Remote sensor and method for communication with a remote sensor

A method of communication between a remote sensor and an external device, the remote sensor including a first wireless interface for sending data, the method comprising:

• transferring energy from the external device to the remote sensor during configuration or maintenance of the remote sensor by the external device by a second wireless interface of the remote sensor, wherein the energy is used for operating the remote sensor,
• creating a communication link between the second wireless interface of the remote sensor and a wireless interface of the external device, wherein the second wireless interface of the remote sensor is arranged separately from the first wireless interface of the remote sensor for sending out data by using the energy received energy from the external device via the second wireless interface,
• controlling energy consumption of the remote sensor by use of an energy management unit, the energy management unit providing backup energy by a battery, and
• transmitting information (i) from the external device to the remote sensor and/or (ii) from the remote sensor to the external device by the established communication link.

A method of communication between a remote sensor and an external device, comprising:

• transferring energy from the external device to the remote sensor during configuration or maintenance of the remote sensor by the external device by a wireless interface of the remote sensor, wherein the energy is used for operating the remote sensor;
• creating a communication link between the wireless interface of the remote sensor and a wireless interface of the external device, wherein the wireless interface of the remote sensor is arranged separately from a further wireless interface of the remote sensor for sending out data;
• transmitting information (i) from the external device to the remote sensor and/or (ii) from the remote sensor to the external device by the established communication link;
• configuring or maintaining the remote sensor by the external device depending on the transmitted information, wherein a range of functions of the remote sensor and/or operating parameters of the remote sensor are influenced by one or more of activation, deactivation, readout, and modification;
• and wherein the external device is connected to an online service and obtains a release for the configuring or the maintaining of the remote sensor at the online service, the configuring or the maintaining of the remote sensor by the external device is only performed if the release has been obtained at the online service.
