AdafruitIO_RequestError

[mweisbr]

Hello there,

I have a problem with adafruitIO. With the following code i get an error message.

AdafruitIO_RequestError: Adafruit IO Error 400: ['Name must be unique within the selected group', 'Key must be unique within the selected group', 'Name must not match an existing key within the selected group', 'Group feeds is invalid']

Unfortunately I have no idea what I am doing wrong. If I comment out the three carbonfeed lines, then it works.

Thanks for your help!

Hello,

What sensor board are you using? Is it the AHT20 board?

Hello,
I'am using two different sensors: EZO Co2 Atlas Scientific and AHT20 for Temperature and Humidity. if i comment out all lines with the aht20 feed the code works and co2 data is sent to IO. If I comment out the lines with the co2 sensor feeds, temperature and humidity are sent to IO. Only if all are activated the error message appears.
