Remote operation

The web server can be operated from a PC with web browser on a local area
network (LAN) or via the Internet. The following settings also apply to access via
Smartphone and other apps via Web API.
6.1.1

Local area network (LAN)

The PC and web server must be on the same IP subnet to communicate. You must
first determine the subnet as well as the IP addresses.
A router normally serves as the DHCP server if installed on a local area net-
work (e.g. DSL router for Internet access). As such, it automatically assigns
IP addresses to all participants that are DHCP clients.
If a PC is connected to the router via Ethernet, an IP address, subnet mask,
standard gateway and DNS server are assigned automatically.
When delivered, the web server already contains an enabled DHCP client;
as a result, users do not need to enter Ethernet settings.
The connection is checked every 3 minutes. It is recommended to assign the
IP address of the web server in the router according to its MAC address.
If the router with DHCP server is not available, the web server uses the default
IP address 192.168.2.10.
