PowerCable MQTT 101x periodically connects to the specified server over http / https and sends data in a .xml (EXtensible Markup Language) structure.

The communication is one-way only; it can only be used for the measured values.
- The frequency of connecting to the server can be set as short as 10 seconds.
- XML over http(s) can use the standard port 80 (enabled in most internal networks).
- The HTTPs version uses SSL encryption.
