SMA-EM Plugin
This plugin retrieves the data sent by the SMA Energy Meter. In agreement with the author Florian Wenger, this plugin uses code published in https://github.com/datenschuft/SMA-EM/ - especially the readem method.
Forum thread to the plugin: https://knx-user-forum.de/forum/supportforen/smarthome-py/1030610-sma_em-plugin
The SMA Energy Meter broadcasts its information via multicast to the network address 239.12.255.254. Beyond the items supported by this plugin, the readem method allows for a lot more of parameters. The items will be extended in future versions of this plugin on demand. The available values can be seen in the readem method of this plugin.
If demand exists, the plugin can also be extended to be used with more than one energy meter.
The new version of the Plugin has been completely adapted to the changes in the datagram as documented in http://www.eb-systeme.de/?page_id=3005.
Configuration
plugin.yaml
sma_em:
class_name: SMA_EM
class_path: plugins.sma_em
serial: xxxxxxxxxx
cycle: 5
Attributes
serial: The serial number of your energy metercycle: The time in seconds to wait after a multicast was received. I introduced this to avoid too many values to be processed.
