In my smartHUB settings, I managed to correct the station pressure to what other stations nearby are reporting. This was reflected on my dashboard. However, the one being shown in wunderground is still the uncorrected/ station pressure. How do I fix this?
At present there is no way to send a manual adjustment to wunderground. However, wunderground will eventually figure out you're sending station pressure and adjust it for you. How long that will take is an unknown, as wunderground isn't telling.
