What are the network requirements in order to connect the Maxem Energy Controller

Follow below instruction to ensure a proper connection between the Maxem Energy Controller and the Maxem server

Network requirements / instructions

The following requirements are necessary for a properly functioning connection between Maxem and our Maxem server. Don’t be alarmed by the technical terms—these are standard networking requirements. On corporate networks, some of these settings may occasionally be blocked.

  • Maxem must receive an IP address. This can be via DHCP or a static IP address, depending on your network. In the case of a static IP address, you can assign it to Maxem yourself via the router.

  • Maxem must not receive an IP address in the range 192.168.25.X.

  • For MX4, the IP range must not fall within 10.50.X.X.

  • For MX4, the IP range must not fall within 10.51.X.X.

  • For MX5, the IP range must not fall within 10.40.X.X.

  • For MX5, the IP range must not fall within 10.41.X.X.

  • For MX5, the IP range must not fall within 10.0.0.X.

  • If a firewall is present on outgoing traffic, ports 53, 80, 123, 443, 1192–1200, and 9090 must be open.

  • The router or modem must support MTU = 1500.

  • The firewall must not include DNS rebind protection.

Important: Certain devices connected to your network (e.g., Sonos speakers) may block Maxem’s internet connection to our Maxem server.

Explanation of the network requirements:

Maxem has a separate port with its own DHCP server that assigns IP addresses to charging stations in the range 192.168.25.X. If Maxem receives an IP address from your network in this same range, a conflict arises and Maxem cannot connect to the Maxem server.

Maxem’s DHCP server does not affect your network, since Maxem is connected to your network via a different network port (marked “LAN”). Use of any of the other mentioned IP ranges can cause conflicts with the VPN that Maxem is part of. This will prevent Maxem from connecting to the Maxem server.
