SonnenCharger

Purpose

Read status information from a SonnenCharger type wallbox

Installation

Using pip

pip3 install sonnencharger

Manual installation

Download the archive from pypi.org and unpack where needed ;)

Usage

from sonnencharger import sonnencharger

sc_host = '192.168.1.2'
sc_port = 502  # optional, default=502

# Init class, establish connection
sc = sonnencharger(sc_host, sc_port)

print(sc.get_sysinfo())	    # retrieve general wallbox information
print(sc.get_connectors())  # retrieve status of the connectors
