CRA compliance for Smart home gateway / hub
Critical class (Annex IV)
About CRA compliance for Smart home gateway / hub
A smart home gateway aggregates a local network of connected devices, runs the firmware that brokers control commands, and often exposes a remote access surface. Because it sits between the local network and the internet, its security posture directly affects every device behind it. CRA documentation for a gateway therefore starts from the gateway's own components and update mechanism, and covers the remote-access surface explicitly.
What the Critical class (Annex IV) means for this product
Critical products are listed in Annex IV and are subject to the strictest conformity assessment routes under Article 47 and Annex VIII, always with third-party involvement. The technical documentation and its traceability are central because the notified body's examination and subsequent surveillance rest on them.
Where this device type sits in the Regulation
In the Regulation's own structure, 'smart home products with security functionalities, including smart home gateways, smart home hubs and smart home central points of control' are named in Annex III Class I (Regulation (EU) 2024/2847, Art. 32(2)). Whether THIS specific gateway has such security functionalities and therefore falls in that named category is the manufacturer's guided questionnaire answer, never an assumption of this site.
Conformity assessment
EU-type examination + conformity based on full quality assurance (Module H), notified body required
Annex III / IV structure
Annex IV (critical) (Regulation (EU) 2024/2847, Art. 47)
The Regulation's own structure names these 3 items in Annex IV:
- hardware devices with security boxes
- smart meter gateways and other advanced security purpose devices for secure cryptographic processing
- smartcards and similar devices, including secure elements
This is the Regulation's own structure (Regulation (EU) 2024/2847, Annex IV), not an assessment of any specific product. Whether a particular product falls within a named item is the manufacturer's guided questionnaire answer, never an assumption of this site.
Key obligations
- Strictest conformity assessment route under Article 47 and Annex VIII
