I am having a really hard time with a project. I want to have two sensors, the CCS811 and the BME680 on the same I2C bus. I am using a ESP82. When I dont have the BME connected, the CCS811 works fine, when I plug in the BME680 the humidity and temperature of the CCS811 are way off, sometimes negative. From the information each of these sensors have a different default I2C address, so that shouldn't be the problem. Has anyone tried to use the CCS811 and the BME680 at the same time? I would like to compare readings between the two sensors.
