FusionSolarPy

A very basic python client for the HuaweiFusionSolar API used to monitor solar power plants.

This client uses the https://region01eu5.fusionsolar.huawei.com end point by default. It is possible to change this using the huawei_subdomain parameter. But this has not been tested on any other end-points.

Please report any bugs!

Installation

Simply install from pypi using:

pip install fusion_solar_py

Usage

The basic usage centers around the FusionSolarClient class. It currently only has one method to extract the current power production, the total power production for the current day, and the total energy ever produced by the plant.

from fusion_solar_py.client import FusionSolarClient

# log into the API - with proper credentials...
client = FusionSolarClient("my_user", "my_password")

# NOTE: Depending on your region, you may need to set the
# `huawei_subdomain` parameter. This is the first part of the
# URL when you enter the FusionSolar API through your webbrowser
#
# client = FusionSolarClient("my_user", "my_password", huawei_subdomai="region01eu5")

# get the stats
stats = client.get_power_status()

# print all stats
print(f"Current power: {stats.current_power_kw} kW")
print(f"Total power today: {stats.total_power_today_kwh} kWh")
print(f"Total power: {stats.total_power_kwh} kWh")

# log out - just in case
client.log_out()

It is additional possible to retrieve the data for specific plants - in case multiple plants are available through the account.

from fusion_solar_py.client import FusionSolarClient

# log into the API - with proper credentials...
client = FusionSolarClient("my_user", "my_password")

# get the plant ids
plant_ids = client.get_plant_ids()

print(f"Found {len(plant_ids)} plants")

# get the data for the first plant
plant_data = client.get_plant_stats(plant_ids[0])

# plant_data is a dict that contains the complete
# usage statistics of the current day. There is
# a helper function available to extract some
# most recent measurements
last_values = client.get_last_plant_data(plant_data)

print(f"Last production at {last_values['productPower']['time']]}: {last_values['productPower']['value']}")

# In case you have a battery installed
print(f"Last battery charge at {last_values['chargePower']['time']}: {last_values['chargePower']['value']}")

# log out - just in case
client.log_out()
