Barometer Calibration for Altitude
Use this link for altitude offsets. This setting will be available after v1.3.1

I2C addresses of sensors I have
These are my sensors and they work with the addresses in the Arduino code. I strongly recommend running a port scan to make sure your devices are responding in the same manner. Driver.begin() functions can usually be modified for alternate addresses from different vendors.
Accessory | I2C address | Comments |
|---|---|---|
UV - SI1145 | 0x60 | UV sensor |
Lux - BH1750 | 0x23 | light level sensor |
Barometer/ Relative Humidity - BME280 | 0x76 |
|
EEPROM | 0x50 | Extended reliability for rainfall collection. Not as interesting now that we fail WiFi connect more gracefully in v1.3.1 (without tripping WDT) |
