What Is the Smart Plug M3 and What Does It Do?
The Smart Plug M3 from THIRDREALITY is a compact, Matter-certified smart plug designed for Wi-Fi connectivity. It allows remote control of plugged-in appliances like lamps, fans, or chargers up to 15A/1800W, solving the issue of manual switching by enabling scheduling, voice commands, and automation. Users commonly employ it for energy management, timed operation, and integration into smart home routines without needing a hub. The plastic Type B plug meets FCC and ETL safety standards, features a space-saving design that fits tight outlets, and supports OTA updates via the 3R-Installer app. It includes customizable power-on states for safety and operates reliably on local networks.
What Does the Smart Plug M3 Work With? (Compatibility and Integrations)
The Smart Plug M3 offers direct native integration as a Matter-over-Wi-Fi device with SmartThings, Apple Home, Amazon Alexa, Google Home, Home Assistant, and Homey, requiring no proprietary hub or bridge. Setup involves scanning a QR code for seamless pairing across these platforms. Voice control works with Apple HomePod, Google Home, and Alexa-enabled devices for on/off commands. Local control functions without internet via Matter, supported directly by Home Assistant and Apple Home ecosystems using compatible controllers like HomePod or Apple TV. Cloud access enables remote control from anywhere. Limitations include local control exclusivity to Home Assistant and Apple Home; energy monitoring is absent, unlike the related M1 model.
Does the Smart Plug M3 Work With Home Assistant?
Yes, the Smart Plug M3 works with Home Assistant via the native Matter integration. It supports local control without internet, powered by Matter over Wi-Fi, and exposes on/off switching, scheduling, and power-on state restoration. No hub is required, and setup uses the standard Matter QR code pairing.
