Communication with distributed devices handling electric energy via the internet

A method of communication of distributed devices handling electric energy with communication partners via the Internet, the method comprising:

• providing a server;
• programming rules in the server, the rules determining between which at least one device of a plurality of devices and which at least one communication partner of a plurality of communication partners a communication connection is to be mediated based on generic properties of the devices, generic properties of the communication partners and an initializing time-variable datum, the communication connection being selected from a group of connections consisting of point to point, point to multi point and multi point to multi point connections via the Internet;
• transmitting data from each device to the server via the Internet, the data including both a communication address and attributes indicative of the generic properties of the respective device;
• transmitting further data from each communication partner to the server via the Internet, the further data including both a communication address and attributes indicative of the generic properties of the respective communication partner;
• and
• mediating the communication connection between the at least one device and the at least one communication partner determined by the rules in response to a value of the initializing time-variable datum and the programmed rules.
