Hi guys, im having some issues with cayenne and getting sensors going - this code (or very close to it) was going fine, then i changed some things unrelated to the onewire sensors and they’re just coming up with -127 degrees.
If i comment out the cayenne.begin part the serial monitor fills with the data i would expect.
Is there some stuff going on in the cayenne libraries that could stop this working? very confused, not a coder; strange to me that it was working then it just stopped.
Cheers

one thing i am however having trouble with - the cayenne app on ipad is not showing this board as online, its just grayed out - another board i have connected however is showing
