Set up your eco-system
Pair your products. Get them working together.
Follow this guide to pair your myenergi products, choose the correct Load Controller and Gateway Device, and check your products are communicating.
Coordinates the eco-system. Every other product pairs with it.
Handles external communication. It can be the Load Controller or a different compatible product.
Radio needs matching channels. Network pairing needs compatible products on the same local network.
Your pairing assistant
Build your steps.
Pick the product you are setting up. This guide helps you work through the steps. It does not connect to or change your products.
Use Wi-Fi or Ethernet where supported. Older products may need radio.
The guide changes the controller instructions to match.
Step 1 · Before you pair
Prepare the connection
Connect both products to the same local network, using Wi-Fi or Ethernet where supported. Network pairing is not available on every model.
If your product needs radio, choose Radio above. Radio Pairing is off by default on current firmware and must be enabled where required.
Steps checked
You have worked through the guide.
Confirm the product and its serial number appear correctly on the Load Controller. Completing this checklist does not verify the connection remotely.
Know which product does what
Two jobs. They do not have to be on the same product.
Load Controller
Coordinates the linked products. Choose it first, then pair other products to it. A Load Controller does not have to have a built-in gateway.
Secondary Device
A product joining the existing eco-system follows the Load Controller. Do not set it up as a second Load Controller.
Gateway Device
Handles communication outside the eco-system. Use only one. It may be the Load Controller, another compatible product or a separate hub.
My menu uses older names
| Current name | Older name or menu |
|---|---|
| Load Controller | Master / Set Master |
| Secondary Device | Slave / Set Master not selected |
| Gateway Device | vHub Device / Set vHub, or a separate hub |
The screenshots and videos below may show these older menu names.
Before pairing
Radio and Wi-Fi are different connections.
Radio pairing
Products communicate directly by radio. Match the radio channel to the existing Load Controller, and check that Radio Pairing is enabled where the setting is available.
Current firmware has radio pairing off by default as part of the RED-related changes. Older menus may not show this setting.
Network pairing
Compatible products must be on the same local network. Use supported Wi-Fi or Ethernet connections. Being registered in the same app account is not the same as being paired.
Wi-Fi products need a suitable 2.4 GHz network. Network pairing is not a substitute for radio on harvi or a legacy hub. zappi 2.0 uses radio for eco-system pairing.
Changing it may affect the hierarchy and shared settings. Remove only the product you need to re-pair, rather than resetting the whole eco-system.

zappi 2.0, zappi 2.1, eddi and libbi
-
Choose the Load Controller.
On that product, open Installer Settings, then Linked Devices and Role. Select Load Controller. On older menus, use Set Master.
-
Set the joining product as Secondary Device.
Open Linked Devices and Role. Select Secondary Device and make sure Load Controller is not selected. On older menus, Set Master should not be ticked.
-
Start pairing on the Secondary Device.
Go to Linked Devices, then Pairing Mode.
-
Find it on the Load Controller.
Open Linked Devices and Pairing Mode on the controller where required. Check the serial number, select the correct product and accept with the tick or plus button.
-
Wait for pairing to finish.
Allow the countdown or updating message to complete. Check that the product remains in Linked Devices without a question mark or communication warning.
If the controller is a zappi GLO, use Installer Assistant for the controller side of the process. Menu paths vary with model and firmware.

zappi GLO: create or join an eco-system
Use the Installer Assistant app for commissioning and eco-system setup. You need access to the existing products when joining an eco-system.
First product on a new site
-
From Installation Details, open Ecosystem.
-
Choose Create New Ecosystem.
-
zappi GLO assigns itself as Controller and Gateway Device. Confirm these roles in the app.
Add to an existing eco-system
-
From Installation Details, open Ecosystem.
-
Choose Join Ecosystem. Pairing mode is available for up to 10 minutes.
-
Follow the app prompts and choose Pair with Controller Device.
-
Confirm the new zappi GLO joins as a Secondary Device.
