Hi Bruce B,
trigger:
- platform: event
event_type: zha_event
event_data:
device_id: ---your cube device_id here ---
Should trigger any and all things your cube does.
It is the basis of most Cube Blueprints if you want further reference. But it will give you a lot of traffic, so you may want to condition that down a bit to cut out some noise.
Perhaps just taking control of someones blueprint is a better way to start what you are asking (or just using their blueprint).
