I have made the layout in Blynk app. have the email with the token. SHH to my raspberry pi in Terminal on my Mac. Type in :

export PATH=$PATH:/opt/nodejs/bin/
unset NODE_PATH

The everything works just fine. Until I turn off my computer of close Terminal. Is there a way I can have Blynk run it for me to take my laptop out of the equation?
