Autonomo + DHT11 on GROVE

Hi guys,
I’m trying to use this grove board with a DHT11 but seems there no way to receive value from the sensor.
I tried different libraries:

    Here I have an error in debug mode “timeout waiting for start signal low pulse”

    This should be incompatible with 48Mhz, but I tried to modify the COUNT definitiopn in DHT.h,but in any case I have a zero value read from sensor.

There is another library you can find, according to the Seed website:
But this one is probably incompatible with Autonomo

The test code is very simple, something similar to this example
with the sensor connected to the Autonomo Grove Shield port A0

Could you please tell me what you think about the first two libraries?
