OK thanks miralant.
problem is that the temp value is 15 degrees celcius above the real temp.
Thats a big difference between the +/- 2 degrees they should differ.
Did you just replace the DHT11 on the board and reuse the board where the ESP-01 is put on?

Hi,

I've the same issue, high vaules of both temperature and humidity.
Also the output is changing, but not as you would expect.
Did someone solve this?
