Medium level questions
Q01
Matter Spec 1.0 already supports the core residential device types: OnOff Light, Dimmable Light, Color Temperature Light, Extended Color Light (RGB), Smart Plug, Door Lock, Contact Sensor, Motion Sensor, Window Covering, Thermostat and more.TrueFalse4. Device types· Gerätekategorien· MediumCorrect answerTrueLearning tipThe Spec 1.0 release covered the residential core: lighting in four flavours (OnOff, Dimmable, Color Temperature, Extended Color), Smart Plug, Door Lock, the common sensor family (Contact for doors and windows, PIR Motion, Temperature, Humidity, Illuminance), Window Covering for blinds and shutters, and Thermostat. Subsequent releases broadened the catalogue: Spec 1.1 and 1.2 added Robot Vacuum, Smoke and CO alarms, Air Quality, Ovens and Washing Machines, Spec 1.3 brought energy management and EV charging, and Spec 1.4 introduced cameras and advanced presence detection.
Q02
The Matter specification evolves quickly: 1.0 (October 2022, core devices), 1.1 (May 2023, bug fixes), 1.2 (October 2023, new device types), 1.3 (May 2024, energy management), 1.4 (October 2024, home batteries and Fabric sync), with 2.0 planned from 2025 onward.TrueFalse7. Versioning· Matter 1.0 bis 1.4· MediumCorrect answerTrueLearning tipThe release cadence is roughly semi-annual: 1.0 in October 2022 delivered the residential core, 1.1 in May 2023 was a stabilisation release, 1.2 in October 2023 added Robot Vacuum, Smoke and CO Alarms and Air Quality sensors, 1.3 in May 2024 brought energy management and EV charging, 1.4 in October 2024 introduced home batteries and Multi-Admin Fabric Sync, and 2.0 was on the roadmap for 2025 as a major evolution (timeline pending as of mid-2026). The rhythm is aggressive compared with KNX (V1 in 2002, V3.0 only in 2024), so backward compatibility is a first-class requirement of the spec.
Q03
The Matter SDK is fully open source (Apache 2.0) on GitHub (project-chip/connectedhomeip) with more than one hundred active contributors, which lets OEMs ship Matter devices quickly and lets hobbyists and Home Assistant integrate Matter directly.TrueFalse9. Open source· Project-CHIP· MediumCorrect answerTrueLearning tipThe Connected Home over IP repository is published under the Apache 2.0 licence, which authorises unrestricted commercial use. It targets a wide range of platforms (Linux, ESP32, Nordic Semiconductor, NXP, Silicon Labs, Infineon) and ships a CLI client called chip-tool plus sample applications for both devices and clients. Every major ecosystem (Apple, Google, Amazon, Samsung) contributes back to this codebase, which is unusual in the smart-home space and is one of the main reasons interoperability has actually held up across vendors.
Q04
Matter 1.x still has clear gaps compared with proprietary ecosystems: no native camera support until 1.4, limited cross-ecosystem cloud sync, basic power management for battery devices and audio/video streaming still on the roadmap.TrueFalse10. Limitations· Matter-1.x-Lücken· MediumCorrect answerTrueLearning tipCameras only entered the spec in 1.4 and rollout across controllers is gradual. Audio and video streaming are not yet covered and are tracked for a later release. Cross-ecosystem cloud synchronisation is limited because each ecosystem keeps its own cloud and metadata; Multi-Admin Fabric Sync (added in 1.4) standardises only a subset of this. Cross-Fabric automations are still each ecosystem's private business, with no portable rule format. Energy management (added in Spec 1.3) is functional but still coarser than dedicated energy platforms. The roadmap is closing these gaps quickly compared with older standards.
