It is an extra WiFi module, which is installed and paired to the CcM2, CcM3 and CcM4 devices and enables conversion of all the CcM-485 devices to WiFi devices, thus allowing them to become isolated without losing the possibility to connect to other CcM devices through an RS-485 cable at the same time and keep a single network of devices interconnected (sub-metering) via cable. It automatically sends electrical data from the device, within which it is embedded, every 10 seconds through a cloud (Cloud mode) or through an FTP connection; or it receives requests remotely using and IP connection (Gateway mode).
This solution was designed to work in isolation from the rest of the CcM smart meter, it is perfect for household or isolated installations. It measures the energy, which circulates in one or both phases of a one or two-phase magnet, it communicates using WiFi.
The CcM-WiFi is one of the devices in the CcM family range, which connect to the main devices CcM2, CcM3 and CcM4 from the CcM smart meter to provide them with wireless connectivity, thus allowing them to keep the 485 connection between the main devices in Gateway mode and secondary devices (CcM1-C) in Cloud mode .
The CcM product range consists of a set of devices used for the monitoring of electrical parameters inside the electrical switchboard in single- and three-phase installations. They are best suitable for installation in thermal-magnetic switches or residual-current circuit breakers to obtain multiple measures in multiple points and to be physically interconnected using a 485 cable to a sub-metering design.
The CcM smart meter devices offer multiple configuration options and allow users to configure the most convenient solution for both, their domestic and industrial installations. Installations can be wireless or connected with a communication cable. The devices can be connected to each other and create communication buses, establishing configurable master-slave hierarchies.
With the device or external module CcM-WiFi, the user may easily access the data collected by the main devices of the CcM product range using WiFi simply by directly connecting to the CcM smart metering in question using plug & play, adapted to the physical shape of the main devices and without need for external power supply outside the one provided by the device within which it is embedded.
Thanks to the wireless connection (WiFi) provided by the CcM-WiFi module, it is possible to send requests to the devices using the Modbus commands (Gateway mode) or allow that the CcM smart meter itself requests the metering data from the device, which stores them and sends them to the default server (EnergyCcM) in Cloud mode and every 10 seconds or which sends them to an external server in FTP mode.
The best way to configure a WiFi device from the CcM family is using the EnergyCcM App or by accessing the internal website of the WiFi device using its address.
The only other way to establish a direct communication with the CcM smart building devices without using this device or the CcM-WiFi adaptor would be using a cable connection RS-485 with any data collection programme, which would send requests to the devices using the Modbus RTU protocol, by using one of the offered software tools or via one of the free of charge software tools such as the CcManager (configuration, visualisation and storing in the local network through a PLC window or Linux or directly with the CcMaster) or in the Energy CcM web portal (visualisation and storing of the data in the cloud using CcM-WiFi).
