# SMA Energy Meter Binding
|
|
|
|
This Binding is used to display the measured values of a SMA Energy Meter device.
|
|
It shows purchased and grid feed-in power and energy.
|
|
|
|
## Supported Things
|
|
|
|
This Binding supports SMA Energy Meter devices.
|
|
|
|
## Discovery
|
|
|
|
The Energy Meter is discovered by receiving data on the default multicast IP address.
|
|
|
|
## Binding Configuration
|
|
|
|
No binding configuration required.
|
|
|
|
## Thing Configuration
|
|
|
|
Usually no manual configuration is required, as the multicast IP address and the port remain on their factory set values.
|
|
Optionally, a refresh interval (in seconds) can be defined.
|
|
|
|
| Parameter | Name | Description | Required | Default |
