Python API for the Zevercloud API

Zevercloud API

Python API for the Zevercloud API

Note: This piece of software is not approved or endorsed by ZeverCloud. Nor do I endorse their products.

Installation

You can install zevercloud-api using your favorite package manager. For example:

pip install zevercloud-api

Credentials

Three keys are needed to connect to the Zevercloud API:

• api_key
• app_key
• app_secret

Your api_key can be found on the Zevercloud site, under Configuration > Plant Configuration > 5. Api Key. The app_key and app_secret can be found under Account Management > Security Settings, but are only visible once approved by Zeversolar Support. Send an email to [e-mail], for example, and ask them to make the app_key and app_secret visible to you. They typically do so within a day.

Usage

To see the last known status of your site, as well as some yield statistics:

from zevercloud import ZeverCloud

zc = ZeverCloud(API_KEY, APP_KEY, APP_SECRET)

print(zc.overview)

>>  {
        "last_updated": datetime(2022, 2, 3, 13, 57, 26),
        "online": False,
        "power": 0,
        "site_id": 12345,
        "yield": {
            "today": 5.9,
            "month": 218.42,
            "total": 5800,
            "year": 1770,
        },
    }

Historical power and yield

Historical yield and power figures can also be obtained:

zc.get_output(date=date(2022, 8, 1))

>>  [
       ...
        {"power": 1183, "timestamp": datetime(2022, 8, 1, 12, 0)},
        {"power": 1240, "timestamp": datetime(2022, 8, 1, 12, 20)},
        {"power": 1815, "timestamp": datetime(2022, 8, 1, 12, 40)},
        ...
    ]

zc.get_daily_output(month=date(2022, 8, 1))

>>  [
        {"date": date(2022, 3, 1), "yield": 4.1},
        {"date": date(2022, 8, 2), "yield": 5.2},
        {"date": date(2022, 8, 3), "yield": 0.2},
        ...
    ]

zc.get_monthly_output(year=2022)

>>  [
       {"date": date(2022, 1, 1), "yield": 40.1},
       {"date": date(2022, 2, 1), "yield": 52.1},
       {"date": date(2022, 3, 1), "yield": 113},
       {"date": date(2022, 4, 1), "yield": 8.11},
        ...
    ]

zc.get_yearly_output()

>>  [
       {"year": 2012, "yield": 4069},
       {"year": 2013, "yield": 308},
        ...
    ]

Power is always presented in W (Watt), and yield in kWh (kiloWatt-hour). Due to the internals of the Zevercloud API, all numbers may be rounded up to two significant digits.

Events

Events (errors) can be listed:

zc.get_events(start_date=date(2022, 1, 1), end_date=date(2022, 8, 1))

>>  [
        ZeverSolarEvent(
            event_time=datetime(2022, 1, 1, 12, 34, 56), 
            inverter_id="ZS12345678", 
            event_code=3, 
            event_type=101,
        )
    ]

The ZeverSolarEvent has a human-readable event_description.

Note: the internal Zevercloud API can only return events for 7 days at a time. Using the get_events-method on a large date range will result in many API-calls being made, and may hence possibly take a rather long time.
