– Stand-alone mode (DLM)
The Webasto Next has a local, dynamic load management
stand-alone function. Here, one smart meter per Charging Sta-
tion is connected to the wall box via a router or DHCP switch.
2.
This communication makes use of the Modbus TCP protocol via
the RJ45 port. A connection between the wall box and router
can also be made using WLAN, but this setup is not recommen-
ded when using a smart meter on account of the potentially un-
stable connection.
A list of compatible smart meters can be found at https://char-
ging.webasto.com/en-uk/products/webasto-next/.
The DLM communication protocol for the Webasto Next can be
enabled in the Setup app https://charging.webasto.com/en-
uk/products/webasto-next/ or via the integrated WebUI
chapter 9, "WebUI" on page 12.
Alternatively, the Webasto Next can be connected to the smart
meter directly using an Ethernet cable. However, this type of
connection is not recommended as both devices required a
static IP address.
NOTE
Assign a static IP address to all Webasto Next wall
boxes using the settings on your Internet router.
There are two possible locations for the smart meter in the
house:
1. Smart meter before wall box (including wall box).
