@blazoncek i just remembered. Am I not right in thinking the settings instance is not needed as a separate field? To update it, I have to use setSettings() which means a copy is made in the bme instance. So having a copy of the settings in this class is just double the data. So I can remove the field with settings and create the settings every time I need it instead. Yes? :) |

According to the library documentation that may be sufficient. |

Seems to work as well. |

The BME280 usermod assumes an address of 0x76 which is incorrect for the BMP280 chip, which defaults to 0x77. This change puts the i2c address into the config and defaults to 0x76.
Notes:
This builds on Fix missing conversions of bme280 values #3965. I'll rebase when that's merged.As of right now, WLED must be rebooted for the address change to take effect. I'm not much of a C++ developer to know the ins and outs of reinitializing theBME280I2Cinstance .. do I stop it? delete it? .. If that was fixed, rebooting wasn't necessary.New config view. The
I2CAddressis new - here set to 0x77.
