Abstract: An automatic reading system (ARS—1) determines values at a plurality of distributed installation locations and communicates data containing said values via a low power wide area Network (LPWAN) to a head-end-system (HES—3). The ARS includes the HES and battery-powered stationary measuring devices (7), configured to be installed at an installation location and to determine said values at the installation location. The measuring devices include an LPWAN connection module to establish a wireless values communication connection via the LPWAN to the HES. A mobile installation device (13) includes a short-range connection module establishing a communication connection (15) and sending candidate information to measuring devices about to be installed at the installation location. The LPWAN connection module attempts to establish for the first time at the one of the installation locations a handshaked LPWAN connection to the LPWAN based on the received LPWAN connection candidate information.
