New Tapo plug P110 is paired, showing on app, performing actions on app to turn lights on and off but plug is not turning lights on. Nothing wrong with lamp, tried other appliances and sockets. 
Two   other  older Tapo plugs P100 have gone offline and I can't get them to work. This was the reason fir purchasing new plugs. WiFi is fine, no issues. It's not the house or electrical issues. Anyone on here who can help?
