Can I daisy chain AHT20 sensors on the same Feather? Device component add codes:
Error: Key must be unique within the selected group
Error: Group feeds is invalid
I would really like to view multiple sensors on my dashboard.
Thank you for any help.

Yes. You can connect multiple AHT20 sensors to your ESP32. But most probably, the problem that you'll face is the same I2C address. This video will help you a bit in this matter: https://www.youtube.com/watch?v=wqyHbQvcoWw
