The USB port stays reserved until the installer closes.
ESPectre measures how the Wi-Fi waves changes as people move.
Processing runs locally on a supported chip of ESP32 family.
No cameras, microphones, or external processing needed.
Run a browser tool, learn how ESPectre works, or evaluate it for your product.
Turn a supported ESP32 into a Wi-Fi motion sensor over USB.
Open Flash → CONFIGUREConfigure the device over its local Direct WebSocket.
Open Configure → MONITORUse Direct WebSocket or MQTT to inspect motion, tune detection, and view diagnostics.
Open Monitor →Flash, configure, and explore motion sensing from the browser.
Install ESPectre firmware over USB from a supported desktop browser.
Open →
Set Wi-Fi, optional MQTT, and the device name over Direct WebSocket.
Open →
Watch live sensing, tune detection, and inspect diagnostics over the broker.

Explore whether micro-motion can distinguish an occupied quiet room from an empty one.
On the roadmap →
Explore whether breathing-related micro-motion can become a reliable local sensing signal.
On the roadmap →
Explore whether high-rate sensing can recognize brief gestures reliably.
On the roadmap →Pick a firmware, plug the board into USB, and install. The installer detects the chip over serial.
USB flashing requires desktop Chrome or Edge.
Provision Wi-Fi through the USB flasher, then connect to the local device to set the BSSID, optional MQTT, and the device name.
Enter the device IP address or its espectre-<device-id>.local name.
Your browser may ask for Local network access. Allow it for this site. If a .local name does not resolve, use the device IP address.
Changing the band is saved immediately and takes effect after restarting the device.
Use Direct WebSocket for one device on this LAN, or choose MQTT for Home Assistant, automation, remote access, and multiple devices.
Broker-free monitoring for one Native device on the same LAN.
Allow Local network access if prompted. If a .local name does not resolve, use the device IP address.
Use the broker to open live sensing, controls, and diagnostics.
Port 9001; HTTPS requires trusted WSS.
Movement score versus threshold, last 60 seconds.
Changes are sent to the device immediately.
Keep the room quiet while the detector establishes a new baseline.
Turn live MQTT motion energy into sound, or explore the interaction in demo mode.
The theremin turns live motion energy into sound. Start sensing from Monitor, or run the demo.
Audio starts only after you press play.
Move to fly, stay quiet to descend, and steer the Spectre through the course.
Your body is the controller: movement makes the Spectre fly, and quiet brings it back down. Start sensing from Monitor, or run the demo.
Flight line 0.50. It starts at 0.50 whenever you open the game. Drag to retune this game only; the device threshold does not change.
