Setup guide
- Download Tuya Smart or Smart Life and create an account.
- Plug the LP405 into a socket. The display lights up and the Wi-Fi indicator blinks.
- In the app tap Add device → Auto scan, or choose the socket category manually.
- Enter your 2.4 GHz Wi-Fi password. The LP405 does not support 5 GHz networks.
- Rename the device and, if you want cost tracking, set your three tariff rates.

Troubleshooting
The plug will not connect to Wi-Fi
Use a 2.4 GHz network, keep the phone within two metres during pairing, and make sure the router is not using WPA3-only or a captive-portal guest network.
The relay clicks but nothing switches off
Check that the appliance is not drawing more than 25 A. The overload trip disconnects the load and shows a protection code on the display; it re-arms automatically once the load is removed.
Readings stay at zero
Metering starts only after the relay closes and a load is present. Verify the appliance is actually switched on.
The display is blank
The plug draws its own supply from the mains. If the display stays dark with the outlet live, contact support — do not open the housing.
History is missing after a power cut
Cloud history needs Wi-Fi; the SD card keeps a local log. Reconnect and let the app sync.
