Gateway and Communication

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

The various equipment connects to the Gateway via a serial bus (RS485-Modbus or MBus) or over an IP network (Ethernet or Wi-Fi).

Generally, a single Gateway is sufficient per building. For large sites with multiple buildings and when the various electrical rooms cannot be interconnected via bus or IP network, multiple Gateways are installed.

1. General Connection Options

The main equipment that connects to the Gateway includes:

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

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

2. Connection of the Gateway and Meters

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

The RS485 port allows direct connection of RS485-Modbus electric meters.

An RS485-MBus converter allows connection of heating and water meters using 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.

Currently, 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 Modbus TCP protocol.

Reading MBus Meters via RS485-Ethernet Converter

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