IY-HUB2: Setting Up Your Relay Module

Applies to: IY-HUB2 with Relay Module add-on.

This comprehensive guide walks you through the entire hardware and software setup for your Insytly Relay Module. Follow these steps to connect the relay, wire your equipment, and configure it for remote control via the Insytly platform.

Before You Begin: Safety & Preparation

• ⚠️ Disconnect All Power: Before starting, completely disconnect the power source for both your IY-HUB2 and the equipment you intend to control.

• Check Your Equipment: Inspect the Relay Module, cables, and your external equipment for any signs of damage before installation.

• Verify Ratings: The Insytly Relay Module is for low-voltage DC loads only. Do NOT connect mains voltage (e.g., 230V AC). Check the relay's specifications for its maximum voltage and current ratings.

Part 1: Connecting the Relay Module to the IY-HUB2

First, let's connect the relay board to the main unit.

1. Locate the Relay Port: On your IY-HUB2's main wiring loom, identify the dedicated Relay Module Cable connector (a 4-core cable, labelled as item 17 in the product guide and has a white label of "Relay" on the  loom itself). 

2. Connect the Cable: Securely plug one end of the provided cable into the IY-HUB2's relay port and the other end into the port on the Relay Module board (this end is typically already plugged into the relay).

Part 2: Wiring Your Equipment to the Relay

Now, let's wire your external device (e.g., a light, siren, or router) to a channel on the relay board.

Understanding the Relay Terminals

Each channel on the relay has three screw terminals:

• COM (Common): The input power for the circuit.

• NO (Normally Open): The circuit is OFF by default. It connects to COM when the relay is activated. This is used for most On/Off applications.

• NC (Normally Closed): The circuit is ON by default. It disconnects from COM when the relay is activated. This is used for Remote Reset applications. 

Wiring Example A: Standard On/Off Control

Use this method to turn a device on or off remotely. 

The circuit is "open" by default, and activating the relay closes the circuit to turn your device "On".

1. Connect the Positive (+) from your power source to the COM terminal.
2.  Connect the NO terminal to the Positive (+) input of your equipment. 
3. Connect the Negative (-) input of your equipment directly to the Negative (-) of your power source (common ground).

[12V+ Power Source] ----> [COM]
[NO] ----> [+ Your Equipment -] ----> [12V- Power Source]
[Relay Channel]       [NC]

Result: When you turn the relay "On" in the Insytly platform (via the added component in the device dashboard), the connection between COM and NO is made, and your equipment (e.g., a light) will turn on.

Best Use Cases:

• Turning on/off lights or sirens.

• Activating pumps or other machinery.

• Opening or closing gates or barriers.

• Any application where you need to maintain a continuous "On" or "Off" state.

Wiring Example B: Remote Reset Control

Use this method to remotely reboot a device that is normally always on (like a router). You will use the Relay Module's "3 Second Reset Mode" for this.

This involves interrupting the power supply to the device.

1. Connect the Positive (+) from your power source to the COM terminal.
2. Connect the NC terminal to the Positive (+) input of the device you want to reboot.
3. Connect the Negative (-) input of the device directly to the Negative (-) of your power source.

[12V+ Power Source] ----> [COM]
[NC] ----> [+ Your Equipment -] ----> [12V- Power Source]
[Relay Channel]       [NO]

Result: Your equipment will be on by default because COM and NC are connected. When you activate the "Reset" function in the Insytly platform (via the added component in the device dashboard), the connection between COM and NC is broken for 3 seconds, cutting power to your device and forcing it to reboot.

Best Use Cases:

• Remotely rebooting a router, modem, or other communication gear. This is the most common and valuable use case.

• Power-cycling a camera or sensor that has become unresponsive.

• Any situation where a quick "off and on again" is needed to resolve a technical issue.

Part 3: Final Verification & Dashboard Setup

1. Power Up: Once all wiring is complete and secure, reconnect the main power loom to your IY-HUB2.
2. Check Relay LEDs: When the system powers on, the small LEDs on the relay board should light up for 5 seconds and then turn off. This confirms a successful connection. 
   1. If they stay on continuously, there may be a fault; in this case please contact support.
3. Log In to the Platform: log in to your Insytly account at `app.insytly.com` and go to the device you have installed (you will need to first add the device to the platform if this has not already been completed).
4. Choose Your Mode: Locate the device settings within the device you installed and go to Remote Hardware Configuration. From here you will find the Relays tab. Within the Relays tab you will find a list of Relay 1, Relay 2, Relay 3, and Relay 4. Select one of the two options for each of the relay channels from the dropdown menu: 
   1. On/Off Control Mode: Choose this if you followed Wiring Example A. The relay will function like a standard switch.    
   2. 3 Second Reset Mode: Choose this if you followed Wiring Example B. Activating the relay will now trigger a 3-second power cycle to reboot your equipment.
      

1. Add Relay Switch to Device Dashboard: For easy access, add the relay controls to your dashboard.    
   1. Navigate to your device dashboard again.    
   2. Click the Edit Dashboard icon (spanner/wrench) in the bottom right.    
   3. Click the Add Component icon (plus symbol).    
   4. Select the Relay Switch and/or Relay Log component to add this to the dashboard (see screenshot below).   
   5. Arrange the new tiles and select to Edit Component to set up the component for the channel you just wired and would like to switch.
   6. Save your dashboard.

An example of how the final Relay Switch and Logs could look like is shown in the example below.

After clicking a relay component on the dashboard to send a command, the tile will show a "pending" status.

⚠️ Important: Best Practices for Sending Commands

•  Allow Commands to Complete: After clicking a relay tile to send a command (On, Off, or Reset), the tile will show a "pending" status. 
• Please wait for this status to clear before sending another command to the same relay channel. 
• Why This is Important: Your Insytly unit needs time to receive the command via the cellular network, execute the action, and report its new status back to the platform. Sending multiple commands in rapid succession can interrupt this process and may cause the device to become unresponsive. 
• Consequences of Misuse: If a device becomes unresponsive due to repeated, rapid command inputs, it may require a manual power cycle to recover. In rare cases, this can lead to non-recoverable faults. Please note that damage resulting from improper use may not be covered under warranty. 

Your hardware is now fully set up!
