This may not strictly be a Homekit Bridge issue but I'm curious if other users are seeing this. After upgrading to iOS 12, Siri now will not send an on or off command to a device if she thinks the device is already in that state. This affects all of my X10 light switches after I turn them off manually. I don't see any attempt to control them in the Indigo log or anywhere else except that Siri responds as if she controlled the device. I don't think there is any Siri or Homekit log available so I don't know how to check further.
Alexa controls the devices as before so no problem there.
I plan to contact Apple, at least with a suggestion to revert to the old behavior, but I figured I'd check here first to confirm it's not specific to my system.
Thanks.
