01
Everyday control
What must still work from the wall or thermostat?
Lighting, heating and other daily functions should keep an obvious control path. Decide what a physical switch, native thermostat or device button must do before adding an app, bridge or automation.
02
Scope
Is this one focused job or several connected systems?
One relay, lighting scene or heating schedule may be complete on its own. Cross-brand routines involving sensors, lights, climate, energy or security create a stronger case for central coordination.
03
Dependencies
Which features need internet, a bridge or a subscription?
Local device control, app access, remote commands, voice and history can follow different paths. Check the exact model and feature instead of assuming that “smart” means cloud-only or fully local.
04
Ownership
Who maintains, transfers and recovers the system?
Record the household accounts, bridges, controller, backups and update responsibility. The right design remains understandable when the phone changes, the broadband fails or the property changes hands.
