Common issues and solutions for Everything Presence One.

ESP32 LED Flashing

The LED on the main EP1 board will flash if:

  • The device is not connected to WiFi, OR

  • The device is connected to WiFi but Home Assistant has not connected to the EP1

This is normal during initial setup. The LED will stop flashing once Home Assistant successfully connects to the device.

Sensor Not Appearing in Home Assistant

Check WiFi Connection

  1. Ensure the EP1 is powered (LED behaviour explained above)

  2. Verify your WiFi network is 2.4GHz (EP1 doesn't support 5GHz)

  3. Check that the EP1 is within range of your router

  4. Try a different power supply - poor quality or noisy USB power supplies can cause WiFi connectivity issues

Re-adopt the Device

  1. Go to Settings > Devices & Services > ESPHome

  2. Look for a new device to configure

  3. If not visible, try power cycling the EP1

Check ESPHome Logs

  1. In Home Assistant, go to your EP1 device

  2. Click the three dots menu > Logs

  3. Look for connection errors or WiFi issues

Entity Shows "Unavailable"

This usually indicates a connection issue between Home Assistant and the EP1.

Solutions:

  • Power cycle the EP1 (unplug and replug)

  • Try a different power supply - noisy power supplies can cause intermittent disconnections

  • Check your WiFi router for connection issues

  • Restart Home Assistant

  • Check ESPHome logs for errors

Sensor Stuck on "Detected"

The sensor reports presence continuously even when the room is empty.

Common causes and fixes:

Cause

Solution

Poor quality power supply

Try a different USB power adapter

Ceiling fan in detection range

Reduce max distance or reposition sensor

Detecting through thin walls

Reduce max distance setting

HVAC vents causing movement

Aim sensor away from vents

Reflective surfaces

Reposition to avoid mirrors/glass

Vibrating mount surface

Mount on a stable, solid surface

Tuning steps:

  1. Reduce Max Distance to match your room size

  2. Lower Sustain Sensitivity (try 4-5)

  3. Increase On Latency to filter brief triggers

Sensor Stuck on "Clear" / Not Detecting

The sensor doesn't detect presence when someone is in the room.

Solutions:

  1. Check your power supply - noisy power can affect mmWave sensor performance

  2. Increase Max Distance to cover the full room

  3. Increase Sustain Sensitivity (try 7-8)

  4. Reduce On Latency to 0 for fastest response

  5. Check sensor placement - avoid obstructions

  6. Ensure the sensor is pointed at the detection area

False Positives from Pets

The EP1 will detect pets that move within its range.

Options:

  • Reduce Max Distance to exclude floor level

  • Mount higher and angle downward

  • Adjust Trigger Distance for initial detection threshold

  • Use On Latency to filter brief movements

Detecting Through Walls

mmWave can penetrate thin walls and detect movement in adjacent rooms.

Solutions:

  1. Reduce Max Distance to stop before the wall

  2. Reposition the sensor to aim away from thin walls

  3. Use Trigger Distance as a secondary threshold

Temperature/Humidity Readings Incorrect

Calibration:

  • Use the Temperature Offset and Humidity Offset controls

  • Compare readings with a known accurate thermometer

  • Allow 24 hours for the sensor to acclimate after installation

mmWave LED Flashing Constantly

This is normal - the LED indicates the sensor is actively scanning.

To disable:

  1. Find the mmWave LED entity in Home Assistant

  2. Turn it off

Settings Don't Take Effect

For EP1, you must press the apply buttons after changing settings.

Remember to press:

  • Set Distance after changing distance values

  • Set Sensitivity after changing sensitivity values

Wait 10 seconds between changes. The mmWave sensor needs time to apply each setting. If you change multiple settings too quickly, some may not be saved correctly.

Reset WiFi Settings Using the Boot Button

If you need to reset the WiFi settings (for example, to connect to a different network), you can use the boot button on the EP1 board:

  1. Locate the BOOT button on the EP1 PCB

  2. Perform this sequence:

    • Press and hold for 1 second, then release

    • Press and hold for 1 second, then release

    • Press and hold for at least 5 seconds

  3. The LED will flash 5 times to confirm the reset

  4. The device will restart with WiFi settings cleared

After resetting, follow the Set up your EP1 device in Home Assistant guide to reconfigure your device.
