SmartThings Sensors and Controls for EP1

SmartThings Sensors and Controls for EP1

Everything Presence One appears in SmartThings with separate tiles for its main sensors and controls.



Main tiles

Tile

What it means

Best use

Presence

Overall room occupancy from the device

Use this for most automations

PIR Motion

Motion detected by the PIR sensor

Fast movement detection

mmWave Presence

Presence detected by the mmWave sensor

Stillness and fine presence detection

Temperature

Current room temperature

Climate automations and monitoring

Humidity

Current room humidity

Ventilation and comfort automations

Illuminance

Current light level

Lighting automations

LED

Status LED control

Turn the device LED on or off

CO2

Carbon dioxide reading in ppm

Air quality automations, when the CO2 module is installed

Calibrate CO2 (Outdoor Air)

Starts CO2 outdoor-air calibration

Only use with the device in fresh outdoor air

CO2 and Calibrate CO2 (Outdoor Air) only appear when the CO2 module is installed, EP1 is running CO2-enabled firmware, and SmartThings has detected the CO2 sensor. EP1 does not currently show a Restart Device tile in SmartThings.

Which motion tile should I use?

Use Presence for normal room occupancy automations. It is the easiest tile to understand and is designed to represent whether the room is occupied.

Use PIR Motion when you specifically want quick movement detection.

Use mmWave Presence when you want to see whether the radar is detecting presence separately from the PIR sensor.

Settings

EP1 settings in SmartThings include:

  • Device address and port

  • Occupancy off delay

  • PIR motion off delay

  • Temperature offset

  • Humidity offset

  • Illuminance offset

  • Settings for tuning the mmwave sensor - see How to Tune Your EP1 Sensor



These settings are useful for small adjustments without leaving SmartThings.

CO2 calibration

The CO2 calibration tile appears when the CO2 module is installed, EP1 is running CO2-enabled firmware, and the sensor has been detected by SmartThings.

To calibrate:

  1. Move EP1 into fresh outdoor air, or place it next to an open window with strong outdoor airflow.

  2. Power the device and leave it running for 3-5 minutes so the CO2 reading can settle.

  3. In SmartThings, open the EP1 device.

  4. Press Calibrate CO2 (Outdoor Air) once.

  5. Leave EP1 in fresh air for another few minutes before moving it back indoors.

Do not calibrate while the device is indoors, near people breathing on it, or in a poorly ventilated space. A bad calibration can make future CO2 readings inaccurate.

For module setup details, see Integrate the Carbon Dioxide (CO2) Module for EP1.

Notes

SmartThings shows the most useful EP1 controls for everyday automations. Firmware updates, advanced diagnostics, and deeper tuning should be done using the recommended device tools for your setup.
