How can sync devices from my iOS Application to Apple Home

I am Switch Manufacturer,

I have an iOS application, where all switches can operate, it is light or fan now. I also have Alexa skill and Google Home Action where I operate devices through echo devices.

Now I need to develop and operate the device from Siri for that I need to sync devices from the Application to Apple Home.

Can you please guide how I can start? or which SDK I need to use for development?
