Connectivity and Smart Features

connectivity options

Edge: Shelly 1PM Mini Gen4 Smart Relay Switch

The Shelly 1PM Mini Gen4 offers a broader range of connection protocols. It supports Wi-Fi, Zigbee, and Matter. This allows you to integrate the device into various smart home ecosystems without needing separate bridges for each protocol. The Shelly 1L relies solely on Wi-Fi. While this is sufficient for many users, it lacks the native Zigbee and Matter support found in the Mini Gen4. If you use a hub-based system or want future-proofing with Matter, the Mini Gen4 is the stronger choice. The 1L is simpler but less versatile in terms of network integration.

power monitoring

Edge: Shelly 1PM Mini Gen4 Smart Relay Switch

Power tracking is a key differentiator between these two devices. The Shelly 1PM Mini Gen4 includes precise power monitoring capabilities. You can view real-time and historical data to track energy usage for appliances up to 8A. This helps you identify inefficient devices and manage consumption. The Shelly 1L does not list any power monitoring features in its specifications. It functions as a basic relay switch. If you need to know how much electricity a light or appliance is drawing, the Mini Gen4 provides that data. The 1L offers no such insight.

wiring requirements

Edge: Shelly 1L No-Neutral Relay Switch

Installation wiring differs significantly between the two models. The Shelly 1L is designed for no-neutral installations. It requires only a live wire, making it ideal for retrofitting behind existing wall switches where a neutral wire is absent. The Shelly 1PM Mini Gen4 specifications do not explicitly state no-neutral capability. It is generally intended for installation behind sockets or inside appliance casings where wiring may differ. If you are upgrading a standard wall switch without a neutral wire, the 1L is the practical solution. The Mini Gen4 may require a neutral connection depending on the setup.

size and form factor

Edge: Shelly 1PM Mini Gen4 Smart Relay Switch

Physical dimensions affect where you can place these devices. The Shelly 1L measures 1.42 inches in width, 1.61 inches in height, and 0.67 inches in length. It weighs 1.41 ounces. The Shelly 1PM Mini Gen4 is more compact, measuring 1.34 inches wide, 1.14 inches high, and 0.63 inches long. It weighs only 0.71 ounces. The Mini Gen4 is smaller and lighter, which helps when fitting into tight spaces like small switch boxes or appliance interiors. The 1L is slightly bulkier, which might be a constraint in very cramped electrical boxes.

memory and processor

Edge: Shelly 1PM Mini Gen4 Smart Relay Switch

Internal hardware specs influence performance and local automation. The Shelly 1PM Mini Gen4 features an upgraded processor and 8 MB of memory. This ensures fast, efficient performance and supports more complex local scenes and automations. The Shelly 1L specifications do not list processor speed or memory capacity. It functions as a standard relay switch without highlighted advanced local processing capabilities. For users who rely on local execution of commands to ensure reliability during internet outages, the Mini Gen4’s hardware specs suggest better performance. The 1L lacks this detailed technical transparency.

smart home compatibility

Edge: Shelly 1PM Mini Gen4 Smart Relay Switch

Both devices work with major voice assistants and platforms. The Shelly 1L is compatible with Amazon Alexa and Google Home. It also supports Android and iOS control via Wi-Fi. The Shelly 1PM Mini Gen4 is compatible with Matter, which is a universal standard for smart home devices. It also supports Wi-Fi and Zigbee. While the 1L works with Alexa and Google, the Mini Gen4’s Matter support offers broader interoperability with other brands and systems. If you want seamless integration with a wide range of devices, the Mini Gen4 has the advantage. The 1L is limited to standard Wi-Fi based assistants.
