Pairing Devices

Terminology Update

In line with best practice and inclusivity, we have updated the terminology used throughout our system interfaces and support documentation:

  • Load Controller (formerly Master)
  • Secondary Device (formerly Slave)
  • Gateway Device (formerly vHub Device) – Please note that a Load Controller does not necessarily need to be a vHub-enabled unit.

When setting up a myenergi eco-system, it is essential to pair devices correctly. The system always includes a primary Load Controller (master).

This article outlines the correct pairing procedure for each device type, including guidance on re-pairing. If re-pairing a device, you must first remove it from the Load Controller (master)'s linked device list before initiating a new pairing attempt.

zappi 2.0, zappi 2.1, eddi, libbi

The pairing process for our screen-based devices (zappi, eddi, libbi) is largely the same, although menu names may vary slightly. Begin by identifying the device to act as the Load Controller (master).

NOTE: If you are pairing to a zappi GLO, please see the zappi GLO section. 

  • On the chosen Load Controller (master), go to Installer Settings (formerly "Advanced").
  • Navigate to Linked Devices > Role.
  • Ensure Load Controller (master) is ticked.

On each Secondary Device (slave):

  • Navigate to Linked Devices > Role.
  • Ensure Secondary Device (slave) is selected and Load Controller (master) is unticked.

To initiate pairing:

  • On the Secondary Device (slave), navigate to Linked Devices > Pairing Mode.

  • Switch to the Load Controller (master) and accept the pairing request by pressing plus / tick. 

harvi

To pair a harvi device:

  • Press the physical Pair button for one second.
  • Count the number of blue LED flashes. Each flash corresponds to a channel (use channel 1 unless advised otherwise).
  • When the LED flashes red, switch to the Load Controller (master).
  • Press the tick or plus button to accept the pairing request.

Pairing is complete once the countdown timer reaches zero and the question mark icon disappears.

hub

To pair the hub device:

  • Briefly press the Pair button on the hub.
  • Switch to the Load Controller (master) device.
  • Press the tick or plus button to confirm pairing.

The pairing completes when the timer reaches zero and the question mark disappears from the screen.

Repairing into an existing system

To re-pair a device, it must first be removed from the Load Controller (master)'s linked device list:

  • On the Load Controller (master), go to Installer Settings (formerly "Advanced").
  • Enter the Installer Passcode.
  • Navigate to Linked Devices > Devices.
  • Select the device in question and choose Remove Device.

Once removed, follow the appropriate pairing process again as outlined above.

Connecting with zappi GLO

When pairing and creating an ecosystem for zappi GLO, you will need to use the Installer Assistant App. 

If zappi GLO is the first myenergi product on site

  1. From the Installation Details menu, tap Ecosystem.
  2. Tap Create New Ecosystem.
  3. Once confirmed, zappi GLO will automatically assign itself as the Controller and Gateway Device.

If zappi GLO is being added to an existing myenergi setup

Important

You will need access to the existing device(s) to complete this process.

  1. From the Installation Details menu, tap Ecosystem.

  2. Select Join Ecosystem.

  3. Your zappi GLO will now enter pairing mode and begin channel hopping for up to 10 minutes.

  4. Follow the on-screen instructions and choose Pair with Controller Device when prompted.

  5. Once pairing is complete, the zappi GLO will be added as a Secondary Device.

If pairing to an existing zappi GLO

  1. Make sure the existing zappi GLO is fully commissioned before starting.

     

  2. On the new device you want to pair, enter pairing mode by selecting Search for Primary or Search for Master.

     

  3. While the new device is in pairing mode, power off and then power on the zappi GLO.

  4. When it restarts, the zappi GLO will automatically detect and pair with the new device, assigning itself as the Controller.

eco-system Pairing Golden Rules

When pairing devices into an ecosystem, it's important to follow the rules below to ensure a successful setup and avoid any disruption to existing settings or data:

  • All devices must use the same radio channels.
    Before starting the pairing process, double-check that all devices are configured to use the same radio channel. If the channels differ, the devices will not be able to communicate or join the same ecosystem.

  • Only one Primary (Master) device is allowed.
    The Primary device acts as the Controller for the entire ecosystem. You must not attempt to pair a second Primary device, as this will cause conflicts and prevent devices from linking correctly.

  • Only one Gateway (vHub) device is permitted.
    The Gateway handles all external communications (such as internet access). Having more than one can result in communication failures or data routing issues.

  • Keep the existing Primary (Master) device wherever possible.
    If you already have a functioning ecosystem, avoid changing the Primary device. Replacing it will reset the device hierarchy and could result in the loss of stored usage data, user settings, and historical logs. Only replace the Primary device if absolutely necessary.
