I wanted to use the smart plug to restart my Nest mesh router. I set up an automation in Google Home to turn off the router, wait 20 seconds, and then turn it back on. My understanding was that the smart plug did not need the WiFi to be active as the schedule would be processed by the plug. However, my automation will turn off the router but will not turn it back on. I have set a fixed IP address for the smart plug. Does the smart plug require WiFi to be active to make this approach work?
