p1monitor 3.0.1

Asynchronous Python client for the P1 Monitor

Asynchronous Python client for the P1 Monitor API.

About

There are many ways to read the serial port (P1) of your smart meter and what you do with the data that comes out. With this python library your platform can read P1 Monitor via the API and use the data for example for an integration in Home Assistant.

Installation

pip install p1monitor

Usage

import asyncio

from p1monitor import P1Monitor


async def main():
    """Show example on getting P1 Monitor data."""
    async with P1Monitor(host="example_host") as client:
        smartmeter = await client.smartmeter()
        watermeter = await client.watermeter()
        settings = await client.settings()
        phases = await client.phases()
        print(smartmeter)
        print(watermeter)
        print(settings)
        print(phases)


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

Data

There is a lot of data that you can read via the API:

SmartMeter

• Gas Consumption
• Power Consumption / Production
• Energy Consumption Low/High
• Energy Production Low/High
• Energy Tariff Period

Phases

• Voltage phases L1/2/3
• Current Phases L1/2/3
• Power consumed phases L1/2/3
• Power Produced phases L1/2/3

WaterMeter

[!IMPORTANT] WaterMeter is only available when you run version 1.1.0 or higher due the use of the new v2 API url.

• Day Consumption (liters)
• Total Consumption (m3)
• Day Pulse count

Settings

• Gas Consumption Price
• Energy Consumption Price Low/High
• Energy Production Price Low/High

Contributing

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

We've set up a separate document for our contribution guidelines.

Thank you for being involved! :heart_eyes:

Setting up development environment

The simplest way to begin is by utilizing the Dev Container feature of Visual Studio Code or by opening a CodeSpace directly on GitHub. By clicking the button below you immediately start a Dev Container in Visual Studio Code.

This Python project relies on Poetry as its dependency manager, providing comprehensive management and control over project dependencies.

You need at least:

• Python 3.11+
• Poetry

Install all packages, including all development requirements:

poetry install

Poetry creates by default an virtual environment where it installs all necessary pip packages, to enter or exit the venv run the following commands:

poetry shell
exit

Setup the pre-commit check, you must run this inside the virtual environment:

pre-commit install

Now you're all set to get started!

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

poetry run pre-commit run --all-files

To run just the Python tests:

poetry run pytest
