Use AAT weather

[wtgee]

This gets most of the way there. I don't know which of the unknown_ columns are the actual safety readings, but I'm sure someone does.

Just need to add a safe: True/False value based off those columns.

import requests

url = 'http://aat-ops.anu.edu.au/met/metdata.dat'

columns = [
    'time',
    'ambient_temp',
    'dome_temp',
    'mirror_temp',
    'outside_dewpoint',
    'outside_humidity',    
    'pressure',
    'wind_speed_avg',
    'wind_gust_max',
    'wind_direction_avg',
    'unknown_3',
    'unknown_4',
    'unknown_5',
    'sky_ambient_diff_C',
    'sky_ambient_diff_error',    
    'boltwood_wetness_meter_maybe',
    'unknown_7',
    'unknown_8',
    'rain_since_9am',
    'sqm_brightness',
]

res = requests.get(url)
if res.ok:
    date, raw_data, _ = res.content.decode().split('\n')
    data = {name:value for name, value in zip(columns, raw_data.split('\t'))}
    data['date'] = date

which produces

{'time': '16:17:00',
 'ambient_temp': '7.9',
 'dome_temp': '5.9',
 'mirror_temp': '7.6',
 'outside_dewpoint': '-3.0',
 'outside_humidity': '46.2',
 'pressure': '667.1',
 'wind_speed_avg': ' 33',
 'wind_gust_max': ' 37',
 'wind_direction_avg': '180',
 'unknown_3': '0',
 'unknown_4': '0',
 'unknown_5': '0.6',
 'sky_ambient_diff_C': '-35.3',
 'sky_ambient_diff_error': '1.9',
 'boltwood_wetness_meter_maybe': '1858',
 'unknown_7': ' 0',
 'unknown_8': ' 0',
 'rain_since_9am': '0.0',
 'sqm_brightness': '0.00',
 'date': '" 05-27-2021."'}

For reference, here are the column names according to Steve Lee:

UT+10 i.e. local time, but NOT daylight saving time Out_T Outside temperature in degrees C In_T Inside dome temperature Mir_T Temperature of the AAT primary mirror (measured a few millimetres above the actual surface) Dew_O Dewpoint temperature of outside air Hum_O% Humidity of outside air Bar_mm Barometric pressure in mm of Mercury (for historical reasons) Wkph Measured average wind speed in kph WMax Maximum measured wind gust WDir Direction of wind in degrees (0=north, 90=east, etc.) D Flag for Dome state 0=Closed, 2=Venting, 4=Open R Flag for Rain 0=no rain, 1=Rain Dew_D Dewpoint temperature of dome air Sky-Amb Boltwood reported sky-ambient temperature +/-dev standard deviation of previous measurements Bright Boltwood reported sky brightness BR Boltwood rain sensor = number of times in 10 minute period rain detected BW Boltwood wetness sensor (as above) : values 0, 1...10; -1 no reading Rainfall Cumulative rainfall for day (reset at 9am local time).
