($100 paid request) Serial/SafeString/Digital Read/Write bug is ruining my life

Sorry I should have explained I meant my #define s at the beginning which define the message "keys" that the safestring then gets compared to? From what I can tell these are still strings (double quote) and when I change them to single quote for char array I am getting a warning I am having trouble making sense of on the last parameter of the setRelay function

Those defines are c-strings (with a small s) not Strings so no problems there.
Now that your are using SafeStringStream with echo, you have freed up Serial to use for debugging.
Let me play with it here and get back to you.
