Hello @prabhakarmohan
Thank you for reaching out to us.
Please make sure you've run some basic troubleshooting steps if the plug does not cut off power to the home appliances
- Try a different device connected to Tapo plug
- Factory reset plug: How to factory reset the Tapo smart plug
- Try manually push the power button on the Plug itself and see if it can provide or cut off power to the home appliance.
If still the same , it could be a faulty unit. You could contact retailer or local support to check device warranty. When reach the support, please help provide the model of the device and its wattage, e.g. Bed Lamp 15W & note if the issue occur safter a thunderstorm or power outage?
Hope this helps
