mypermobil 0.1.7

A Python wrapper for the MyPermobil API

MyPermobil-API

This is a subset of the MyPermobil API, originally published to be used with HomeAssistant.

Installation

The package is available on pypi.org and installed with the command

python -m pip install mypermobil 

It can also be manually installed by

git clone  https://github.com/IsakNyberg/mypermobil.git
cd mypermobil
python -m pip install .

REST API

This API is a REST API that uses JSON as the data format. For most requests, the API requires an authentication token. The token is sent in the header of the request. The token can be created with the code in the example folder.

Endpoints

Supported endpoints are listed in the const.py, custom endpoints are also possible as arguments to the get and post methods. The available endpoints are:

GET regions
POST applicationlinks
POST applicationauthentications
GET battery-info
GET voiceaccess/dailyusage
GET voiceaccess/chargetime
GET voiceaccess/chairstatus
GET voiceaccess/usagerecords
GET /api/v1/products
GET /api/v1/products/{product_id}
GET /api/v1/products/{product_id}/positions

Some endpoints require a product id, this can be found in the PRODUCTS_ID item from the by using the GET ENDPOINT_PRODUCTS endpoint. This value can be set in the MyPermobil class.

MyPermobil Class

The MyPermobil class is the main class of the API. The class can store information needed for the requests and can be used to make requests to the API. The MyPermobil class uses aiohttp to make requests are they can be made asynchronously. The create_session function can be used to create a session without the need to import aiohttp. Just remember to close the session when it is no longer needed.

The minimum example of the class can be instantiated with:

session = create_session()
p = MyPermobil("application_name", session)
...
p.close_session()

To authenticate the app use the request_application_code() and request_application_token() methods. A detailed example can be found in the example folder.

If the app has already been authenticated, the class can be created with the data directly instead. The data will be locally validated with the self_authenticate() method.

    p = MyPermobil(
        application,
        session,
        email,
        region,
        code,
        token,
        expiration_date,
        product_id,
    )
    p.self_authenticate()

application, session, email, region, token and expiration_date are required to authenticate the app. The product_id is optional and can be set later.

Items

Items are lists that describe the path needed to traverse the JSON tree of the corresponding endpoint that is associated with the item. Each association is listed in the ITEM_LOOKUP with the reverse lookup in ENDPOINT_LOOKUP (however since items are not always unique, the ENDPOINT_LOOKUP will only return the first endpoint associated with the item).

An example is:

PRODUCT_BY_ID_MOST_RECENT_ODOMETER_TOTAL = ["mostRecent", "odometerTotal"]
ENDPOINT_PRODUCT_BY_ID = "/api/v1/products/{product_id}"

{
    "_id": "649adb...e377",
    "WCSerial": "48...28",
    "BrandId": "567...f50c",
    "lastUpdated": "2023",
    "mostRecent": {
        "odometerTotal": 386944,     <-----
        "odometerTrip": 375795,
    },
    "battery": {...},
    "serviceAgreements": [...],
    "certificates": [...]
}

In this scenario the PRODUCT_BY_ID_MOST_RECENT_ODOMETER_TOTAL item would return the value 386944 from the JSON tree.

Adding new items

Adding a new item can be done in the const.py file. The item should be added next to its endpoint and then in the the ITEM_LOOKUP dictionary. The item should be a list of strings or number with each step needed to take in the JSON tree. If the named with the following format:

ENDPOINT_ENDPOINT_NAME = "/api/v1/endpointname"
ENDPOINTNAME_ITEM_NEW = ["path", "to", "item", 0]

The item can then be added to the ENDPOINT_LOOKUP dictionary with the following format:

ITEM_LOOKUP = {
    ...
    ENDPOINT_ENDPOINT_NAME: [
        ENDPOINTNAME_ITEM_1,
        ENDPOINTNAME_ITEM_2,
        ENDPOINTNAME_ITEM_NEW,   <-----
        ENDPOINTNAME_ITEM_3,
    ],
    ...
}

Doing this will automatically add the item to the ENDPOINT_LOOKUP dictionary, if the item is unique.

The new item can then be accessed by using the request_item method in the MyPermobil class.

MyPermobil.request_item(ENDPOINTNAME_ITEM_NEW)

Or if the item is not unique and the endpoint needs to be specified:

MyPermobil.request_item(ENDPOINTNAME_ITEM_NEW, endpoint=ENDPOINT_ENDPOINT_NAME)

Async

All requests are made asynchronously. This means that the requests can be made in parallel. For every methods that uses the async keyword it must be awaited. This can be done by using the asyncio library. This was done in order to comply with Home Assistant.

import asyncio

async def main():
    await p.request_regions()

asyncio.run(main())

Caching

Many of the requests have the @cachable decorator. This decorator will cache the response of the request for 5 minutes. This is to prevent the API from being overloaded with requests, in particular when multiple items to the same endpoint is requested.
