On my Acurite Access Info page the pressure is reading 28.35 as in the pic. On my display it’s reading 29.72. Can someone explain to me the huge difference between the two. Also is there away to correct it so they are the same reading?
The first thing to know is that there are two individual sensors involved here. One in your display and one in the Access hub, each with their own offset errors. Assuming you bought a bundle with a 5n1, the barometric data does not come from there.
Second, the display will auto calibrate over time. Excellent discussion here:
