@famished,

Im not too familiar with what type of setup you are looking at. From your description, it sounds like the power is first delivered to the bulb and then to the switch, I believe that this is relatively common in outdoor wiring. 

What is concerning is that if the switch is toggled off, at least as i understand these circuits there should be no electricity able to flow through the circuit, as it would be broken. I would ensure that your connections are correct and secure on the switch as it sort of sounds like you have a switch connected, that cant actually turn off the circuit. Is it actually a three-way with a hidden switch somewhere else?

Is it possible that the blinking and dimming are partly a result of the bulb beginning the configuration process and indicating that it is ready for setup in the app?

  @famished,

I cant really guarantee anything, but if I were to hazard a guess it would be that timer switch. it could be not providing consistent enough power for the main unit to read the light as on all the time. I would think that either bypassing the timer, or replacing it, you would be able to simplify the wiring setup and would be able to have a better idea of where the power is flowing from.

Also, keep in mind that you can create smart actions and timers in the Kasa app, so the timer wouldn't necessarily be needed unless it is also controlling another device.

 Hey @Elevate,

I would have recommended creating a new thread, as it would have been visible to more users.

What step in the setup are you having problems with the bulb connected to Wi-Fi?

What type of phone are you using to connect the bulb?

I would try to uninstall and reinstall the application, and also reset the bulb to factory defaults and see if the behavior persists.

What does the screen say is the issue with the process, and were you able to initially connect the bulb to the Wi-Fi
