spmflex

Python ≥3.5 driver for Honeywell SPM Flex gas detectors.

Installation

pip install spmflex

Usage

Command Line

To test your connection and stream real-time data, use the command-line interface. You can read the state with:

$ spmflex 192.168.1.100

This will output a JSON object which can be further manipulated. See below for object structure.

Python

For more complex behavior, you can write a python script. This solely uses Python ≥3.5's async/await syntax.

import asyncio
from spmflex import GasDetector

async def get():
    async with GasDetector('192.168.1.100') as detector:
        print(await detector.get())

asyncio.run(get())

If the detector is operating at that address, this should output a dictionary of the form:

{
    "concentration": 0.0,
    "connected": true,
    "fault": "No fault",
    "flow": 256,
    "gas": "AsH3 - Arsine",
    "high-alarm threshold": "5.0",
    "id": "SPMFLEX08000000",
    "ip": "http://192.168.1.100/",
    "life": 93.0,
    "low-alarm threshold": "2.5",
    "temperature": 0,
    "units": "ppb"
}

This is a cleaned-up version of the data returned. If you want to see all of it, set raw=True.
