Project description
Sigen
A package to reading and writing data to and from Sigenergy inverters.
Installation
pip install sigen
Usage
from sigen import Sigen
# username and password you use in the mySigen app.
sigen = Sigen(username="your_username", password="your_password")
# Read data
print(sigen.fetch_station_info())
print(sigen.get_energy_flow())
print(sigen.get_operational_mode())
# Set modes
print(sigen.set_operational_mode_sigen_ai_mode())
print(sigen.set_operational_mode_maximum_self_powered())
print(sigen.set_operational_mode_tou())
print(sigen.set_operational_fully_fed_to_grid())
