Welcome!
Thank you for choosing the TrickleStar TS1921 Occupancy Sensor.
This Occupancy Sensor is an accessory for the TrickleStar Wi-Fi Smart
Thermostat. The Sensor helps the Thermostat to maximize comfort to your
room as the sensor can detect occupancy as well as measure the temperature
in the room. Maximum 6 sensors can be connected to the thermostat via
bluetooth.
This Installation Guide describes how to install the Sensor and pair it to a
TrickleStar Wi-Fi Smart Thermostat.

Pairing the sensor
Step 1: Pull the plastic tag
To power up the Sensor, pull out the plastic tag from the Sensor gently.
When the Sensor is powered up, it enters Pairing mode automatically. The
LED starts blinking and continues blinking up to eight minutes.

If the LED does not blink after the Sensor is powered up or after battery
insertion or the Sensor exits Pairing mode after eight minutes, hold the Pairing
Button for 2 seconds to re-initiate pairing to the thermostat. The sensor will
enter Pairing mode again and broadcast itself for 8 minutes for thermostat
scanning. LED will blink briefly in the mode.
Step 2: Add Occupancy Sensor to the system
1.
Log in to your TrickleStar Portal account
at: portal.tricklestar.com You can also use the QR
code here.
2.
At Dashboard screen, select Devices, then click on your Thermostat Name
to enter Thermostat page.
3.
Select Sensors on the left panel, then click on “+” to add a new sensor.
4. Enter the name for your sensor.
5. Press Next once your sensor LED is blinking to complete the pairing process.
This will initiate a scan function and Thermostat will scan for sensors in range.
Sensors that are detected will be listed by their MAC addresses. User can
select from the list if there is more than one sensor to be paired and add the
sensors. Note: It may take up to 30 seconds to detect and pair a new sensor.
6. Once your sensor is successfully added, the Connection Status, Temperature
and Occupancy State will be “Not Used”. Wait for 1-2 minutes then click on
the "Refresh Sensor Data" button to update the sensor readings.

If pairing is successful, the LED will blink twice. Then, the Bluetooth indicator
appears on the Thermostat display.
If pairing is unsuccessful or time-out after 8 minutes, the LED will stop
blinking and the Sensor will go into standby mode. In Standby mode, the
connection between the sensor and the thermostat is not set up. All the
sensor circuits will be shut down to save power. Hold the Pairing Button for 2
seconds to initiate the Pairing mode again.
Note: If the sensor is previously registered, it will be added to the thermostat
network automatically in Pairing mode. The sensor LED will blink twice, then
Pairing mode finishes, and change to Normal mode. If disconnected, the
sensor will change to Pairing mode automatically and try to reconnect with
the thermostat. User can also press the pairing button to restart the sensor in
Pairing mode.

Mounting the Sensor on the wall
Before you mount the Sensor on the wall, be sure to check that:
•
The sensor is connected to the Thermostat.
•
The sensor is mounted away from direct heating or cooling sources, such
as a fireplace or an air ventilator.
Attach the double-sided adhesive to the Sensor. Then, mount the Sensor at a
height of approximately 5 ft. (1.5 m) on the wall.
5 ft.
(1.5 m)

11
Placing the Sensor on a flat surface
Before you place the Sensor on a flat surface, be sure to check that:
•
The sensor is connected to the Thermostat.
•
The sensor is placed on an even surface and at a safe location.
•
The sensor is facing the direction which you want to detect occupancy.
Attach the stand to the Sensor. Then, place the Sensor on a flat surface.

12
Ready for use
Normal mode
The Occupancy Sensor is now ready for use. In Normal mode, the connection
between the sensor and the thermostat is set up. The sensor will automatically
update the Connection Status, Room Temperature, Occupancy State and
Sensor Battery Level in the Tricklestar Portal and Tricklestar App.
You can enable or disable the sensor detection LED operation in Normal mode
through the TrickleStar Portal Sensor settings (Occupancy Detection LED). This
option also disables the sensor detection LED by default, meaning the sensor
LED will not blink when it detects a movement. If the LED is enabled, it will blink
once when there is a confirmed movement detection in every 30 seconds
interval.

13
Occupancy Detection
The occupancy sensor is equipped with an occupancy detection function. It
uses PIR sensor to detect the infrared signal of moving human bodies. You can
also enable or disable the occupancy detection function for each sensor
individually through the Portal or App. When disabled, the individual sensor
detection circuit will be shut off and the occupancy states will not be available.
You can adjust the Absence Detection Sensitivity and Occupancy Detection
Sensitivity, and enable or disable the Occupancy Detection feature of the
thermostat. If disabled, regardless of any sensor output and individual sensor
settings, the thermostat will ignore the occupancy status received and will not
automatically change the Mode. However, it will not shut off the sensor
detection circuit and you can still check the occupancy states for each sensor
through the Portal or App.
The occupancy detection feature is enabled if:
a)
The Occupancy Detection is set to Enabled at the Portal.
b)
The Occupancy Detection of each individual sensor is set to Enabled at the
Portal.
c)
The Sensor Status in the Portal is Connected.
d)
The active Mode is Home or Away (not Sleep).
e)
The Thermostat is on Schedule mode, not on
Temporary/Permanent/Vacation Hold or when user has changed the Mode
manually.

Occupancy detection algorithm
The thermostat changes the Mode automatically based on the received
occupancy states from the sensors:
If the Mode is “Home”
You can set the Absence Detection Sensitivity as shown in the illustration
above (Thermostat Sensor Settings). When the occupancy sensor detects no
movement within the Absence Detection Sensitivity time set, the Mode will
automatically change to “Away (set by sensor)” and follow your preset Away
Mode setting as shown below
:

17
If the Mode is “Away”
You can set the Occupancy Detection Sensitivity as shown in the illustration
above (Thermostat Sensor Settings). When the occupancy sensor detects a
movement within the Occupancy Detection Sensitivity time set, the Mode will
automatically change to “Home (set by sensor)” and follow your preset Home
Mode setting as shown below:

18
If the Mode is “Sleep”
The thermostat will not change the Mode.
To cancel the Mode change
Press jog dial for 3 seconds to return to Schedule Mode.
