Method for communication between a communications interface module on the one hand and a telecommunications terminal on the other hand via a telecommunications network, the communications interface module being locally connected to at least one electrical device (31, 32, 36, 37, 38), the communications interface module having an identification module, the telecommunications terminal being a programmable telecommunications terminal having an application, at least one first message being transmitted to the communications interface module by the application of the telecommunications terminal, at least one second message being transmitted to the telecommunications terminal by the communications interface module, the first message and the second message being transmitted between the communications interface module and the telecommunications network on the one hand and the telecommunications terminal and the telecommunications network on the other hand - using an Internet Protocol connection, the communications interface module being identified by means of the identification module, the communications interface module having a fixed network interface and a mobile radio interface, a wired communications channel being used with use of the fixed network interface or a communications channel which is wireless at least in parts being used with use of the mobile radio interface for transmitting the first and/or second message between the communications interface module and the telecommunications network, the first and/or second message being transmitted - either using the fixed network interface - or using the mobile radio interface depending on the availability of the wired communications channel and/or the wired communications channel and as a function of a further parameter, characterised in that the further parameter, as a function of which the first and/or second message is transmitted either using the fixed network interface or using the mobile radio interface, is one or more parameters from the following list of parameters: - the transmission date of the first and/or second message, - the transmission time of the first and/or second message, - the state of the communications interface module, - the state of an electrical device (31, 32, 36, 37, 38) to which the communications interface module is locally connected, the communications interface module autonomously selecting the connection via available interfaces and protocols which best enables transmission of the first and/or second message. - using an Internet Protocol connection, the communications interface module being identified by means of the identification module, the communications interface module having a fixed network interface and a mobile radio interface, a wired communications channel being used with use of the fixed network interface or a communications channel which is wireless at least in parts being used with use of the mobile radio interface for transmitting the first and/or second message between the communications interface module and the telecommunications network, the first and/or second message being transmitted - either using the fixed network interface - or using the mobile radio interface depending on the availability of the wired communications channel and/or the wired communications channel and as a function of a further parameter, - the transmission date of the first and/or second message, - the transmission time of the first and/or second message, - the state of the communications interface module, - the state of an electrical device (31, 32, 36, 37, 38) to which the communications interface module is locally connected, the communications interface module autonomously selecting the connection via available interfaces and protocols which best enables transmission of the first and/or second message.
