And below, the next protocols :

The gateway uses this wireless interface, which operates in the ISM 868 Mhz bandwidth, to collect the data from the temperature or sunshine sensors, On/Off inputs/outputs and from the pulsed or electronic meters.

From a configuration file and/or local HTML interface, which describes all the equipment comprising the plant (inverters, meters, sensors, etc.), the gateway scans and collects the data related to each item of equipment. This data is then formatted (csv) and sent periodically over the GPRS, Ethernet or telephone network to a central server. According to the status of some of these variables, alarms may be triggered and sent by the system in real time. Conversely, the WebdynSun gateway can receive command files from the central server to operate the actuators. All the gateway's functions can be synchronised with the server using Web services.
