Apple HomeKit with Yeelight RGB is compatible?

Hello, I wondering if the yeelight is compatible with Apple HomeKit now. I’m waiting that ships and I want to know. Thank you!

It is in development.

Is it could be compatible through a software update or I must to buy another version?

Probably no need for a hardware upgrade.

Via software auth. For now you can control your yeelights with Siri via the shortcuts features within Yeelight app.
