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 for each building. For large sites with multiple buildings and when the different electrical rooms cannot connect to each other via a bus or IP network, multiple Gateways are installed.

1. General connection options

The main devices connecting 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 shows the various components that can be connected to the Climkit Gateway.

2. Connecting the Gateway and meters

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

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

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

3. Cloud Gateway connection

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

For now, this configuration is only possible for reading electrical 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.
