Homey is Matter 1.5 certified
Athom’s Homey received Matter 1.5 certification from the Connectivity Standards Alliance. The cert applies to Homey Pro (2023–2026), Homey Pro mini, and Homey Self-Hosted Server. Homey Pro and Pro mini include a built-in Thread border router; Self-Hosted Server uses Matter-over-Thread through the Homey mobile app when a Thread border router is already on the network.
CSA lists the product as a software component, certificate ID CSA26025SWC60263-M1, specification version 1.5, certified 29 June 2026, firmware 13.3.0. That is a controller milestone, not a new device type.
