System Requirements

Router

The router connects the Sunny Home Manager via the Internet to Sunny Portal.

SMA recommends a permanent Internet connection (flat rate) and the use of a router that supports the dynamic assignment of IP addresses (DHCP ‒ Dynamic Host Configuration Protocol), e.g. a Fritz!Box.
All network components used must support the IGMP protocol, minimum version 3 (IGMPv3). If Ethernet network switches are used in the system, make sure that they do not perform "IGMP snooping". This is the case with most simple switches; this function must be turned off for higher-quality "managed" network switches. Using media couplers such as powerline adaptors can cause transmission problems. Usually, a firmware update of the manufacturer makes these devices compatible with multicast operation.
