Factory reset your Smart Plug

Note: When you factory reset the plug, any Automations, rules, Scenes or the SmartThings Button associated with the plug will need to be reset.

If your SmartThings Smart Plug is acting funny, a simple factory reset usually fixes the problem. It's one of the easiest and most effective ways to resolve any software issues that plug may be having.

With just a couple steps, your SmartThings Smart Plug will be problem-free. Before resetting the Plug, you should remove it from the SmartThings app.

To do a factory reset, press the Power button on the plug for five seconds. The LED on the front of the plug will blink red. This indicates that the plug is resetting. When the LED slowly blinks green, the reset is complete. Then, add the Smart Plug back to the SmartThings app.
