Hello, bmaks ,
You can use the phone as a tracker for this you need to install one of the WiaTag or Traccar Client applications.
To further configure using the WiaTag application, you need to do the following:
1) Create an unit, category and type of tracker in the application Ruhavik - Software - WiaTag, name - any, password - any, for the identifier you can take the IMEI of your phone or come up with an identifier
2) After creating the unit, you will receive a QR code. It will be displayed in the application.
3) Now go to WiaTag app and login with QR code. You just need to scan it for Wiatag to be configured for your Ruhavik unit.
4) Now in Ruhavik you should see the location of your phone.
