As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The Shelly 2PM Gen4 offers dual-channel control with built-in power metering. You might look for shelly 2pm gen4 alternatives if you need a single channel, a different size, or a hub-dependent setup. This relay handles 16A per channel and connects via Wi-Fi, Zigbee, and Matter. It works without a central hub, which simplifies installation for many users. However, some buyers prefer compact wall switches or plug-in solutions. Others may already have a Zigbee hub and want to reduce Wi-Fi congestion. The devices on this list share key specifications with the original product. They all support smart home integration and offer remote control capabilities. Each alternative fits specific use cases, from tight electrical boxes to multi-outlet management. You can choose based on your existing ecosystem and physical space constraints. This guide helps you compare features like connectivity protocols and load limits. We focus on how each device performs in practical scenarios. Your choice depends on whether you need energy monitoring, single-circuit control, or retrofitting options. The following selections cover a range of needs while maintaining compatibility with major platforms.
Our top pick: Shelly 2PM Gen4 2-Channel Relay.
How each alternative compares
THIRDREALITY Zigbee Smart Plug 4-Pack
The THIRDREALITY Zigbee Smart Plug 4-Pack shifts from a hardwired relay to a plug-in outlet solution. You lose the dual-channel 16A per-circuit control found in the Shelly, but you gain four separate outlets for lower-load devices. This model relies on Zigbee connectivity, meaning you must have a compatible hub, whereas the Shelly operates without one. The physical form factor is larger at 2.6 inches long, designed to sit in wall sockets rather than electrical boxes. It is ideal if you want to monitor multiple lamps or small appliances independently without rewiring your home.
SONOFF Compact Zigbee Smart Switch
The SONOFF Compact Zigbee Smart Switch is a single-channel device, so you cannot control two circuits like the Shelly 2PM Gen4. It requires a Zigbee hub for operation, removing the hub-free Wi-Fi option available in the original. The dimensions are 1.68 inches square, making it slightly wider but thinner at 0.79 inches, which helps fit into tight wall boxes. It lacks the built-in power metering of the Shelly, focusing instead on basic on-off control for lighting. Choose this if you need a smaller footprint for retrofitting standard switches and already have a Zigbee hub in place.
Shelly 1 Mini Gen4 Smart Relay Switch
The Shelly 1 Mini Gen4 reduces the channel count from two to one, limiting you to controlling a single light or appliance. It shares the same 0.63-inch depth and Zigbee connectivity, but drops Wi-Fi and Matter support in favor of a simpler setup. The width is narrower at 1.34 inches, allowing it to fit into tighter electrical spaces than the 2PM. It does not include power metering, so you cannot track energy usage. This is a practical choice if you only need to automate one circuit and want a compact, hub-free relay that fits in small junction boxes.
THIRDREALITY Zigbee No-Wiring Smart Switch
The THIRDREALITY Zigbee No-Wiring Smart Switch replaces your existing wall rocker rather than installing inside the box. It is a single-channel device, so you lose the dual-circuit capability of the Shelly 2PM. It requires a hub, specifically noting compatibility with SmartThings and Home Assistant. The size is significantly larger at 4.72 inches tall, designed to cover the faceplate of your current switch. It offers no power metering. This option is best for renters or those who want to add smart control to existing switches without touching any wiring or electrical boxes.
Shelly 1PM Gen4 Relay Switch with Power Metering
The Shelly 1PM Gen4 offers single-channel control instead of the dual channels in the 2PM. It retains the built-in power metering, allowing you to track energy consumption for one appliance. Like the original, it operates without a hub and supports Matter, though it connects via Zigbee. The dimensions are identical at 1.65 inches wide and 0.63 inches deep. It is a direct alternative if you only need to monitor and control one circuit. This model is ideal for users who want the same monitoring features but do not need the second channel for a separate light or device.
Shelly 1PM Mini Gen4 Smart Relay Switch
The Shelly 1PM Mini Gen4 is a compact, single-channel relay that sacrifices the dual-circuit capacity of the 2PM. It includes power metering for precise energy tracking of one appliance. The device is smaller, measuring 1.34 inches wide, making it suitable for very tight spaces. It connects via Zigbee and supports Matter, operating without a hub. It lacks the higher 16A load capacity per channel, focusing instead on smaller loads. This is a good fit if you need to monitor a single low-power device and have limited space in your electrical box for the hardware.
