midas

Python ≥3.8 driver for Honeywell Midas gas detectors.

Installation

pip install midas

Usage

Command Line

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

$ midas 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.

```python import asyncio from midas 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:

python { 'alarm': 'none', # Can be 'none', 'low', or 'high' 'concentration': 0.0, # Current gas concentration reading 'connected': True, # Monitors heartbeat for connection 'fault': { # Fault data, when applicable 'code': 'F39', 'condition': 'User has generated a simulated fault.', 'description': 'Simulated fault', 'recovery': 'Reset simulated fault.', 'status': 'Instrument fault' }, 'flow': 514, # Flow rate, in cc / minute 'high-alarm threshold': 2.0, # Threshold concentration for high alarm trigger 'ip': '192.168.1.192', # IP address of connection, can be used to link to Honeywell's own web interface 'life': 538.95, # Days until cartridge replacement required 'low-alarm threshold': 1.0, # Threshold concentration for low alarm trigger 'state': 'Monitoring', # Can be any option in `gas_detector.monitoring_status_options` 'temperature': 26, # Detector temperature, in celsius 'units': 'ppm' # Units for concentration values }

Additionally, there are four commands which can be sent to the device * Clear all alarms and faults - detector.clear_alarms_and_faults() * Inhibit alarms - detector.inhibit_alarms() * Inhibit alarms and faults - detector.inhibit_alarms_and_faults() * Turn off inhibition - detector.remove_inhibit()
