP2 connects through Wi-Fi and does not require an Aqara hub. ESPHome-based models usually connect directly to Home Assistant. Other consumer sensors may require Zigbee, Z-Wave, or a proprietary bridge.
Are presence sensors better than PIR sensors?
Not in every location. Presence sensors are better when someone may remain still, such as an office, bedroom, living room, or bathroom. PIR is often ideal for hallways, stairs, closets, and fast entry detection.
Can presence sensors save energy?
Yes, when they are used to turn off lighting, heating, cooling, or ventilation only after a room is truly vacant. Savings depend on the connected equipment, automation logic, and how the space is used.
