Shelly 1PM Mini WiFi Smart Switch with Power Metering Setup Guide

Shelly 1PM Mini WiFi Smart Switch with Power Metering

  • Tools required:
    • Small flathead and Phillips screwdrivers
    • Wire stripper and cutter
    • Multimeter to verify voltage and continuity
    • Insulated gloves and an insulated screwdriver if working on live mains
    • Marker or label tape for identifying wires
    • Small junction box or space behind switch for the mini module
  • Applications:
    • Shelly mobile app (Shelly Cloud / Shelly App) for device discovery, initial setup and firmware updates
    • Access to a Wi‑Fi 2.4 GHz network (SSID and password) for device connection
    • Optional: local home automation controller or app for integration (compatibility not specified)

Setup steps (follow in order). Important safety note: this device is intended for installation into household electrical circuits. If the installation involves mains voltage (for example ~230 V AC), the wiring and final connection must be carried out by a trained electrician. Always isolate power at the consumer unit and verify circuits are dead before touching conductors.

  • Read the device label and documentation: Confirm the unit you have is the Shelly 1PM Mini and note its terminal markings (typically L, N, O or similar). Review the manufacturer quick start for any model-specific warnings.
  • Prepare the installation location: Ensure there is sufficient space behind the target switch or inside the junction box for the mini module. Turn off and lock out the relevant circuit at the consumer unit.
  • Verify power is off: Use a multimeter or a verified voltage tester to confirm the circuit is de-energised. Do not proceed if voltage is present.
  • Identify conductors: Identify the live (supply) and neutral conductors for the load you will control. If you are unsure which wire is which, do not guess — contact a qualified electrician. Label wires for reassembly.
  • Make the wiring connections:
    • Connect the supply live to the module terminal marked for line (L) as instructed by Shelly documentation.
    • Connect the supply neutral to the module neutral terminal (N) if the module requires neutral for metering and operation.
    • Connect the switched live/load conductor to the module output terminal (often O or similar).
    • Ensure all terminal screws are tightened securely and that no bare conductor is exposed outside the terminal.
  • Mount the module: Place the Shelly 1PM Mini inside the available space or a small junction box ensuring it will not be stressed by wiring when the switch is mounted back. Do not trap wires under sharp edges.
  • Restore power and initial checks: Reconnect the circuit at the consumer unit. Observe the device indicators (LEDs) to confirm it has power. If any abnormal smell, smoke, or heating occurs, isolate the circuit immediately and consult a qualified electrician.
  • Connect to Wi‑Fi via the Shelly app:
    • Install the Shelly mobile app on your phone/tablet.
    • Open the app and follow the manufacturer flow to add a new device. The Shelly 1PM Mini will usually start in access-point (AP) mode or be discoverable by the app when powered.
    • When prompted, join the device's temporary Wi‑Fi network in your phone Wi‑Fi settings, then complete configuration in the app by entering your 2.4 GHz Wi‑Fi SSID and password.
    • Wait for the device to connect to your network; the app should report online status.
  • Verify switching and metering:
    • Use the app to toggle the relay on and off and confirm the controlled load responds correctly.
    • Check the power metering readout in the app to confirm it displays real-time consumption. Allow a small load to run to see stable measurements.
  • Configure device settings:
    • In the app, set device name, location and any scheduling or rules you require.
    • Check for and install any firmware updates presented by the Shelly app to ensure up-to-date behaviour and security.
    • If integrating with a home automation system, follow that controller's instructions to add the Shelly device (integration method and compatibility not specified here).
  • Final installation checks:
    • Securely refit the wall switch or close the junction box cover, ensuring no wires are pinched.
    • Confirm normal operation after the enclosure is closed and that there is adequate ventilation around the module.

Troubleshooting and notes: if the device fails to appear in the app, reboot the module by isolating and restoring power; confirm your phone is on the 2.4 GHz band, not 5 GHz. If measurements read zero with a known load, re-check wiring and terminal tightening. For any uncertain wiring, abnormal behaviour or if the installation requires modifications to fixed wiring, use a trained electrician.
