KP405 - Just turns off and on arbitrarily
KP405 is controlling LED Outdoor Patio lighting. About 30 feet from the WiFi router on the other side of a brick wall. Up until tonight no issue but this evening the light will just power off and then power on arbitrarily. Checked the KasaSmart app on my iPhone. When the lights are out the apps show the plug still on. I can press the power icon on the app and the lights will power on. This has happened several times this evening that we ended up just removing the smart plug and connecting the LED lights directly to the AC plug. No issues with the lights/plug so that rule out the LED lights or the power outlet.
This setup has been in place probably for the last 9 months so the plug has endured the harsh Texas summer and mild winter temperatures.
What is the next step to correct this device?
