Thanks
Do you know of anyway to remove the extra decimal places?
I'm using a DHT11 and the data for temp shows two decimal places but only one is used. ie: 22.2 For humidity two decimal places but only whole number.

I am using heltec + ds3231 and I have a problem.

I connect the pin SCL, SDA of ds3231 to pin 22, 21 of the heltec.


I think if running a command related to OLED, the time from RTC displayed at Serial Monitor will not be correct.

Do you have any advice? Thank you.
