Hi Brian,
then with the last update, Weather Underground is updated every 5-10 minutes.
Different problem regarding WOW, CWOP, PWS
WOW: It updates strangely 1 time every hour, but also every 2 hours or 3 hours.
CWOP: It does not communicate data absolutely.
PWS: Same problem as WOW goes up every hour or sometimes every 2 hours or 3 hours.
