CRA compliance for Smart home gateway / hub
Important class II (Annex III)
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 Important class II (Annex III) means for this product
Important class II products sit in the higher-risk half of the Annex III list. Conformity assessment generally requires third-party involvement: an EU-type examination by a notified body (Module B) followed by conformity to type (Module C), or a full quality assurance route (Module H). The technical documentation under Annex VII is the basis for that examination, so its completeness and traceability to the product state matters directly.
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 (Module B+C) or full quality assurance (Module H), notified body required
Annex III / IV structure
Annex III, Class II (Regulation (EU) 2024/2847, Art. 32(3))
The Regulation's own structure names these 4 categories in Annex III, Class II:
- hypervisors and container runtimes supporting virtualised execution of operating systems
- firewalls, intrusion detection or prevention systems used for security purposes
- tamper-resistant microprocessors
- tamper-resistant microcontrollers
This is the Regulation's own structure (Regulation (EU) 2024/2847, Annex III Class II), not an assessment of any specific product. Whether a particular product falls within a named category is the manufacturer's guided questionnaire answer, never an assumption of this site.
Key obligations
- Third-party conformity assessment via a notified body before placing on the market
- EU-type examination certificate, then conformity to type for each production unit
- Annex VII technical documentation complete and traceable to the assessed type
- Ongoing surveillance of the certified type where the module requires it
