This is mentioned in the homekit controller doc (HomeKit Device - Home Assistant)
I CAN’T SEE ANY EVENTS GENERATED FOR “STATELESS” ACCESSORIES
This is expected. The only way to use stateless accessories like some doorbells, buttons or remotes with Home Assistant is through device automations. Home Assistant doesn’t create duplicate events for device automation triggers, so for example you won’t be able to watch them with the events developer tools.
I’m just wondering why not expose these HK events through native HA event bus? I understand that automations can be done with HA for this, but I’m using Appdaemon for all my automations. If these HK events are not exposed as HA events, then Appdaemon will not be able to receive them.
For now I’m using HA automation to fire separate HA events, but it’d be nice if this can be without this workaround.
Thanks!
