Shelly 1PM Mini Gen3 | Compact 8A Switch with Power Metering and Wi-Fi

Compact switching and metering up to 8A

Not every flush-mounted box offers space for a full-fledged switching module. The Shelly 1PM Mini Gen3 solves this with a compact size and yet full functionality: switching up to 8A and real-time power metering in one module. For lighting and other light loads, this is a practical solution if you want to monitor consumption per circuit.

Power supply and connectivity

The module operates on 110-240V AC or 24-30V DC and connects to your network via Wi-Fi 2.4 GHz. No hub, bridge or extra gateway is needed. The module features a local web interface and can communicate via the Shelly API and MQTT.

Functionality and settings

The relay switches a maximum of 8A and measures power in real-time. You can read watts, amperes, and kilowatt-hours per connected device. The module supports local automations and smart logic without relying on an external cloud.

• Resistive: incandescent bulbs, halogen, heating devices.
• Capacitive: electronic equipment with capacitors.
• Inductive with RC Snubber: LED lighting, LED drivers, fans, and small motors.

For inductive loads, an RC Snubber is strongly recommended to dampen inrush current peaks and limit relay wear. Also check out the Shelly RC Snubber.

Expansion and accessories

The Shelly 1PM Mini Gen3 is suitable as a compact replacement where space is limited. For heavier loads or larger installations, the larger Shelly 1PM Gen3 is a logical step. The RC Snubber is a useful addition for LED drivers, motors, and other inductive loads.

Safety and reliability

The module has built-in protection against overheating, overload, and overvoltage. The internal temperature sensor continuously monitors the module and can switch off the output if the temperature is too high. This better protects the installation during intensive use or in tight installation conditions.

Home Assistant

The Shelly 1PM Mini Gen3 integrates directly into Home Assistant via the local Wi-Fi API. No additional hardware or cloud connection is required.

• Connect the module to your 2.4 GHz Wi-Fi via the Shelly app or the local web interface.

Specifications

Frequently asked questions

What is the difference with the larger Shelly 1PM Gen3?

The Mini is more compact and switches up to 8A. The larger Shelly 1PM Gen3 can handle higher loads up to 16A and is therefore more suitable for heavier devices.

Do I need a hub?

No. The module works directly via Wi-Fi and can integrate locally with Home Assistant.

Do I need to use an RC Snubber?

For inductive loads such as LED drivers, fans, or motors, an RC Snubber is strongly recommended to limit inrush current peaks.

Does this module work with Homey?

Yes, via the official Shelly app for Homey Pro.

Is Apple Home supported?

Not natively. For Apple Home, use other Shelly models or another compatible solution.
