LAN Devices and Ethernet for Stable Local Control
Wired Shelly LAN devices give you a stable Ethernet connection in the distribution board, with channel count, load capacity, and power monitoring setting the right model.
- Single-channel switching: If you need to control a single heavy-duty circuit up to 16 A, Shelly Pro 1 provides a potential-free contact for reliable automation.
- Multi-channel control with monitoring: If your setup requires managing two circuits with consumption data, Shelly Pro 2PM offers two channels supporting up to 10 A per channel and 16 A total max.
- Three-phase energy tracking: If you are monitoring industrial power usage, Shelly Pro 3EM delivers precise three-phase energy metering over a stable LAN connection.
- Network infrastructure expansion: If you need to connect multiple DIN-rail controllers inside a distribution board, the Shelly LAN Switch expands your hardwired network directly at the distribution board.
- Motor and shutter control: If you are automating commercial blinds or gates, Shelly Pro Dual Cover / Shutter PM ensures precise positioning via a direct LAN cable connection.
Ethernet, Power and DIN-rail Checks for LAN Devices
A LAN device setup should be planned around Ethernet access, power supply and DIN-rail space.
- Ethernet port availability: Ensure your distribution board has an active LAN connection, as these professional devices rely on hardwired Ethernet for maximum stability, alongside backup Wi-Fi and Bluetooth.
- Load limits and channel capacity: Verify the amperage of your connected circuits; devices like Shelly Pro 1 handle up to 16 A, while multi-channel units like Shelly Pro 2PM are strictly limited to 10 A per channel and 16 A total.
- Potential-free contacts: Check if your application, such as an elevator or garage gate, requires dry contacts; Shelly Pro 1 and Shelly Pro 3 provide potential-free outputs for these specific commercial needs.
- Electrical phase requirements: Determine whether your facility operates on single-phase or three-phase power, which dictates whether you need a standard energy meter or a three-phase solution like Shelly Pro 3EM.
- UL certification compliance: Confirm that your building management system requires UL-certified components, as the Shelly Pro line meets these rigorous safety standards for professional installations.
Ethernet and Local Control for Shelly LAN Devices
Shelly LAN devices are built for Ethernet-based smart home connections where wired networking is preferred. They are most relevant when local control and network planning matter more than wireless-only convenience.
- Ethernet access: Check that a suitable network connection is available where the device will be installed.
- Local control: Use LAN devices when you want app and automation control through a wired network setup.
- Installation context: Review power, DIN-rail space and electrical requirements before choosing a LAN-capable device.
