How to prepare for the KNX Basic exam
Certification combines theory and practical work. Use explained questions to revise concepts and hands-on ETS exercises to prepare with your training centre.
In this article
Preparing for KNX Basic means understanding how an installation works and knowing how to work in ETS. A quiz can reveal confusion about addressing; it cannot replace commissioning a device.
This guide separates rules published by the KNX Association, study suggestions from CertifBus and the features available on our platform. Official sources are listed at the end. CertifBus is an independent practice tool and does not award KNX certification.

The official KNX Basic route
The Basic course lasts at least 30 hours, including exams. Theory may be taught online, while practical work and the exams take place in person. Minimum attendance is 75%.
Before booking, ask the training centre for its timetable and equipment arrangements. Explain your experience with ETS, your goals and any constraints. This gives you a basis for revising unfamiliar concepts and setting aside time for practical work.
The training centre provides the course and assessments. Progress recorded on CertifBus is neither a course registration nor a certification.
Exam format and scoring
For standard Basic, the theory test has 100 true/false statements in 90 minutes. Correct answers earn +1, incorrect answers −0.5, and unanswered statements 0. The practical assessment lasts 90 minutes and uses a KNX project. Both parts require 50% to pass.
These rules concern standard Basic; confirm the exact course you are booking. Your percentage of correct practice answers is not automatically an exam score, because the exam calculation also accounts for errors and blanks.
During a mock exam, practise reading the entire statement. When reviewing it, explain why the answer is true or false before starting another session.
Organising your revision topics
Start with a simple map of your knowledge: system operation, topology, devices, TP installation, KNX RF and ETS. Then use your centre’s course material to identify the detail you need to cover.
For each topic, connect a concept to a situation: distinguishing an individual address from a group address, reading a telegram, locating a parameter or explaining a communication object. Use the glossary to clarify terminology and questions to check whether you can apply it.
Avoid memorising wording alone. Explain the rule in your own words and find a different example. If similar statements appear contradictory, identify the condition that changes between them.
A 14-day KNX Basic preparation programme
This is a suggested CertifBus study plan. Adapt it to your course, starting level and exam date. It does not replace the official course’s minimum 30 hours. Where possible, allow 30–45 minutes of daily theory plus practical sessions with your centre; hands-on tasks may need longer.
- Day 1 — Starting point. Try 10 questions, list three weak concepts and book your ETS sessions.
- Day 2 — System operation. Explain how a command travels from sensor to actuator. Correct yesterday’s mistakes.
- Day 3 — Addressing. Distinguish individual and group addresses using two examples; sketch a small line.
- Day 4 — Topology. Revise lines, areas and couplers using your course material.
- Day 5 — TP installation. Connect power supply, wiring and installation constraints to the course instructions.
- Day 6 — Devices and objects. Identify sensors, actuators, parameters and communication objects in ETS.
- Day 7 — Review. Retry difficult questions without looking at answers. Explain each correction and adjust week two.
- Day 8 — ETS lighting. Complete exercise 1 in the practical guide: linking, download and ON/OFF checks.
- Day 9 — ETS dimming. Complete exercise 2 and distinguish DPT 1.001, 3.007 and 5.001.
- Day 10 — Diagnostics. Complete exercise 3: observe, isolate one cause, fix and retest.
- Day 11 — KNX RF and neglected topics. Check the centre’s syllabus and cover remaining gaps.
- Day 12 — Theory mock. If your access allows, complete 100 statements in 90 minutes. Apply penalties when calculating the score and review blanks.
- Day 13 — Targeted corrections. Sort mistakes into unknown concepts, missed conditions and rushed reading. Revisit the three most common causes and repeat a weak practical task.
- Day 14 — Light revision and logistics. Confirm time, travel, equipment and centre instructions. Read your error notes and allow time for rest.
With fewer than 14 days, combine related theory days but keep ETS sessions and mock analysis. If you are a beginner or lack equipment, spread the plan over three or four weeks with your centre. If you already know the material, spend more time on neglected topics and different ETS briefs. No quiz result guarantees a pass.
Preparing the practical assessment
Ask for exercises that take you through a complete project: understand the brief, organise devices, connect functions, commission the installation and check the result. Keep a list of operations for which you still need assistance.
Before enrolling, confirm the teaching and examination language, access to equipment and ETS, dates, retake arrangements and total price. Fees and funding options vary; this guide does not assume a universal price or guaranteed subsidy.
Your training centre is the point of contact for logistics and practical assessment. Online explanations support your preparation, but they cannot independently demonstrate that an installation works.
Using CertifBus for theory practice
The free trial provides 10 questions per session, selected from a pool through daily rotation. Learning mode shows an explanation after each answer and may include multiple-choice questions to explore concepts. Exam mode uses true/false statements.
Paid access opens the Basic practice bank and full mock exams for the selected period. The volume displayed on the site reflects questions in the active syllabus, rather than every stored record. Check the offer page for current availability and prices.
In My space, session history, topic results and skills help you choose what to revise next. Indicators with too little evidence are labelled accordingly. Our questions are independent practice material, not a copy of the official examination.
