Upload the code everything works fine but after about 25-30 minutes the indoor temp and humidity shows:

Answer 1

I had the same issue to start with, did you enter your Chanel number and "READ" key from Thingspeak?

If not that is why you are getting a NULL reply.

Hi,
I meant the part of the program that measures the temp and humidity from DHT11and display it directly to the OLED, not through Thingspeak.
