NOTE: If you are using the AirQuality Extender and the Solar Power Extender in the same OurWeather setup then you need to make a change to the ADC included in the AirQuality Extender Kit. Do the following:
If you have the Solar Power Extender Kit and the Air Quality Extender, you have a conflict in the I2C addresses being used by the Air Quality Extnder.
The SAP (SunAirPlus) ADS1015 has a non-changable address of 0x48
The WeatherPlus board ADS1115 has a non-changable address of 0x49 (this is for the weather vane)
The Grove ADC1115 in the Air Quality kit has a default address of 0x48, which conflicts with the SAP board.
---To Solve!---
Solder a pin to the pinhole marked ADDR on the Grove ADS1115 board and then connect a jumper from ADDR to SDA (in the pin header row on the same board), power it back on and then the board now has the I2C address 0x4A
Then, in the OurWeather Software, in SDL_ESP8266_WeatherPlus.ino (the main file) change the following line:
Adafruit_ADS1115 adsAirQuality(0x48);
to
Adafruit_ADS1115 adsAirQuality(0x4A);
All devices will then work.
