Ensuring C10/C50 internet connectivity

Description

The temperature measurements are wirelessly sent to a central point, which is the Gateway (E.g. C10 - Ethernet Gateway or C50 - WiFi Gateway). These gateway forwards the measurements to the cloud. The Gateway is typically located in the office and requires a 220V power outlet and a network connection or a WiFi connection. This document describes how to successfully connect the Gateway to the server. 

The Gateway attempts to create an outgoing internet connection to the RmoniWeb server on the internet. So it effectively behaves like a computer on your network, trying to reach a website on a server. This means it must be connected on your network and must be allowed to connect to the server.

Things to check in advance

Make sure to check the following things during an installation:

• Network port connection (C10 - Ethernet Gateway)
  Make sure a network port is available in the office. Check if this network port is connected to your network. E.g. plug in a computer, switch off the Wi-Fi and try to surf on the internet. If this doesn’t work than check if the network port is connected to the network switch in the patch panel.

• WiFi connection (C50 - WiFi Gateway)
  Make sure a WiFi network is available, which should have an SSID and Password. Try to connect a computer or tablet via this Wifi access.  

Things to check during installation

Make sure to check the following things during an installation:

• Network connection
  Plug the gateway into the network port, plug in the power adapter. Check if the orange light (at the network connector) is on (continuously). Is this not the case? Check the cabling or try another port.

• Network connection - Wifi
  Plug the power adapter into the Wifi Gateway

• Server connection
  Check the LEDs on the front of the gateway. the green led (server) will blink for a few seconds before it turns on green continuously to indicate a successful connection to the server. Is this not the case? Please check out our detailed description below and ask your IT staff for assistance when required.

Detailed IT description

The Gateway has to receive an internal IP address on the LAN and also has to be allowed to create an outgoing TCP connection to the RmoniWeb server. The requirements are: :

• IP address
  The Gateway will ask an IP address via DHCP by default. If this is not supported on your LAN, please provide an IP address which can be pre-programmed into your Gateway.
  
  
• MAC address
  If the MAC address has to be white-listed on your LAN, please make sure to look for the Ethernet MAC Address which is noted on the log-in documents. Do not use the MAC address sticker on the side of the gateway (this is a Zigbee MAC address).
  
  
• TCP connection
  The gateway will try to make an outgoing connection to dns4.sensor2web.com at port 6337. Please, see below if DNS is not supported.
  
  
• DNS
  If DNS is not supported on your LAN, than please let us know in advance. We will than pre-program the target IP address 185.2.52.85 at port 6337.
  
  
• Firewall
  Please, add the following firewall rule if your firewall blocks outgoing TCP connections:
  
  

ALLOW [RAW TCP] from [internal IP] to 185.2.52.85 at port 6337

• Ethernet (C10)
  Standard 10/100 Mbps Ethernet raw TCP
  
  
• WiFi (C50)
  Requires an SSID with password. Protection base can be AES PSK or Enterprise. Cannot have a landing page (such as a guest wifi)

• Bandwidth
  The sensor measurements are very small, typically less than 100 bytes sent every 5 minutes. So even with a sensor network of 20 nodes, the data traffic generated is neglectable.
