Thank you! I had exactly the same problem and your code has fixed it. Now I'm very tempted to dig and find out why Adafruit's code didn't - it would be nice to give something back for a change, cos I bet the same fix would work for BMP180 and 280.
So glad to see even one of these sensors working on the ESP.

@reaper7 your code works but the altitude is always 149.99m
I 've found this

it's true, because in example for calculate altitude as parameter is given RELATIVEPRESSURE (calculated from defined my home alt ~150), so...simply replace parameter from relativepressure to realpressure

I have had exactly the same output with the bme280 and the nodemcu-12e. I have concluded that it is not worth the trouble until someone comes along with a library that actually works. I have had no difficulties with other sensors, including the bmp180.
