Python driver for Honeywell SPM Flex gas dectectors.
Project description
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
.
