# Add support via a dedicated source
|
|
|
|
## Files required for a new Service Provider
|
|
|
|
The following files need to be provided to support a new service provider:
|
|
|
|
- A python `source script` that retrieves the collection schedule information, formats it appropriately, and has test cases that can be used to confirm functionality.
|
|
- A `source markdown (.md)` file that describes how to configure the new source and sensor, with examples.
|
|
- An updated `README.md` file containing details of the new service provider. This file will be automatically updated by a script.
|
|
- An updated `info.md` file containing details of the new service provider. This file will be automatically updated by a script.
|
|
|
|
The framework contains a [test script](#test-the-new-source-file) that can be used to confirm source scripts are retrieving and returning correctly formatted waste collection schedules.
|
|
|
|
## Python Source Script
|
|
|
|
Create a new file in the `/custom_components/waste_collection_schedule/waste_collection_schedule/source` folder. The file name should be the url of your service provider in lower case, for example `abc_com.py` for `https://www.abc.com`.
|
|
|
|
The script should have the following general structure
|
|
|
|
```py
|
|
import datetime
|
|
from waste_collection_schedule import Collection
|
|
|
|
TITLE = "My Council" # Title will show up in README.md and info.md
|
|
DESCRIPTION = "Source script for abc.com" # Describe your source
|
|
URL = "https://abc.com" # Insert url to service homepage. URL will show up in README.md and info.md
|
|
TEST_CASES = { # Insert arguments for test cases to be used by test_sources.py script
|
|
"TestName1": {"arg1": 100, "arg2": "street"},
|
|
"TestName2": {"arg1": 200, "arg2": "road"},
|
|
"TestName3": {"arg1": 300, "arg2": "lane"}
|
|
}
|
|
|
|
API_URL = "https://abc.com/search/"
|
|
ICON_MAP = { # Optional: Dict of waste types and suitable mdi icons
|
|
"DOMESTIC": "mdi:trash-can",
|
|
"RECYCLE": "mdi:recycle",
|
|
"ORGANIC": "mdi:leaf",
|
|
}
|
|
|
|
|
|
class Source:
|
|
def __init__(self, arg1, arg2): # argX correspond to the args dict in the source configuration
|
|
self._arg1 = arg1
|
|
self._arg2 = arg2
|
|
|
|
def fetch(self):
|
|
|
|
# replace this comment with
|
|
# api calls or web scraping required
|
|
# to capture waste collection schedules
|
|
# and extract date and waste type details
|
|
|
|
entries = [] # List that holds collection schedule
|
|
|
|
entries.append(
|
|
Collection(
|
|
date = datetime.datetime(2020, 4, 11), # Collection date
|
|
t = "Waste Type", # Collection type
|
|
icon = ICON_MAP.get("Waste Type"), # Collection icon
|
|
)
|
|
)
|
|
|
|
return entries
|
|
```
|
|
|
|
Filtering of data for waste types or time periods is a functionality of the framework and should not be done by the source script. Therefore:
|
|
|
|
- A source script should return all data for all available waste types.
|
|
- A source script should **not** provide options to limit the returned waste types.
|
|
- A source script should return all data for the entire time period available (including past dates if they are returned).
|
|
- A source script should **not** provide a configuration option to limit the requested time frame.
|
|
|
|
## Service Provider Markdown File
|
|
|
|
Create a new markdown file in the `doc/source` folder. The file name should be the url of your service provider in lower case, for example `abc_com.md` for `https://www.abc.com`.
|
|
|
|
The markdown file should have the following general structure:
|
|
|
|
1. A description of how the source should be configured.
|
|
2. A description of the arguments required, the type, and whether they are optional/mandatory.
|
|
3. A working example (usually one of the test cases from the `.py` file)
|
|
|
|
For example:
|
|
|
|
**Configuration via configuration.yaml**
|
|
|
|
```yaml
|
|
waste_collection_schedule:
|
|
sources:
|
|
- name: abc_com
|
|
args:
|
|
uprn: UNIQUE_PROPERTY_REFERENCE_NUMBER
|
|
```
|
|
|
|
**Configuration Variables**
|
|
|
|
**uprn** _(string) (required)_ : The unique 12-digit identifier for your property
|
|
|
|
Example:
|
|
|
|
```yaml
|
|
waste_collection_schedule:
|
|
sources:
|
|
- name: abc_com
|
|
args:
|
|
uprn: "e3850cac2d5b"
|
|
```
|
|
|
|
Note: Your uprn can be found on invoices from your service provider
|
|
|
|
## Update Links in README.md and info.md
|
|
|
|
The `README.md` file in the top level folder contains a list of supported service providers.
|
|
|
|
The `info.md` is rendered in the HACS user interface within Home Assistant and gives potential users a summary of what the component does, and the service providers supported.
