No pressure for tomorrow morning then.....(grin)! If you ever want a sample of one of my flows, they are easy to download and the upload into another Node-Red machine. I use this process to backup my flows and I recently changed out my mqtt mosquitto broker from a Pi 3 to Pi 2 because I only use a wired connection for my broker for higher reliability and didn't want to waste the Pi3 when the Pi2 is more than enough. So I downloaded the flow from the Pi3 and uploaded it into the Pi2, very slick!
