Prepare for the RESIma/STSmi master integrator scope with whole-premise design, home controllers, gateways, IP convergence, audio, video, data, security, environmental controls, troubleshooting, debugging, modification planning, 75 questions, and 2-hour timing.
RESIma is the legacy master residential integrator page for ETA’s advanced smart-home integration role; ETA’s current catalog frames the active master path as Smart Technology Systems Master Integrator (STSmi).
Use these checkpoints to confirm the current format, delivery rules, scoring, and test-day setup before building the full plan.

This page preserves the RESIma slug while aligning the content to ETA’s current master smart-home integrator language. The scope is advanced residential and light-commercial electronics integration across planning, design, networking, controls, commissioning, troubleshooting, and modification work.
ETA’s current catalog lists Smart Technology Systems Master Integrator (STSmi) as stand-alone, maintenance required, 4-year term, no hands-on requirement, 75 questions, a 75% passing score, and 2 hours allowed to test.
Study site planning, new construction and retrofit design, home controllers, gateways, IP convergence, audio-video, data networks, security-surveillance, environmental controls, control protocols, diagrams, documentation, installation planning, commissioning, troubleshooting, debugging, and modification planning.
The master level assumes strong command of the core RESI/STS integration domain and adds broader design ownership, system architecture decisions, cross-subsystem coordination, and advanced fault isolation.

ETA Master Residential Electronics Systems Integrator (RESIma) represents the advanced residential and light-commercial systems integrator role. O*NET describes the Master RESI professional as proficient in core RESI skills and in planning and designing electronics and communications equipment systems and layouts for new and existing construction. The role includes designing the entire system and network for audio, video, data, control of security, and environment so the system functions as one IP bit stream converged at the home controller, plus troubleshooting, debugging, and planning installation or modification work.
ETA's current certification catalog now presents the master smart-home path as Smart Technology Systems Master Integrator (STSmi). ETA lists STSmi as a stand-alone certification with maintenance required, a 4-year term, no hands-on requirement, 75 questions, a 75% passing score, and 2 hours allowed to test. Preparation for the RESIma/STSmi scope should cover full-system design, site planning for new and retrofit construction, home controllers, gateways, IP convergence, audio-video, data networking, security and surveillance, environmental controls, control protocols, documentation, commissioning, troubleshooting, debugging, modification planning, and integration across the smart-home subcategories.
ETA RESIma refers to the master residential electronics systems integrator path for advanced smart-home and light-commercial system design, planning, troubleshooting, and modification work.
ETA’s current catalog frames the active master smart-home path as Smart Technology Systems Master Integrator (STSmi), while RESIma is the legacy residential master integrator name still used in some workforce references.
ETA’s current STSmi listing shows 75 questions with 2 hours allowed to test.
ETA lists a 75% passing score for Smart Technology Systems Master Integrator.
No. ETA’s current STSmi exam listing shows no hands-on requirement.
For each scenario, identify the controller, gateway, network, media paths, controlled subsystems, power, and security boundaries before solving details.
Separate new-construction planning from retrofit modifications because cabling paths, equipment placement, documentation, and constraints change.
Practice explaining how audio, video, data, security, and environmental controls converge logically and physically at the home controller.
Build fault trees that cross cabling, addressing, protocols, equipment configuration, controller logic, gateway access, and user-device behavior.
Before scheduling, confirm whether the testing administrator lists this path under RESIma, STSmi, or the current Smart Technology Systems master name.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
