Shelly 1PM Mini vs 1 Gen4 Specs
Maximum Load
The Shelly 1 Gen4 Smart Relay Switch handles up to 16A of current. This higher capacity allows you to control heavier loads, such as larger lighting circuits or more powerful appliances, without overloading the device. In contrast, the Shelly 1PM Mini Gen4 Smart Relay Switch is rated for a maximum of 8A. This lower limit is sufficient for smaller devices like fans or kitchen gadgets, but it restricts what you can connect to it. If you need to manage high-power equipment, the 16A rating of the 1 Gen4 provides a wider margin of safety and versatility. The 1PM Mini is better suited for lighter duties.
Connectivity
Both devices support Wi-Fi, Zigbee, and Matter protocols, ensuring broad smart home integration without requiring a separate hub. However, the Shelly 1 Gen4 Smart Relay Switch also includes Bluetooth connectivity. This additional feature allows for local setup and control via your phone when you are near the device, which can be useful during initial configuration or if your Wi-Fi network is unstable. The Shelly 1PM Mini Gen4 Smart Relay Switch lists Wi-Fi, Zigbee, and Matter compatibility but does not mention Bluetooth in its specifications. For users who value local wireless options beyond Wi-Fi, the 1 Gen4 offers a more complete wireless suite.
Power Monitoring
The Shelly 1PM Mini Gen4 Smart Relay Switch includes precise power monitoring capabilities. This feature allows you to track real-time energy consumption and view historical data for the appliances connected to it. You can use this information to manage energy use and identify inefficient devices. The product title and features explicitly highlight this energy tracking functionality. The Shelly 1 Gen4 Smart Relay Switch is described as a relay switch with dry contacts, but its specifications do not list power monitoring. If you need to measure electricity usage for your connected devices, the 1PM Mini provides this data, while the 1 Gen4 focuses on simple switching.
Physical Dimensions
Size matters when fitting these relays into tight spaces like wall boxes or behind sockets. The Shelly 1PM Mini Gen4 Smart Relay Switch measures 1.34 inches in width and 1.14 inches in height. The Shelly 1 Gen4 Smart Relay Switch is slightly larger, measuring 1.65 inches in width and 1.46 inches in height. Both share the same length of 0.63 inches. The 1PM Mini’s more compact footprint makes it easier to install in confined areas where space is limited. The 1 Gen4 is still small, but the 1PM Mini offers a slight advantage for installations in very tight enclosures.
Switch Function
The Shelly 1 Gen4 Smart Relay Switch features dry contacts. This specific type of output allows it to interface with external systems, such as garage door openers or other equipment that requires a simple closure signal rather than switching mains power directly. This makes it versatile for automating non-lighting devices. The Shelly 1PM Mini Gen4 Smart Relay Switch is described as a smart switch for appliances but does not specify dry contacts in its features. It is designed to switch the load directly. If your automation project requires dry contact outputs for interfacing with other hardware, the 1 Gen4 is the more capable choice.
