I have seen mention of the UCM/Pi module and Node Red supporting two way HomeKit connectivity.
I suspect this is via HomeBridge rather than an official integration with HomeKit.
Is there any plan to get official HomeKit approval from Apple?
Can it actually allow Comfort to both access HomeKit devices and to let HomeKit access Comfort devices? I know that so far uniquely the HomeAssistant software can do this but most systems only allow exporting to HomeKit via HomeBridge.
