Yes, you can. Simply follow the below steps. 

1. Log in with your personal credentials on the Valenco IoTUI Website.

2. On the top right corner please click on the button "Settings".

3. In the menu on the left side, please click on "trial information".

4. Here you can enter the respective Sensor ID. Alternatively, you can search for your trial via the list. 

5. Once you have successfully found the sensor, a menu on the right should open up where you can enter a new activation date in the field "Date and Time of Activation".

In case you do not know your sensor ID, you can look at the sensors manually. On the lid of the sensor, underneath the QR code, we have printed the last 4 digits of the sensor ID. This will be enough to find your sensor on the IoTUI.
