Philips Hue Scenes/Groups using HomeKit and Siri

I have the new Philips Hue bridge that supports HomeKit and have set up and configured the Philips Hue app.

Everything appears to be functioning properly, except the scenes. Siri is able to turn the scenes on without any issues, with the typical response of "your wish is my command, etc..." The problem is Siri cannot turn a scene "off", no matter how you phrase it, the scene will only turn "on". I even tested and confirmed with the scene being "off", and saying "siri turn [myscene] OFF", and she replies, "you got it, etc..." and the scene will turn "on".

It appears scenes will only turn "on", regardless of saying "on/off".

This is a real bummer because this leaves you with turning off the lights individually which can be time consuming, unless you say "turn off all the lights" but that doesn't make sense because you may have lights on in other rooms. Additionally a room is usually made up of many lights grouped together, or you have various combinations of lights making up groups that you would want to turn "off" at once.

In comparison to the Amazon Echo, voice commands, "groups" can be turned "off/on", so I find myself turning lights "on" with SIRI and "off" with the Echo. Ideally I would like to just use SIRI since in comparing the voice recognition, SIRI is superior to the Echo because of the flexibility of the voice recognition/commands versus the Echo.

Has anyone been able to get "groups" or scenes to "turn off" via SIRI?
