1. A method for securely controlling a remote measurement device, the method comprising the steps of:
establishing a connection between at least one remote measurement device and a server connected to the Internet, wherein the connection established between the at least one remote measurement device and the server is a tunnel connection which is established without a gateway;
protecting, by a firewall, the at least one remote measurement device from unauthorized access via the Internet;
sending, in case of an event of the at least one remote measurement device, an event notification from the at least one remote measurement device to the server via the firewall;
generating a temporary access token by the server in response to the event notification received from the remote measurement device; and
temporarily granting access to the at least one remote measurement device based on the temporary access token,
wherein the event represents an error state of the at least one remote measurement device or an end of a measurement procedure performed by the at least one remote measurement device.
