WeatherCat version 1.1.1 and later offers support for the Fine Offset WH1080/2080 range of stations. WeatherCat version 1.1.4 adds support for WH3080 stations (solar/U.V.). These are USB based stations and do not require a USB to serial converter or driver.

To use one of these stations with WeatherCat, please select either the WH1080 station driver (for 1080/2080's) or the WH3080 station driver in the communications setup window.

Notes: It is currently not possible for WeatherCat to distinguish between these stations (they all use the same U.S.B. I.D.'s) - if you select the wrong driver the data will not be extracted properly from the data logger. Secondly, if your station did not come with a ferrite clamp on the USB cable, do install one - this can help prevent the console locking up.


These stations are sold under various brand names and part numbers. Some examples include: Ambient Weather WS-1080, WS-1090, WS-2080, Maplin N96GY/FY, Clas Ohlson (36-3242), Watson W-8681, Watson W-8681-SOLAR, Velleman WS 1080, Digitech XC0348, Aercus WS3083, and ClimeMet 2000.

Troubleshooting tips

Weather Station no longer is detected by WeatherCat or the Macintosh
Try resetting the station by powering off your console for 10 minutes, then powering it back up, and setting the date/time on the console once more.
WeatherCat restarts itself during the process of downloading data from the console data logger
If the data download takes too long, it can appear that WeatherCat is hung and cause the watchdog process to restart WeatherCat. You will need to switch off the watchdog process by launching WeatherCat, then quickly disable the watchdog process before it starts to download. To do this, open its preferences and select the 'Units/Misc1' pane. Down the bottom you'll see the option 'Monitor & Relaunch WeatherCat' - turn this off.
