Mozilla has debuted an implementation of WebThings Gateway, an open-source router firmware for smart home gateways. The firmware allows users to monitor and control their smart home devices directly over the web without a middleman. It supports various protocols, including HomeKit, ZigBee, and Thread, and can run on devices like Raspberry Pi and Turris Omnia. The gateway is designed to be self-hosted and locally controlled, with optional add-ons for features like offline voice control.
