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=username, password=password)

# Initialize the Sigen instance
await sigen.async_initialize()

# Read data
print(await sigen.fetch_station_info())
print(await sigen.get_energy_flow())
print(await sigen.get_operational_mode())

# Set modes
print(await sigen.set_operational_mode_sigen_ai_mode())
print(await sigen.set_operational_mode_maximum_self_powered())
print(await sigen.set_operational_mode_tou())
print(await sigen.set_operational_fully_fed_to_grid())
