Hello, I installed the firmware sonoff_dimmer_DHT11_v2.5.3_p5.rar (https://github.com/SUPLA/ESP8266/tree/m ... off/v2.5.3)
connected the sensor, but I do not see the temperature (sensor working)

Are you sure you have connected the sensor correctly?
I have the impression, that the yellow wire is connected to the NC and not to the input S (data).

What kind of power you use?
If You use power supply from usb,try connect sonoff to 230v.

Hello...I had the same problem with module with DHT11 and red LED. One of resistance was 1kOhm instead 10kOhm. Please, check it carefully.Have a multimeter handy? Test your connections to and on the module.You should take a delay of 2 seconds between readings, - see datasheet.
I do not know how it behaves it readings are made too fast.
