Support for BMP280 about esphome HOT 6 CLOSED

I will have a look at it. Doesn't seem too different from the BMP180 and BME280, so integrating it should not be that hard for me :)

from esphome.

I bought a bunch of these sensors a while back before I found the HTU21D. For temperature-only things are BMP280 still useful, don't care much about the pressure 😉.

Well, if I'm the only user then it doesn't make sense to integrate it.

I tried to use the BME280 and make a BMP280 out of it. Only partial success, readings are off because it seems that I'm not able to initialize the sensor properly.

I have a GY-21P Breakout which I understand is a BMP280 combined with SI7021 for temperature and humdity (although honestly I only care about temperature).
It would be great to be able to use this with esphomeyaml.

hi guys. Im trying to work with 02 bmp280 sensors, but only one has working. im using spi protocol. someone can help me?? im studying arduino, very unprofessional. I already tested the two sensors individually. are working perfectly.
