1. Charging Tucky


Before first use, charge your Tucky for at least 2 hours (the autonomy after 2 hours of charging is 5 days), using the USB cable provided. The red LED lights up during charging and goes out when charging is complete.

2. Download the application & create a user account (La Poste Host)

  1. Download the free Tucky application (On iOS: Apple Store or on Adroid: Google Play)
  2. Create a user account by following steps described below.

This “La Poste” account is necessary to monitor Tucky’s data remotely (beyond 10 meters) on other phones. This is a secure and certified health cloud (HADS).

1) Enter your favorite email address (e.g. xxx@gmail.com)

2) If the email address does not correspond to an existing La Poste account, fill in the fields.

3) If the email address corresponds to an existing La Poste account, enter your password.

Note 1: Don’t remember your password? Click on “Forgotten password” and follow the steps indicated.
Note 2: If the screen is white, please make sure that “javascript” is enabled in the browser settings.

3. Create a patient profile & associate Tucky

  1. Turn on Tucky by pressing the On/Off button; the LED will flash for 2 seconds (6 times).
  2. Create a patient profile, where you can enter the patient’s first and last name as well as age, gender, weight, date of birth, height and the level at which the fever alert is triggered.
  3. In the settings of your phone/tablet, activate the Bluetooth® function.
    Note: On iPhones, Tucky may not appear in the list of detected Bluetooth® devices. Simply turn on Bluetooth®, then exit your iPhone settings.
  4. In the application, select a profile, approach Tucky to the phone/tablet, press the “Pair” button and accept authorization requests. A temperature will be displayed in the banner.
    Note: Once associated, Tucky will reconnect as soon as it is within signal range.

PS: You can connect at least 6 Tucky at the same time on all types of smartphones (not entry-level).

  1. Remove the small part of the paper backing and peel the adhesive from the remaining part.
  2. Stick it to the front of the Tucky, covering the edges of the probe well.
  3. Remove both parts of the clear film.

5. Place Tucky under the right armpit


To place Tucky, observe the following points:

  1. The micro-USB port must face down with the tab-cap closed and the sensor skin side.
  2. It should be positioned as high as possible under the right armpit.
    Note: in case of hairiness, shave the area before applying the device.


For a better temperature measurement, wear light clothing and wait approximately 15 minutes with the arm closed until the temperature stabilizes.

PS: in case of heavy sweating and/or sports activity, here are the recommendations: 

For better support, we recommend applying single-sided adhesive tape over Tucky.

  • Cut a 2 cm strip of adhesive tape to a length of 10 cm.
  • Apply it over Tucky as shown in step C* below.

The live Bluetooth distance is about 10 meters (from room to room).

The remote connection is possible using 2 devices (tablet / smartphone) :

  • 1 “relay” device, designed to stay close to the child (5-10m) and transmit data to the cloud.
  • 1 for remote monitoring, which displays information from the cloud