|
|
|
|
The links in both files can be updated automatically using the script `update_docu_links.py` in the top-level directory:
|
|
|
|
```bash
|
|
./update_docu_links.py
|
|
```
|
|
|
|
The script iterates through all source files and extracts some meta information like title and url. It is therefore important to set the attributes in the source file correctly. By default, the country classification is derived from the file name. If this doesn't match, the country code can be overwritten with the attribute `COUNTRY`.
|
|
|
|
| Attribute | Type | Description |
|
|
|-|-|-|
|
|
| TITLE | String | Title of the source. Used as link title in README.md and info.md. |
|
|
| URL | String | Service provider homepage URL. The idea is to help users to identify their service provider if they search for an URL instead of a service provider name. The abbreviated domain name is therefore displayed next to the source title in README.md. |
|
|
| COUNTRY | String | [Optional] Overwrite default country code which is derived from source file name. |
|
|
| EXTRA_INFO | List of Dicts or Callable | [Optional] Used to add extra links in README.md and info.md if the source supports multiple service providers at the same time. The following keys can be added to the dict: `title`, `url`, `country`. In case a key is missing, the corresponding value from the attributes above will be used instead. |
|
|
|
|
Examples:
|
|
|
|
```python
|
|
# Standard case: Source supports one service provider
|
|
TITLE = "ART Trier"
|
|
URL = "https://www.art-trier.de"
|
|
|
|
# Special case: Overwrite country code
|
|
TITLE = "RecycleSmart"
|
|
URL = "https://www.recyclesmart.com/"
|
|
COUNTRY = "au"
|
|
|
|
# Special case: Source supports multiple service provider which should be added to README.md and info.md
|
|
TITLE = "FCC Environment"
|
|
URL = "https://fccenvironment.co.uk"
|
|
EXTRA_INFO = [
|
|
{
|
|
"title": "Harborough District Council",
|
|
"url": "https://harborough.gov.uk"
|
|
},
|
|
{
|
|
"title": "South Hams District Council",
|
|
"url": "https://southhams.gov.uk/"
|
|
},
|
|
]
|
|
|
|
# Special case: Same as before, but EXTRA_INFO created by a function from existing data
|
|
TITLE = "Bürgerportal"
|
|
URL = "https://www.c-trace.de"
|
|
def EXTRA_INFO():
|
|
return [ { "title": s["title"], "url": s["url"] } for s in SERVICE_MAP ]
|
|
```
|
|
|
|
## Test the new Source File
|
|
|
|
Debugging a source script within Home Assistant is not recommended. Home Assistant's start-up process is too slow for fast debugging cycles. To help with debugging/troubleshooting, the Waste Collection Schedule framework contains a command line script that can be used to test source scripts. The script iterates through the `test cases` defined in the source script passing each set of arguments to the source script and prints the results.
|
|
|
|
The script supports the following options:
|
|
|
|
| Option | Argument | Description |
|
|
|--------|----------|-------------------------------------------------------------------------------------------------------------------------------------------------|
|
|
| `-s` | SOURCE | [Source name](https://github.com/mampfes/hacs_waste_collection_schedule#source-configuration-variables) (source file name without ending `.py`) |
|
|
| `-l` | - | List all found dates. |
|
|
| `-i` | - | Add icon name to output. Only effective together with `-l`. |
|
|
| `-t` | - | Show extended exception info and stack trace. |
|
|
|
|
For debugging purposes of a single source, it is recommended to use the `-s SOURCE` option. If used without any arguments provided, the script tests every script in the `/custom_components/waste_collection_schedule/waste_collection_schedule/source` folder and all yaml configurations in the folder `/doc/ics/yaml` and prints the number of found entries for every test case.
|
|
|
|
To use it:
|
|
|
|
1. Navigate to the `/custom_components/waste_collection_schedule/waste_collection_schedule/test/` directory
|
|
2. Confirm the `test_sources.py` script is present
|
|
3. Execute the test script. For example, testing the abfall_io.py source script would be:
|
|
|
|
```bash
|
|
test_sources.py -s abfall_io
|
|
```
|
|
|
|
4. Confirm the results returned match expectation. For example, testing abfall_io returns:
|
|
|
|
```text
|
|
Testing source abfall_io ...
|
|
found 285 entries for Waldenbuch
|
|
found 58 entries for Landshut
|
|
found 109 entries for Schoenmackers
|
|
found 3 entries for Freudenstadt
|
|
found 211 entries for Ludwigshafen am Rhein
|
|
found 119 entries for Traunstein
|
|
found 287 entries for Thalheim
|
|
```
|
|
|
|
5. To view individual date entries and assigned icons, use the `-i -l` arguments, for example:
|
|
|
|
```bash
|
|
test_sources.py -s richmondshire_gov_uk -i -l
|
|
Testing source richmondshire_gov_uk ...
|
|
found 53 entries for test 1
