I have a Shelly Plug S and I can turn it on or off from my dashboard. However, I am controlling a laser printer with it and I’ve heard that is is not good for laser printers to get turned on or off to fast. (they have to warm up.) How can you limit a switch so it can only switch state every 15 minutes. So I’ve turned on my printer I have to wait 15 minutes before I can turn it of.
