Main tiles

Tile

What it means

Best use

Presence

Overall room occupancy

Use this for most room-level automations

Zone 1 to Zone 4

Whether each configured zone is occupied

Area-specific automations

Target count

Number of tracked targets in a zone

More precise zone logic

Target 1 to Target 3

Whether each radar target slot is active

Diagnostics and advanced routines

Illuminance

Current light level

Lighting automations

LED

Status LED control

Turn the device LED on or off

Restart Device

Restarts the device

Use when troubleshooting

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, EPL is running CO2-enabled firmware, and SmartThings has detected the CO2 sensor. Temperature and humidity are not shown for EPL in SmartThings.

Which tile should I use?

Use Presence for normal room occupancy automations.

Use Zone 1 to Zone 4 when you want different actions in different parts of a room, such as a desk area, sofa area, or doorway.

Use Target 1 to Target 3 for diagnostics or advanced automations. These are radar target slots, not named people.

Zone setup note

SmartThings can use EPL zones once they are configured, but it is not a visual zone editor. Use Zone Configurator when you need to draw or adjust room zones.

CO2 calibration

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

[Image placeholder: EPL with CO2 module showing the CO2 reading and Calibrate CO2 tile]

To calibrate:

  1. Move EPL 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 EPL device.

  4. Press Calibrate CO2 (Outdoor Air) once.

  5. Leave EPL 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.
