Professional DIN-rail relay for residential

Shelly Pro 1 is a one-phase, single-channel relay rated at 16 A that mounts on standard DIN rail inside a breaker box. It provides dry-contact switching for a wide range of AC loads and appliances. The unit is designed for installers and facility managers who need reliable, hub-free control of lighting and power circuits.

Connectivity limited to LAN.

The relay communicates through wired Ethernet, Wi-Fi and Bluetooth simultaneously, using LAN as a high-reliability primary link and Wi-Fi as a backup. All cloud and local integrations are secured with TLS 1.2 encryption. No other wireless protocols or hub dependencies are supported, so environments requiring Thread, Zigbee or Z-Wave cannot use this device directly.

Replaces basic contactors

It upgrades installations where manual switching or simple time clocks are currently used, adding remote control, advanced scheduling and mjS scripting for custom logic. The jump is worth it when you need dry-contact flexibility across mixed voltages and want to manage circuits from a phone or voice assistant without adding a separate gateway.

Highlights

  • DIN rail mounting fits standard breaker boxes
  • Dry contacts enable control of varied voltage loads
  • LAN, Wi-Fi and Bluetooth provide simultaneous connectivity
  • TLS 1.2 encryption secures cloud and local links

Questions about this item

Should I pick the 16 A version for my lighting circuits?

The single channel is rated at 16 A, which covers most residential lighting and small-appliance loads.

What does the 16 A rating mean once the relay is installed in a breaker box?

It indicates the maximum continuous current the dry contact can switch, so you can control one circuit up to that limit.

How does the LAN connection cap the control speed compared with Wi-Fi?

LAN provides a wired link for high security and reliability, while Wi-Fi and Bluetooth run simultaneously as backup.
