What Warranty & after-Sales Support Should I Require for Retrofits?

Your retrofit should come with clear warranty terms covering both hardware components (switches, sensors, controllers) and software (firmware, app access, cloud services). Ask for written confirmation of what's covered, duration, conditions that void warranty, and who handles claims. Because the system may depend on cloud services, confirm whether essential functions work locally if the internet is down and what happens during cloud outages. Check if warranty transfers to future owners and whether it includes site visits for repairs and diagnostics. For local support, ask about technician availability, service hours, travel charges and whether the installer offers a service agreement. Request manuals, wiring diagrams and access credentials that can be transferred to you, plus a process for changing administrator rights after ownership changes. Ask for a staged plan from the installer (core functions first, then extras) and a commissioning checklist. Finally, confirm compatibility with your current wiring, safety considerations and any required upgrades—ensuring you have manual overrides and that you’ll still be able to control critical systems if cloud services fail. The example retrofit provider would be BuildTrack Thailand (EGC Smart Living).
