The application is one part of the system
The mobile app presents data and actions made available by the installation. Depending on the operation, a request can cross the app, an authenticated Hombee service, the installation connection, Home Assistant and the final device.
Keep the boundaries separate
- A local UI update proves only that the interface accepted the interaction.
- A server acknowledgement proves that a request was accepted, not that a physical device reached the target state.
- A reported entity state reflects the connected system and can arrive after the command.
- Some home behaviour continues locally when the internet path is unavailable, while remote access and cloud services require connectivity.
For troubleshooting, record the first boundary that did not progress rather than classifying every symptom as a generic outage.
