sigen 3.0.3

Sigen

Unofficial package for reading and writing data to and from Sigenergy inverters via cloud APIs.

Version 3.0.0 - Updated to support v3 app APIs for modes and smart loads.

Installation

pip install sigen

Usage

from sigen import Sigen

# username and password you use in the mySigen app.
# Region is Europe (eu) / Asia-Pacific (apac) /
# Middle East & Africa (eu) / Chinese Mainland (cn) / Unitest States (us)
sigen = Sigen(username="your_username", password="your_password", region="eu")

# 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 default 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_mode_fully_fed_to_grid())

# Set custom modes (if available)
print(await sigen.set_operational_mode_summer_50kwh())

# Get and control smart loads
smart_loads = await sigen.get_smart_loads()
for load in smart_loads:
    print(f"Smart Load: {load['name']} - Power: {load['valueWithUnit']}")

# Control smart loads (using path value)
print(await sigen.set_smart_load_state(1, 1))  # Turn on smart load with path 1
print(await sigen.set_smart_load_state(1, 0))  # Turn off smart load with path 1

# Or use convenient dynamic methods (generated from available smart loads)
print(await sigen.enable_smart_load_immersion())   # Turn on
print(await sigen.disable_smart_load_immersion())  # Turn off
