Shelly 1PM Mini vs Plus 2PM Specs
Channel Count
The Shelly Plus 2PM 2-Channel Smart Relay handles two separate circuits. You can control two different appliances or lights on the same phase with one device. This reduces your wiring footprint significantly. In contrast, the Shelly 1PM Mini Gen4 Smart Switch is a single-channel unit. It manages only one load at a time. If you need to monitor and switch two independent devices, the Plus 2PM offers more flexibility. The Mini is better if you only have one circuit to control.
Amperage Rating
Power handling differs between these two models. The Shelly Plus 2PM supports up to 16A per channel, with a peak of 18A. This allows it to handle heavier loads for larger appliances. The Shelly 1PM Mini Gen4 Smart Switch is rated for 8A. This lower limit makes it suitable for smaller devices like fans, lights, or kitchen gadgets. You must check your appliance's amperage requirements. If a device draws more than 8A, the Mini cannot handle it safely. The Plus 2PM offers higher capacity for demanding loads.
Connectivity Standards
Wireless options vary significantly. The Shelly 1PM Mini Gen4 supports Wi-Fi, Matter, and Zigbee. This multi-protocol support allows it to integrate with various smart home ecosystems without a dedicated hub for Zigbee devices. The Shelly Plus 2PM relies on Wi-Fi and Bluetooth. It lacks native Zigbee or Matter support in its standard configuration. If your home automation system depends on Zigbee sensors or Matter commands, the Mini provides broader compatibility. Bluetooth on the Plus 2PM is useful for local setup but does not replace Wi-Fi for remote control.
Physical Dimensions
Size matters for tight electrical boxes. The Shelly 1PM Mini Gen4 measures 1.34 inches in width and 1.14 inches in height. It weighs 0.67 ounces. The Shelly Plus 2PM is slightly larger, at 1.65 inches wide and 1.46 inches high. It weighs 0.99 ounces. Both share the same depth of 0.63 inches. If you are fitting these into a standard wall box or behind a small appliance, the Mini’s compact footprint provides more clearance. The Plus 2PM is still compact but takes up more space inside the enclosure.
Smart Home Ecosystem
Integration capabilities depend on your existing setup. The Shelly Plus 2PM explicitly lists compatibility with Alexa and Google Home in its specifications. This makes it easy to add voice control for your two channels. The Shelly 1PM Mini Gen4 highlights Matter and Zigbee support. Matter ensures future-proof compatibility with major platforms, while Zigbee allows connection to hubs like Home Assistant or SmartThings. If you rely on direct Alexa or Google Home routines without a hub, the Plus 2PM is the clearer choice. If you use a hub, the Mini’s Matter support is advantageous.
Choose the right Shelly relay
Users wanting Matter and Zigbee support
The Shelly 1PM Mini Gen4 supports Matter and Zigbee alongside Wi-Fi. This allows broader integration with modern smart home ecosystems without needing a separate hub. Its compact 1.34-inch width fits tight spaces behind sockets or inside appliance casings. You get precise power monitoring for devices up to 8A with free historical data storage.
Users needing to control two circuits
The Shelly Plus 2PM handles two separate channels with up to 16A per circuit. This lets you control two different appliances or lights on the same phase using a single device. It reduces your wiring footprint significantly while providing individual power metering for each channel. You can monitor consumption and manage energy use for both circuits independently.
Users preferring Bluetooth connectivity
The Shelly Plus 2PM includes Bluetooth connectivity in addition to Wi-Fi. This provides flexible local control options and can function as a Wi-Fi repeater. It supports Alexa and Google Home for voice commands. You can control electric circuits, home appliances, and office equipment individually through the app or manual switch, with detailed energy tracking for each channel.
