altruistclient 0.1.1

Async library for discovering and fetching data from Altruist sensors

AltruistClient

Python async library for discovering and communicating with Altruist ESP32-based sensors over the local network using mDNS (zeroconf) and HTTP.

Features

• Discover sensors on your LAN using Zeroconf (_altruist._tcp.local.)
• Fetch sensor metadata and measurement data from /data.json
• Filter supported sensor names
• Async/AIOHTTP-based for fast, non-blocking usage

---

Installation

pip install atruistclient

---

Quick Start

import asyncio
from aiohttp import ClientSession
from zeroconf.asyncio import AsyncZeroconf
from altruistclient import AltruistDiscoverer, AltruistClient

async def main():
    async with AsyncZeroconf() as zc, ClientSession() as session:
        discoverer = AltruistDiscoverer(zc, session)
        devices = await discoverer.get_devices()

        for device in devices:
            client = AltruistClient(session, device)
            data = await client.fetch_data()
            print(f"Device {client.device_id} (fw: {client.fw_version})")
            print("Sensor names:", client.sensor_names)
            print("Data:", data)

asyncio.run(main())

Class Overview

AltruistDiscoverer

• Scans for _altruist._tcp.local. devices using zeroconf.
• Filters and validates devices via their /data.json response.
• Returns a list of AltruistDeviceModel instances.

discoverer = AltruistDiscoverer(zc, session)
devices = await discoverer.get_devices()

---

AltruistClient

• Handles data fetching and parsing from a specific device.
• Extracts firmware version, sensor types, and measurements.

client = AltruistClient(session, device)
data = await client.fetch_data()
print(client.fw_version, client.sensor_names)

You can also construct it directly from an IP:

client = await AltruistClient.from_ip_address(session, "192.168.1.45")

---

AltruistDeviceModel

Simple dataclass containing:

• id: sensor ID (from /data.json)
• ip_address: resolved IP
• fw_version: firmware version (optional)

@dataclass
class AltruistDeviceModel:
    id: str
    ip_address: str
    name: str = "Altruist Sensor"
    fw_version: str | None = None

---

Notes

• get_devices() waits 5 seconds for mDNS discovery.
• Only devices that respond to /data.json and provide a valid sensor_id are returned.
• Internally uses aiohttp.
