The TP-LINK Smart Wi-Fi LED Bulb doesn't support Apple HomeKit but you can still use TP-LINK's Kasa App on the iPhone or iPad to set it up. We used the Apple iPad Pro to set up Kasa. In the Apple App Store, there wasn't an iPad version of the Kasa App so we had to download and install the iPhone version.
After opening the Kasa App, we had to create a Kasa account to log in.
After selecting the '+' button at the top right of the Home screen, we can select Smart Bulb.
We then had to connect the TP-LINK Smart Wi-Fi LED Bulb to a powered light socket and after it blinked three times, the TP-LINK Smart Wi-Fi LED Bulb starts to temporarily act as a Wi-Fi router. Unlike Android phones and tablets, you need to manually connect the Apple iPad Pro to the Wi-Fi network set up by the TP-LINK Smart Wi-Fi LED Bulb.
Once the Apple iPad Pro joined the TP-LINK Smart Wi-Fi LED Bulb's Wi-Fi network, we could then set up the local Wi-Fi network for the TP-LINK Smart Wi-Fi LED Bulb to join.
Once the setup process was completed, we could see the TP-LINK Smart Wi-Fi LED Bulb in the Kasa App, control the light color and intensity, as well as monitor the energy usage.
If you select the three horizontal lines on the top left of the Kasa App, you can see the App's menu items and open the Device Settings which is where you can delete the device if needed.
Though the menu, you can also select Alexa Integration which are just links to help screens.
You can also use the Kasa App to update the firmware on the TP-LINK Smart Wi-Fi LED Bulb. After a few tries, we were able to successfully update the firmware.
Unfortunately, we found that the TP-LINK Smart Wi-Fi LED Bulb often lost network connection and we were unable to connect to it using the Apple iPad Pro.
Also, even though you can run the Kasa App on the Apple iPhone and iPad products, the TP-LINK Smart Wi-Fi LED Bulb doesn't support Apple HomeKit so you can't add or view it through the Apple Home App.
