To protect your equipment from the environment, SkyRoof utilizes a standard 'Boltwood II' one-line weather file to monitor the weather.

 The weather file, which is generated by a cloud sensor system, contains pertinent data of the prevailing weather conditions.


Below is an example of a typical one-line weather data file:


2018-01-17 14:51:45.00 F M 35.9   78.1  78      0      45  56.1   000 0 0 00020 043117.61927 1 1 1 3 0 0


Each weather data entry is separated by one or more spaces.



From left to right, values are:


  • File write date
  • File write time
  • Temperature scale (Celsius or Fahrenheit)
  • Wind speed scale (Mph or Knots)
  • Sky Temperature
  • Ambient Temperature
  • Sensor Temperature
  • Wind Speed
  • Humidity
  • Dew Point
  • Dew Heater Percentage 
  • Rain Flag
  • Wet Flag
  • Elapsed time since last file write
  • Elapsed days since last write
  • Cloud/Clear flag (1=Clear,2=Light Clouds,3=Very Cloudy)
  • Wind Limit flag (1=Calm,2=Windy,3=Very Windy)
  • Rain flag (1=Dry,2=Damp,3=Rain)
  • Darkness flag (1=Dark,2=Dim,3=Daylight)
  • Roof Close flag
  • Alert flag (0=No Alert,1=Alert)


Whenever SkyRoof is running and connected to a data file, the data file is read every ten seconds and the program logic determines

if the values are 'Safe' or 'Unsafe'. In turn, SkyRoof will either close or open the roof depending on the user's settings.


SkyRoof can also read and parse the older "Boltwood I" format weather files although the format is generally deprecated and not recommended.

In this case, some of the Weather Condition fields will not be populated and Action/Alert settings will be limited.
