Brian is very willing to support users, but since you have 100% control of the file format IMHO it would be better to use one of the existing file formats that are already coded in WD than have him re-invent yet another wheel. For a simple dataset like that there is the “universal” file functionality. The format is in the universal.txt file in the Windows version, I’m not sure if it exists in linux (yet) but it is long established in Windows.
Description of the universal file input weather station type
Create a file with the following format, called datain38.ini (just 1 line of current data)
6.02 8.77 16.1 38 1010.2 0.0 215 15.8 21.5 58 200
i.e
6.02 Gust (current) speed (kts)
8.77 wind speed (kts)
16.1 Temperature (oC)
38 Humidity
1010.2 Barometer (hPa)
0.0 Daily rain
215 Wind direction
15.8 Soil temperature
21.5 indoor temperature (oC)
58 Indoor humidity
200 solar (WM/2)
Anyway, I’ll butt out now and let Brian take this
