pyhearth 1.1.0

pyhearth is a Python client for Hearth's home API. It posts thermostate and/or room sensor readings to a Hearth home with the home's API key, and returns the thermostat setting Hearth answers with. It's what ha-hearth, Hearth's Home Assistant integration, uses to talk to Hearth.

Installation

pyhearth is available on PyPI and can be installed using pip:

pip install pyhearth

Basic Usage

In the Hearth app, create the home's API key in Settings, then Manage home, then Sensors, then "Other sensors (Hearth API)". Then post readings:

import asyncio

import aiohttp

from pyhearth.client import HearthClient


async def main():
    async with aiohttp.ClientSession() as session:
        client = HearthClient(session, "<your API key>", source="my-hub", source_name="My hub")
        result = await client.post_readings([
            {"id": "office", "name": "Office", "temperature": 20.8, "humidity": 41}
        ])
        print(result.not_added)


asyncio.run(main())

A sensor's readings are kept once it's added to a room in the Hearth app; until then, it's listed in not_added. The fields each endpoint takes are in Hearth's API docs.

Errors are raised as subclasses of HearthError (in pyhearth.exception): HearthAuthError when Hearth doesn't take the key, HearthRateLimitedError when it asks for fewer posts (meta["retry_after"] says how many seconds to wait), HearthRejectedError when it can't read a post, and HearthConnectionError when it can't be reached.
