I have recently ordered multiple beginner kits for my school. The temp and humidity sensor is upgraded to a DHT22 rather than 11. I have been able to get the code on but the readings on the OLED are ‘nan’. Could someone advise? Thanks,

Same problem here and also a teacher.
My board is showing an I2C connection rather than the D3 documented everywhere else.
I think there was a version update that changed the temp sensor but i dont know of any changes to the lotus part… what problem are you having?
The example code uses digital pin 3.
The sensor is labeled as I2C on my version of the board.
I’m not sure how to make the changes in the program yet.
The new kit change to be an I2C DHT20. we have the code to use the DHT20 put up on the Wiki. Can have a look.
