When it comes to smart relays and plugs, Shelly has always been a benchmark for flexibility and local control. With the launch of the new Gen3 line, the manufacturer raises the bar, and the Shelly Plug M Gen3 is the perfect example of "heavy-duty hardware inside a pocket-sized body."

If you want to monitor your electronics' power consumption or extend your smart network without blocking adjacent outlets, here is why this new model deserves your full attention:

🏗️ Gen3 Hardware: What’s Under the Hood? 🤓

The biggest change isn't visible from the outside, but rather in how the plug processes information. Moving to the new Gen3 architecture brings major upgrades:

• The New Shelly Processor: The plug comes equipped with an expanded flash memory chip, providing instant response times and significantly higher connection stability.

• Ultra-Compact Format: The "M" (Medium/Mini) design is specifically engineered not to cover neighboring outlets. You can use it in crowded power strips without any issues.

• Maximum Load: Despite its reduced dimensions, the plug successfully handles heavy-duty appliances, offering high switching safety.

• Integrated Bluetooth Gateway: In addition to the Wi-Fi connection, it functions as a bridge for other Bluetooth sensors in your home (such as Shelly's temperature or motion sensors).

🧠 Ready for the Future: Native Matter Support 🏠🌐

The 3rd generation is designed with one goal in mind: total interoperability. Thanks to its expanded memory and new firmware, the Shelly Plug M Gen3 receives full support for the Matter standard.

This means you are no longer tied exclusively to the Shelly app. The plug integrates natively and locally into:

• Apple Home

• Google Home

• Amazon Alexa

• Home Assistant (via Matter or the native Shelly integration)

⚡ Precise Energy Monitoring & Local Scripting

For advanced users (Power Users), Shelly remains a customization paradise:

• Real-time Measurement: See exactly how many watts your computer, TV, or refrigerator is consuming, and store the history locally or in the cloud.

• mJS Scripting: The plug supports complex scripts running directly on its internal processor. You can program scenarios like: "If power drops below 5W for 10 minutes (PC turned off), cut the power supply completely." 🧠📜

• Local Webhooks: Send HTTP commands directly to other devices in the local network without passing through the internet or the central router, ensuring zero latency. 🛡️💻

🛠️ Smart Use Cases

• Appliance Protection: Configure overvoltage or overcurrent limits directly from the local web interface. The plug will disconnect instantly if the electrical grid becomes unstable.

• Office Automation: Use consumption monitoring as a trigger. When you turn on your main monitor and consumption rises, the Shelly Plug M Gen3 can automatically command the ambient desk LED strip to turn on.

• Network Extension (Wi-Fi Range Extender): The device can also function as a Wi-Fi range extender to ensure coverage in isolated areas of the house.

✅ Technical Verdict

The Shelly Plug M Gen3 brings the maturity that the smart ecosystem truly needed. You no longer have to choose between small dimensions, processing power, and compatibility with Apple or Google. The new hardware architecture delivers everything in a robust, stable package focused on local control.
