Best mmwave presence sensors 2026

If you’re building a local-first smart home, mmWave radar sensors are worth the extra cost over PIR motion sensors. Unlike passive infrared, mmWave detects micro-movements—breathing, typing, even slight posture shifts—so lights don’t cut out when you’re still. For Home Assistant, this means automations that actually work.

Why mmWave Matters for Presence Detection

PIR sensors have one job: detect heat moving across their field of view. Sit still for 90 seconds, and your bathroom light turns off. You’ve probably worked around this with long timeouts or motion boost buttons, but that’s a hack, not a solution.

mmWave radar sensors use frequency-modulated continuous wave (FMCW) radar to detect presence through distance, velocity, and even micro-movements. The tradeoff is price—good mmWave sensors run $40-150 versus $15-30 for PIR—but the reliability improvement is substantial.

One caveat: mmWave can struggle with certain materials like thick curtains, and some units have sensitivity issues near vibrating fans or HVAC vents. Placement matters more than with PIR.

Top Picks for Home Assistant

Aqara FP2

The Aqara FP2 remains the best balance of price, features, and local Home Assistant integration. It supports up to 3 zones (separate detection areas in one room), which is unique at this price point. Matter bridge via Aqara Hub M3 works well, and the entity naming in Home Assistant is clean. Expect to pay around $80.

The FP2’s main limitation is occupancy timeout—you can’t set it below 60 seconds. For some use cases that’s fine; for others it’s annoying. The FP1E addresses this but loses zone support.

Aqara FP300

If you want the latest Aqara and don’t need zones, the Aqara FP300 is the newer model with improved sensitivity and faster response. It’s Matter-certified out of the box, so no hub required if your setup supports Matter directly. Around $90.

Everything Presence One

The Everything Presence One from The Hook Up is designed specifically for Home Assistant with ESPHome. It exposes all the radar data—distance, movement speed, presence confidence—so you can build much more nuanced automations than with consumer sensors. Requires flashing ESPHome yourself, which is a barrier but gives you full local control. About $70 for the board, add $20-30 for enclosure and power.

The Everything Presence Lite is a simpler version if you just need basic occupancy without the extra data fields.

Third Reality Motion Sensor Matter

The Third Reality Motion Sensor Matter is worth mentioning if you want mmWave on the cheap. It’s not as refined as Aqara—response time is slower, and it occasionally false-triggers—but at around $35, it’s the budget option. Works well with Home Assistant via Matter.

What About Hubitat and HomeKit?

Hubitat users have fewer mmWave options. The Aeotec Smart Home Hub works with Aqara FP2 via the Aqara hub, but direct Zigbee mmWave support is limited. The FP2’s Matter bridge can work if you’ve added Matter support to Hubitat, though it’s not as smooth as Home Assistant.

For HomeKit, mmWave choices are nearly nonexistent. Eve Motion uses PIR, and Apple’s platform hasn’t embraced mmWave yet. If you’re all-in on HomeKit, stick with PIR or look at the third Reality sensor if they eventually add HomeKit support.

Quick Verdict

• Best overall: Aqara FP2 for most people—zones, solid integration, reasonable price
• Best for tinkerers: Everything Presence One for full data access and ESPHome control
• Best budget: Third Reality Motion Sensor Matter if price is the priority
• Best new: Aqara FP300 if you want Matter-native with better sensitivity

The gap between PIR and mmWave is real. If you’re tired of lights turning off while you’re reading, mmWave is the fix. Just plan your placement carefully—corner ceiling mounts typically work best.
