The Smart Gateway is a gateway to the Smart cloud service for all Smart-compatible devices and for some devices connected to the Modbus. One Smart Gateway device and an Internet connection is necessary for each installation location (wash station). Due to the cloud service, you do not need static IP-addresses or separate firewall devices for remote monitoring.
Even more than 200 devices (typically under 10) can be connected to the gateway. In addition to the gateway, you will need a 24VDC power source, which will be scaled individually (1A/device).
The Smart Gateway operates on the reliable and safe operating system, Linux.
