Gateway and Communication

The Climkit Gateway is the central communication hub for all Climkit solutions.

The various devices connect to the Gateway via a serial bus (RS485-Modbus or MBus) or via an IP network (Ethernet or WIFI).

Generally, a single Gateway is sufficient per building. For larger sites with multiple buildings and where the different electrical rooms are not connectable via bus or IP network, multiple Gateways are installed.

1. General connection options

The main devices that connect to the Gateway are:

  • Meters (RS485-Modbus and MBus)
  • Charging stations for electric vehicles (Ethernet or WiFi)
  • RFID readers (Ethernet)
  • Relays and other control modules (RS485-Modbus, Ethernet, or WiFi)

The diagram below indicates the various elements that can be connected to the Climkit Gateway.

2. Connecting the Gateway and the meters

The Gateway connects to the internet via a 4G router or via a local internet connection if available.

The RS485 port allows for direct connection of RS485-Modbus electrical meters.

An RS485-MBus converter allows for the connection of heating and water meters with the MBus communication protocol.

3. Cloud Gateway connection

In some cases, it is possible to forgo a Gateway by installing a 4G router or LAN router and an RS485/Ethernet converter.

For now, this configuration is only possible for reading electric meters that communicate via the Modbus protocol.

4. Modbus TCP / MBus TCP Communication

Climkit Gateway with RS485-Ethernet converter

It is also possible to read meters with the Climkit Gateway using an RS485-Ethernet converter with the ModbusTCP protocol.

Reading MBus meters via the RS485-Ethernet converter

It is also possible to read heating and water meters (MBus) with the Climkit Gateway using an RS485-Ethernet converter.
