> The HomeKit Open Source ADK is an open-source version of the HomeKit Accessory Development Kit. It can be used by any developer to prototype non-commercial smart home accessories. For commercial accessories, accessory developers must continue to use the commercial version of the HomeKit ADK available through the MFi Program.

So only the "device" part, sadly not the "controller" part. So you'll still need a iOS device to setup stuff in your house, I tried it yesterday with only my iMac to no avail.

But still it's a step in the right direction.
