I am new to creating CoRE pistons and need some help. I have a 3D printer that is connected to a IRIS Smart plug and is using @blebson DH that reads power. What I would like to do is turn the printer off after the print is finished. But rather than using a motion detector to trigger the plug as I have seen in other postings. I would like to have a piston that will shut off the printer after the wattage drops to below 3 watts for a 5 minute period of time. But I am struggling in finding where I can set up the duration variable. Is this possible?
