Objective
Design a small cross-device routine that remains predictable when an internet connection or a vendor service is unavailable.
What would be tested
- Map discovery, pairing, permissions, and the dependencies of each candidate device.
- Trace a sensor event through a local controller to a simulated actuator.
- Interrupt the network and inspect recovery, repeated messages, and delayed actions.
- Check whether manual control remains available when an automation fails.
Current observations
No hardware compatibility claims or device test results are available. The concept starts with simulated devices so failure scenarios can be designed before hardware selection.
Next step
Write a device capability matrix and choose one routine with a clear manual fallback.
