When I try to compile the temperature module, I keep getting Losant.h: No such file or directory  
Does anyone have the header file or a location for it?

Thanks

What version of Arduino IDE are you using?

Is the library correctly installed? You should see it in Documents/Arduino/libraries/losant-sdk-arduino.

I found out the issue, I had to install it separately. Found the link on losant website.
