Just curious: how are you using the DHT22? Would you please send some code example?
it working correctly . if you use DHT11 you need resistor 10k and also Diode . If you use DHT22 you need 74hc125 and resistor 10k .
for code i use code from example in library . i cant share it over here because too long ( over 400++ lines)
Thank you very much,

How are you connecting your board to the relay module? Could you please send us a schematic of how you would connect the two? And if possible share with us a picture of the physical connection of both boards.
You mention that the relay module is powered separately from the Galileo, so, I suspect that maybe the circuit might not be properly connected.
