Diagnose a room-control fault by separating the switch or driver, curtain mechanism and aircon interface from gateway or scene logic. HJ confirms the responsible electrical and HVAC parties, approves the specific correction, and retests each included load and local control.
Conceptual planning path — not an as-built drawing or project photograph.
Tell us the fault and your location. Diagnostic attendance, repairs, parts and any travel charges are confirmed with you before work.

It sits in Smart Home Service under Smart Home. The final deliverable is shaped by the intended outcome, the installed or proposed environment and the interfaces that must be owned, supplied, integrated and tested.
Affected room/load, switch/driver, curtain motor/limits and aircon interface models, physical versus app behaviour, recent changes and responsible specialist access.
From the initial brief to the handover record: what to prepare, check and confirm with HJ.

Confirm the exact devices, gateway and supported load interfaces with the account owner. Separate local controls from app, internet and cloud functions; electrical, HVAC and moving-gate work remain with the responsible appointed parties.
Test the included points, scenes and schedules plus actual local operation. Record power/network loss, unavailable devices and supported recovery; never bypass electrical, HVAC, gate or life-safety protection to make a scene operate.
Handover the room/device and scene list, owner and shared-user permissions, supported configuration backup, witnessed tests, local recovery and unresolved limits. Parts, vendor-cloud support and further integrations are separately confirmed.
HJ coordinates assessment, engineering, installation, integration, testing and lifecycle support only for the scope recorded in the quotation. ISD handles catalogue, model, datasheet, supply and availability enquiries. Customer, consultant, builder and appointed-specialist responsibilities remain explicit.
Final scope, quantities, compatibility, access, programme, availability and responsibility are confirmed during assessment and quotation.
Installed platform, authorised ownership, parts compatibility and serviceability are checked before any repair or restoration outcome is proposed.

Use the answers as a planning boundary; site conditions and written scope remain decisive.
No. Check each load locally, then trace the supported gateway and scene path. A driver, curtain mechanism, aircon interface and automation rule can fail independently; approve the identified correction and retest retained functions.
