Hello,
So I’m using the AM2315C sensor as the AM2315 has been discontinued.
Am I able to change the i2c address of the AM2315 input that’s pre-configured or do I need to add a custom input for my AM2315C sensor?
Mine is greyed out so not sure if and where I can change it?
AM2315 i2c address = 0x5C
and mine, AM2315C i2c address = 0x38
After some research I figured out that the new AM2315C sensor is actually the AHT20 sensor on the inside. Ref: AM2315C - Encased I2C Temperature/Humidity Sensor (Adafru... | Little Bird
So I removed the AM2315 input and added the AHTx0 Input which is correct as the i2c address shows as 0x38
But I’m still not able to get any data from it 
Below are my logs:

Does this mean there is a wiring issue?
This was resolved by rewiring the Temp sensor, guess it didn’t take the first time
