Pairing Devices

Terminology Update

We have updated system and documentation terms for inclusivity:

  • Load Controller (formerly Master)
  • Secondary Device (formerly Slave)
  • Gateway Device (formerly vHub Device). A Load Controller does not have to be vHub-enabled.

Important – RED Directive

Radio pairing is now off by default to comply with the RED Directive. To enable it:

  • Go to Installer Settings
  • Select Communications Mode
  • Turn Radio Pairing back on if required

Unless Radio Pairing is re-enabled, all devices must be connected to the same network (for example Wi-Fi) in order to pair.

When setting up a myenergi eco-system, always start by choosing a Load Controller. All other devices must then pair with it. If re-pairing, remove the device from the Load Controller’s linked device list before starting again.

zappi 2.0, zappi 2.1, eddi, libbi

The process is the same across screen-based devices, although menu names may vary slightly.

Note: For zappi GLO, see the dedicated section below.

  • On the Load Controller, go to Installer Settings Linked Devices Role.
  • Ensure Load Controller is selected.

On each Secondary Device:

  • Go to Linked Devices Role.
  • Ensure Secondary Device is selected, and Load Controller is unticked.

To pair:

  • On the Secondary Device, go to Linked Devices Pairing Mode.
  • On the Load Controller, accept the request by pressing the tick or plus button.

harvi

  • Press the physical Pair button for one second.
  • Count the blue LED flashes to select a channel (use channel 1 unless instructed otherwise).
  • When the LED flashes red, switch to the Load Controller and accept the request.

Pairing completes once the countdown ends and the question mark icon disappears.

hub

  • Briefly press the hub’s Pair button.
  • On the Load Controller, press the tick or plus button to confirm.

Re-pairing a device

First remove it from the Load Controller’s list:

  • On the Load Controller, go to Installer Settings.
  • Enter the Installer Passcode.
  • Go to Linked Devices Devices.
  • Select the device and choose Remove Device.

Then follow the normal pairing steps above.

zappi GLO

Use the Installer Assistant App for all GLO setups.

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

Important

You need access to the existing devices to complete this process.

  1. From Installation Details, tap Ecosystem.
  2. Select Join Ecosystem.
  3. zappi GLO will enter pairing mode for up to 10 minutes.
  4. Follow on-screen steps and select Pair with Controller Device.
  5. Once complete, zappi GLO will join as a Secondary Device.
  1. Ensure the existing zappi GLO is commissioned.
  2. On the new device, enter pairing mode (Search for Primary).
  3. Power cycle the zappi GLO.
  4. It will detect and pair automatically, assigning itself as Controller.

Eco-system Pairing Golden Rules

  • All devices must use the same radio channel. Check before pairing.
  • Only one Load Controller. Do not pair a second controller.
  • Only one Gateway Device. This manages external communication.
  • Keep the same Load Controller where possible. Replacing it resets hierarchy and can clear data. Replace only if required.
  • If Radio Pairing is off, all devices must be on the same network (for example Wi-Fi). Without this, they will not be able to link.
