I have a 5 and 1 sensor and the Smart Hub. I connect the setup to Weather Bug PWS. My display vs what I report are about 5 in HG off! The display is within .1-.2 of other apps by my hub reports -5” to Weatherbug. Does the Smart Hub sense barometric pressure or does it get the info from the sensor ? Why is it off so much? It’s been doing this for months.
