I have a Davis Vantage Pro that has worked flawlessly for many years with LWC and for the last few months with Weathercat 1.0.2.
Yesterday I upgraded to WC 1.1.3 without any apparent problem but now the basic external temperature and dew point graphs start at -30F (see attachment). The internal temperature basic graph does not have the problem. The computer is a Mac Mini Intel core2duo running 10.6.8
All readings and other graphs look reasonable and for the past 24 hours the data editor shows temperatures in the 45-70F region. No comms errors.
Switching between C and F still shows this big "zero" offset (-40C and -30F origin). I know I can set the initial max range for temperature but is there any way of setting the minimum?
If I create a custom graph of external temperature, it shows a scale with a reasonable range (40 to 80F).
Any ideas what could be wrong?
