Communication with AHT10 failed!

variant: AHT20 # Specify the model as AHT20

Silly thing to miss - Thanks mataksik - took me 5 AHT20 BMP20 cards to discover they were all good :slight_smile:

this one solved my problem. thank you very much

also double checked and it is an aht10 but only works when you set variant to aht20
