Python: Twente Milieu

Asynchronous Python client for the Twente Milieu API.

About

This package allows you to request waste pickup days from Twente Milieu programmatically. It is mainly created to allow third-party programs to use or respond to this data.

An excellent example of this might be Home Assistant, which allows you to write automations, e.g., play a Google Home announcement in the morning when it is trash pickup day.

Installation

pip install twentemilieu

Usage

import asyncio

from twentemilieu import TwenteMilieu, WasteType


async def main() -> None:
    """Show example on stats from Twente Milieu."""
    async with TwenteMilieu(post_code="1234AB", house_number=1) as twente:
        unique_id = await twente.unique_id()
        print("Unique Address ID:", unique_id)
        pickups = await twente.update()
        print("Next pickup for Non-recyclable:", pickups.get(WasteType.NON_RECYCLABLE))


if __name__ == "__main__":
    asyncio.run(main())

Behavior & error handling

Each API call is a single HTTP POST — the client does not retry on transient failures. If you need retries with backoff, wrap the calls in your own retry loop (or use something like backoff).

Requests are bounded by a per-call timeout, which defaults to 10 seconds and can be overridden via the request_timeout constructor argument:

async with TwenteMilieu(
    post_code="1234AB",
    house_number=1,
    request_timeout=5,
) as twente:
    ...

Cancellation is plain asyncio: cancelling the task awaiting unique_id() or update() aborts the in-flight request, and the context manager still cleans up the internal session on exit.

All exceptions inherit from TwenteMilieuError:

Command-line interface

This package ships with an optional CLI that is handy for quickly inspecting the waste pickup schedule for an address. Install it with the cli extra:

pip install "twentemilieu[cli]"

The CLI exposes two commands: upcoming (a chronologically sorted list of the next pickups across all waste types) and next (the single next pickup, optionally filtered by waste type). Both commands accept --post-code, --house-number, and an optional --house-letter, and both support a --json flag for machine-readable output.

# Show the next 5 pickups across all waste types
twentemilieu upcoming --post-code 7531AT --house-number 148

# Limit to the next 3 pickups and emit JSON
twentemilieu upcoming --post-code 7531AT --house-number 148 --limit 3 --json

# Show the very next pickup (any waste type)
twentemilieu next --post-code 7531AT --house-number 148

# Show the next organic pickup only
twentemilieu next --post-code 7531AT --house-number 148 --waste-type organic

# Emit as JSON for use in scripts
twentemilieu next --post-code 7531AT --house-number 148 --waste-type organic --json

Address options can also be supplied via the TWENTEMILIEU_POST_CODE, TWENTEMILIEU_HOUSE_NUMBER, and TWENTEMILIEU_HOUSE_LETTER environment variables. Run any command with --help for the full reference.

Changelog & Releases

This repository keeps a change log using GitHub's releases functionality. The format of the log is based on Keep a Changelog.

Releases are based on Semantic Versioning, and use the format of MAJOR.MINOR.PATCH. In a nutshell, the version will be incremented based on the following:

• MAJOR: Incompatible or major changes.
• MINOR: Backwards-compatible new features and enhancements.
• PATCH: Backwards-compatible bugfixes and package updates.

Contributing

This is an active open-source project. We are always open to people who want to use the code or contribute to it.

Setting up development environment

The easiest way to start, is by opening a CodeSpace here on GitHub, or by using the Dev Container feature of Visual Studio Code.

This Python project is fully managed using the Poetry dependency manager. But also relies on the use of NodeJS for certain checks during development.

You need at least:

• Python 3.11+
• Poetry
• NodeJS 24+ (including NPM)

To install all packages, including all development requirements:

npm install
poetry install

As this repository uses the prek framework, all changes are linted and tested with each commit. You can run all checks and tests manually, using the following command:

poetry run prek run --all-files

To run just the Python tests:

poetry run pytest
