Shelly 1PM Mini Gen4 – Ultra-Compact Smart Switch with Power Monitoring

Take control of your devices and your energy consumption with the Shelly 1PM Mini Gen4 an ultra-compact smart relay with built-in power monitoring and support for Wi-Fi, Zigbee, Matter and Bluetooth.

Measuring just 29 × 34 × 16 mm, the Shelly 1PM Mini Gen4 is small enough to fit behind many existing wall switches and sockets, making it an excellent solution for smart-home retrofits where installation space is limited.

Unlike a conventional smart switch, the 1PM Mini Gen4 combines remote switching with real-time energy monitoring, allowing you to see how much power connected devices are using and incorporate energy consumption into your automations.

With support for local control, advanced automation and multiple smart-home protocols, it is equally at home in a simple smart lighting installation or an advanced Home Assistant setup.

Key Features & Benefits

⚡ Smart Switching with Real-Time Power Monitoring

The built-in power meter allows you to monitor the electrical performance and energy usage of connected loads.

Track information such as:

• Voltage
• Current
• Instantaneous power
• Energy consumption

Use this information to identify energy-hungry appliances, monitor individual circuits and build smarter energy-management automations.

For example, you can use power consumption as an automation trigger to detect when an appliance starts or finishes operating.

🔌 8A Smart Relay in an Ultra-Compact Package

The Shelly 1PM Mini Gen4 supports loads of up to 8A at 240V AC, making it suitable for many everyday residential applications.

Ideal for controlling:

• Lights
• LED lighting
• Fans
• Small appliances
• Pumps
• Extractor fans
• Heating equipment within the rated load
• Other suitable electrical loads

Its tiny 29 × 34 × 16 mm enclosure makes it particularly useful for retrofit installations where conventional smart relays may simply be too large.

🌐 Wi-Fi, Zigbee, Matter & Bluetooth

The Shelly 1PM Mini Gen4 provides exceptional connectivity flexibility.

Choose the protocol that best suits your smart-home installation:

Wi-Fi 6
Connect directly to your existing Wi-Fi network without requiring a dedicated hub.

Zigbee 3.0
Integrate the device into a compatible Zigbee network and benefit from the advantages of a dedicated low-power smart-home protocol.

Matter
Enjoy simplified interoperability with compatible smart-home ecosystems and combine devices from different manufacturers.

Bluetooth 5.0
Useful for device commissioning and Bluetooth ecosystem functionality.

This multiprotocol approach makes the 1PM Mini Gen4 a highly adaptable choice for modern smart homes.

Good to know: The Shelly 1PM Mini Gen4 ships in Matter mode by default. Switching to Zigbee mode (via a simple button sequence) disables Matter.  Wi-Fi and Bluetooth stay active either way.

🏠 Excellent for Home Assistant

The Shelly 1PM Mini Gen4 is particularly well suited to Home Assistant installations.

Use the relay and energy measurements to create sophisticated local automations, dashboards and energy-monitoring systems.

For example:

Turn on a fan when a light is switched on.

Monitor the energy consumption of an appliance.

Create an alert when an appliance draws more power than expected.

Track the operating time and energy usage of individual devices.

Automate devices based on their actual power consumption.

The device also supports advanced technologies such as MQTT, webhooks, scripting, WebSockets and HTTPS, providing plenty of flexibility for advanced users.

📱 No Dedicated Hub Required for Wi-Fi

When operating over Wi-Fi, the Shelly 1PM Mini Gen4 connects directly to your network.

Control your device through the Shelly Smart Control platform, compatible smart-home systems or its local interface.

This means you can start with a straightforward Wi-Fi installation and expand into more advanced automation later.

🛡️ Built-In Electrical Protection

The Shelly 1PM Mini Gen4 incorporates protection features designed to help safeguard the device during operation, including monitoring for conditions such as:

• Overheating
• Overcurrent
• Overpower
• Overvoltage

Appropriate external circuit protection should still be provided as required by the electrical installation.

📐 Designed for Retrofit Installations

One of the biggest advantages of the Shelly 1PM Mini Gen4 is its exceptionally small size.

At just 29 × 34 × 16 mm, it can be installed in many locations where larger smart relays won’t fit.

This makes it particularly useful for:

• Retrofitting existing homes
• Smart lighting upgrades
• Behind wall switches
• Behind sockets
• Appliance automation
• Energy monitoring projects
• Home Assistant installations
