What's the model number ? Are you able to control via kasa app locally and remotely?

1.7.1 is the newest firmware. Did you hard reset the bulb? When it went down, does it show offline or something? BTW, the bulb stops working means you cannot control it even when you are on the same...

If you bought it in the US, the lamp base should be E26, 100V-120V. I don't think you can use in the Philippines.

That can not be disabled. It will light up automatically when the light is off, so you can find the switch in the dark.

Your tpcamera is updated? Reset the cam, try again. Or configure it via computer then manage it on your phone

Access the cam admin interface. Go to Advanced > Video, there is "Time Stamp&On-Screen Display (OSD)" option, enable it. https://www.tp-link.com/en/faq-817.html
