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.
EP1 with CO2 sensor installed
To calibrate:
Move EP1 into fresh outdoor air, or place it next to an open window with strong outdoor airflow.
Power the device and leave it running for 3-5 minutes so the CO2 reading can settle.
In SmartThings, open the EP1 device.
Press
Calibrate CO2 (Outdoor Air)once.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.
