Your Shelly Pro 4PM Web Interface: High-Power Control in Your Hands

If you are a user of a Shelly Pro 4PM (or are thinking of adding it to your home automation arsenal), you will know that it is a high-performance device designed for electrical panels and loads important. Beyond the app on your phone, the true power and Granular configuration of this device resides in its web interface.

Simply by typing their IP address into your browser (for example, http://192.168.1.70 ), you will access its command center. Here you you will tell your Shelly Pro 4PM exactly how its four relays and how they manage external inputs, plus key security and monitoring settings!

Let's see the most important settings, those that will give you a super flexible and safe control:

Shelly Pro 4PM Home Interface

1. The Button You Connect (Input Mode): What type of keystroke does it detect?

This section is essential to tell your Shelly Pro 4PM how to interpret the signals from the physical switches or buttons you have connected to its input terminals ( SW1 , SW2 , SW3 , SW4 ).

  • Switch (Toggle Switch): Shelly Pro 4PM Input Mode Switch
    • Description: Ideal for wall switches conventional ones that have two stable positions: on or off off.
    • Behavior: The Shelly will read that fixed position.
    • When to use it? To control lights, fans or any load that must remain in a constant state according to the position of the physical switch.
  • Button (Momentary Push Button): Shelly Pro 4PM Input Mode Button
    • Description: Perfect for returning push buttons to their original position when released (like a doorbell).
    • Behavior: The Shelly will detect a "pulsation" (a momentary event) each time it is pressed briefly press the button.
    • Ideal for triggering complex automations, such as of your sliding door, without complicating the wiring power!

2. What Relays Do (Output Type): How do the outputs react?

Here lies the true control power of the Shelly Pro 4PM, defining the behavior of each of its four individual relays . This is crucial for functions like your sliding door motorized, where you need precise pulses.

  • Toggle (Steady On/Off):
    • Description: This is the standard behavior of a relay.
    • Behavior: Upon receiving a "turn on" command, the relay turns on and stays on . When receive a "shut down" command, it shuts down and remains off .
    • When to use it? For general lighting, outlets, or any appliance that you want to turn on or turn off continuously.
  • Momentary (Short Pulse):
    • Description: Here's the pulse trick! It allows that the Shelly Pro 4PM acts as a momentary push button on its output.
    • Behavior: When you activate this output, the relay turns on for just an instant (you tell it how long in the "Timers" section with the "Auto OFF" function) and turns off automatically.
    • A must for your controller inputs! garage door/gate, electric locks, irrigation systems or any device that needs a quick "tap" to get active!
  • Edge (Edge Change):
    • Description: A less common mode for control direct departures.
    • Behavior: The relay changes its state (from ON to OFF or vice versa) each time the connected physical input detects a change of state.
    • When to use it? For very specific applications where you need the output to alternate its state with each detection of a transition at the entrance.
  • Detached (Detached Input):
    • Description: Free your physical switches! Completely decouples physical inputs from outputs Shelly Pro 4PM's own relay.
    • Behavior: Push buttons or switches Physicists connected to the Shelly Pro 4PM will continue to report their status or events to the Shelly app and Home Assistant, but will not directly control the internal relays of the device .
    • When to use it? Perfect for using switches physical to activate complex automations in Home Assistant (such as turning on multiple lights, activating a scene, or controlling a different device) without the Shelly Pro 4PM relays being seen locally affected.
  • Activation (Motion Sensor Activation):
    • Description: A specific mode for scenarios involving presence detection.
    • Behavior: When an input (e.g. from a motion sensor) is activated, the relay turns on. If the relay has an "Auto Off" timer, this mode ensures that the timer is reset as long as the input remains active or is reactive within time.
    • When to use it? For lights that stay on on while there is presence, or extractors that work while a sensor is active.

3. What Does It Remember When Power On: How does it act after a power outage?

This setting is vital for safety and comfort as it defines the behavior of each relay if the Shelly Pro 4PM is reset or lost and recovers nutrition.

  • Turn ON: The relay will turn on automatically when the Shelly regains power.
  • Turn OFF: The relay will automatically turn off when Shelly regains power.
  • Restore last known state: The Shelly will try to remember what state the relay was in before the outage of energy and restore it. This is the preferred option for most lights and appliances to avoid surprises!
  • Current state of the switch physical): The relay state will match the physical position of the connected switch ( SWx ) at the moment the Shelly Pro 4PM turns on.

4. Output Protections: Protecting Your Devices

This is a key section for the safety and longevity of your devices. connected. Allows you to set limits for the Shelly to cut off power If you detect a problem:

  • Overpower in watts: Sets the maximum power (in watts) that the Shelly allows to pass through by a channel. If the load exceeds this value, the Shelly will cut off the current to protect both the device and the load. Very useful for engines or heaters!
  • Overcurrent in amperes: Defines the maximum current (in amps) that can pass. If it is exceeded, the relay is disconnected to prevent overloads.
  • Overvoltage in volts: If the If the input voltage exceeds this limit, the Shelly will disconnect the relay. to protect your devices from dangerous voltage spikes.
  • Undervoltage in volts: If the input voltage falls below this value, the Shelly will disconnect the relay. Useful for protecting motors or equipment sensitive to voltage drops.
  • Enable auto recovery: If a relay is turned off due to overvoltage or undervoltage, when activating this option, the Shelly will attempt to turn it on again automatically if the abnormal condition disappears and the relay was previously on.

5. Consumption Type: For your Home Automation System

This option is specific to how Shelly reports the type of consumption to third-party systems (such as Home Assistant).

  • Description: Allows you to specify how you categorize the connected load (e.g. "light", "motor", "heater").
  • Importance: Caution! This setting does not affect the official Shelly app . Its main utility is for your external home automation system (such as Home Assistant) correctly classify and display consumption.
  • Recommendation: Consult your system's documentation home automation to know which values ​​are the most appropriate to enter here and how you will interpret them.

6. Reverse Power Measurement: If you measure backwards

In some very specific cases, due to the installation or the type of load, the direction of active power and energy measurement can appear inverted (e.g. consuming energy when it should be delivering).

  • Enable: If you enable this option, the Shelly will reverse the direction of the measurement.
  • When to use it? Only if you notice that the readings of power and energy are not logical for your circuit.

7. Lock Inputs: Freezes Physical Controls

This is a very useful safety and control feature.

  • Enable: When this option is enabled, the Shelly ignores any keystrokes or changes to its inputs physical (SW1 to SW4), regardless of the mode they are in configured.
  • When to use it? Ideal for:
    • Cleaning: Avoid accidental on/off while cleaning a switch.
    • Children: Prevent young children from activating certain circuits.
    • Maintenance: Make sure that the lights or appliances are not turned on while working on them.
    • Vacation Mode: Disable controls manuals when no one is home.
  • Important: You can only control the Shelly through from the app, the web interface or Home Assistant (if you have not unlinked the entry with "Detached").

8. Reset Counters: Reset your Stats to Zero
