    @DavidS - Very good, I had not seen the diurnal pressure change. Thanks for sharing. @Stan The old barometers had a sun for rising barometer because fair weather (high) was coming in and clouds for falling pressure (low) coming in. Altitude on the BME280.h is adjusted by a define ; Altitude Adjustment = 1.2 hPa * altitude in Meters *10 ; Altitude Adjustment = 1.2 hPa * altitude in Meters *10 #define BME280_AltitudeAdjustment 3240 ' 3240 for my 270 meters altitude This is a rule of thumb but the real...

    Changed Temperature to integer and temperature below 32F works now. Pressure works - it has to stay long Humidity works Rearranged and cleaned developement code out. Should write some "help" file for it. There are comments. Stuff to do yet. Here are the current files.

    With the help of Theo and Thomas Henry we got them both to work, BMP180 and BME280. Humidity was not working on the BME280 but i think it is fixed. In testing mode right now. Here is the latest BME 280 files 73 Mike

    The good news is that I got 4+ additional inches of snow and the barometer dropped from 30.23 to 29.92. That wasn't the good news, I have to shovel and plow. The good news was the BME280 tracked down and agrees with the barometer. @Anobium Note in the data you sent yesterday, the humidity should have gone up a lot when the temperature went down. Further checking of equations and types. Altitude: Yes Bosch published a fun 5.255 power equation but below that in the BMP180 sheet the give a rule of thumb,...

    @Theo Thanks again for the code. There were a couple of problems in the 32bit signed routines. i think i fixed. They work for me. Please try the attached and let me know if it works 73 BR Mike w9ys

    I think these are the 32 bit signed routines that you refered me to a while back but i never found. I want to try them out. And this is yet another pressure chip BMP 180 that I don't have one of. So please don't wait for me. 73 Mike
