HomeKit integration for a Bluetooth lighting system from Koizuni . The KOIZUMI lighting system supports Google and Amazon , but not Apple HomeKit .

I'm looking to integrate the KOIZUMI lighting system with Apple HomeKit for On/Off control. I'd like to be able to control this system with voice commands through Siri, and I don't have any other devices that need to be linked to the lighting system. This project requires the integration of the system with Apple HomeKit, and I'm looking for a freelancer who can provide this service.

I can provide a contact at KOIZUMI that is willing to help us.

Thank you ??
