SAA-Certified Smart Switches in Australia: Why Certification Matters Before You Buy
Short answer: any smart switch wired into 230 V mains in Australia must hold Australian electrical safety approval (still called SAA approval) and be installed by a licensed electrician. Check the approval number on the device and on the national EESS register before you buy, including Amazon and AliExpress imports. Arklyfe's StellarTrack Matter switch is approved under certificate GMA-528353-EA.
