Why does the Wi-Fi Connection Fail?

Can this smart bulb be used with any Dimmer Switch?
No, it is not designed to be used with dimmers. It can only be dimmed via the App. The bulb may flicker or behave unpredictably if used with a dimmer.
Can this smart bulb support Apple HomeKit and be controlled via Siri？
This smart bulb does not support Apple HomeKit. But it can be controlled by the one-tap operation via Siri.
