Meross has rolled out a Matter 1.4 firmware update to its entry‑level Smart Plug MSS315, marking a notable advance for budget‑priced home automation devices. According to user reports on the Homey forum, the plug’s firmware has been bumped to version 9.5.48, and the release notes indicate an upgrade to Matter 1.4 on EU hardware units.
What does this Matter update add to the Meross smart plug?
While the switch to Matter 1.4 may not introduce new user-facing features beyond bug fixes and protocol improvements, it demonstrates Meross’s commitment to keeping its lower‑cost devices in step with the evolving smart home standard. Meross told us the upgrades are as follows:
- Key Improvements: The transition to Matter 1.4 has allowed us to enhance device interoperability, reliability, and performance.
- User Experience: We’ve also addressed minor connectivity issues reported in earlier versions to ensure a more stable experience, especially in larger smart home networks.
The update places Meross ahead of some peers in the budget segment. Even premium device maker Eve, just released Matter 1.3 support for its Thread plugs earlier. Other brands, including Tapo, have remained silent on updates for comparable devices.
Meross Matter smart plugs
Meross has been active for the plug model since last year, when it launched a beta program for the MSS315. In late 2024 the company delivered Matter 1.3 firmware to testers. More recently, a test build 9.5.50 surfaced on the Home Assistant forum in December 2024, reportedly adding energy monitoring data to Matter‑compliant platforms. If confirmed, MSS315 would be among the first Matter plugs to expose real‑time energy use through Matter.
The wider Matter ecosystem is also advancing. Apple Home, SmartThings, and Home Assistant have each released Matter 1.3 and 1.4 updates, with SmartThings and Home Assistant now supporting energy sensors. Aqara announced plans last week to distribute a Matter controller update to its hubs and gateways, enabling more than 50 device types – including energy monitors – to join the standard.
Meross’s firmware push highlights a trend toward sustained software support even for low‑priced smart home products. As Matter adoption grows, consumers may expect ongoing protocol updates rather than a single, static release – potentially closing the feature gap between budget and premium devices.
