Hello guys i have some problem with my IoT project, im not sure its a bug or my failure.
The problem is, when i write code for connected to cayenne platform at this part
“Cayenne.begin(username, password, clientID, ssid, wifiPassword);”
my sensor can’t read properly. but when i delete this code my sensor can read properly, can someone help me please :((
this is the full code from my project:

This is the fail sensor
And this is the good one
