Smart Plug EU Compliance Guide

Smart plugs combine mains-voltage electrical safety with radio connectivity, electronics and consumer-product use. The final compliance scope depends on switching design, load rating, radio technology and intended use.

Potentially relevant compliance areas

Evidence worth preparing

Rated voltage, current and load specification
Radio module and antenna specification
Electrical safety and RED test evidence
Relay and thermal-protection information
Material declarations
Labels, instructions and EU declaration

Questions that change the compliance path

  1. Which radio technologies are enabled?
  2. What is the maximum rated load and switching current?
  3. Is the product intended for indoor or outdoor use?
  4. Does the design include overload or over-temperature protection?
  5. Is energy-monitoring functionality included?

Frequently asked questions

Does a Wi-Fi smart plug fall under RED?

A smart plug that intentionally uses Wi-Fi, Bluetooth or another radio technology can fall within the Radio Equipment Directive, depending on the final product configuration.

Does RED replace electrical-safety assessment?

No. Radio conformity does not remove the need to assess mains-voltage safety and the other applicable product requirements.

Should the switching relay be part of the compliance review?

Yes. Relay rating, heating, endurance and protective design can be important to the finished-product safety case.