Make sure the existing zappi GLO is already commissioned, then use the joining flow on the new one. Some screens use “Search for Primary”. Keep the existing Load Controller and follow the app prompts. The eco-system must still have only one controller and one gateway.
Bluetooth connects your phone to zappi GLO during setup. It does not replace the radio or network link between products. Follow the app if a restart is requested.
Watch the zappi GLO pairing video
harvi: pair the wireless CT sensor
-
Prepare the controller’s radio connection.
Use the same radio channel. Enable Radio Pairing on the controller if required. harvi does not join your home Wi-Fi.
-
Briefly press harvi’s Pair button for about one second.
Count the blue flashes. One flash means channel 1, two means channel 2, and so on. Match the existing controller’s channel, rather than changing an established site to channel 1.
-
Look for red flashes.
This shows harvi is in pairing mode. On a controller with a display, open Linked Devices and Pairing Mode. Select the matching harvi serial number and press the tick or plus button.
-
Wait for confirmation.
Allow the countdown to finish and check that the question mark disappears. If your controller is zappi GLO, complete the controller side through Installer Assistant.
-
Check the CT configuration.
The installer must confirm harvi’s CT functions and phase settings match the installation. Pairing alone does not configure these. For a replacement, record the old settings before removing it.
hub: pair a separate gateway
-
Check the gateway arrangement first.
There must be only one active gateway. If the eco-system already uses a built-in gateway, confirm the intended setup before adding a separate hub.
-
Match the radio channel.
The hub’s internet connection is separate from its radio link to the Load Controller. Enable radio pairing on the controller if required.
-
Briefly press hub’s Pair button.
On the Load Controller, open Linked Devices and Pairing Mode where required.
-
Check the serial number and accept.
Press the tick or plus button on a screen-based controller, then wait for the link to appear. Use Installer Assistant for a zappi GLO controller.
Re-pair or replace an existing product
-
Record the current product roles and any relevant settings, especially harvi CT configuration.
-
On the Load Controller, open Installer Settings and enter your installer passcode.
-
Open Linked Devices, then Devices.
-
Select the old entry for the product being re-paired or replaced, then choose Remove Device.
-
Follow the pairing instructions for the new or re-paired product.
For a zappi GLO controller, manage the linked eco-system in Installer Assistant. Replacing the Load Controller itself is a different change. Ask for guidance before rebuilding the hierarchy.
Make sense of the light
Count harvi’s blue flashes.
The number of flashes identifies the radio channel. Red flashes afterwards mean it is in pairing mode.
Check the existing Load Controller’s channel first. Default channel 1 is not a reason to change an already working eco-system.
1 blue flash, then red pairing mode.
An illustration, not a live reading from your harvi. It does not change its channel.
Before you finish
Check the result on the products.
A completed countdown is only part of the check. Confirm the right product is linked and communicating.
A local link can be working while the app is offline. Check the gateway’s internet connection separately if the products are paired but not visible online.
If it does not work
Start with the symptom.
The product does not appear during pairing
Check that you selected the right connection method. For radio, match channels and enable Radio Pairing where required. For supported network pairing, put both products on the same local network. Make sure you are pairing to the Load Controller and have started pairing mode on the joining product.
For radio, move closer where practical and check for walls or metal blocking the signal. If pairing mode expires, start it again.
A question mark remains beside the product
Wait for the countdown and updating message to finish. If it remains, check the communication link, radio channel or network connection. When re-pairing, remove the old product entry from the Load Controller before starting again.
There are two controllers or two gateways
Stop and confirm which product should hold each role. A product joining an existing eco-system should not create a second Load Controller or gateway. Keep the original controller where possible. For zappi GLO, use Join Ecosystem for an addition rather than creating a new eco-system.
I cannot find the menu shown in a screenshot
Older firmware may show Advanced instead of Installer Settings, Set Master instead of Load Controller, or Set vHub instead of Gateway Device. Use your own installer passcode. A screenshot showing 0000 is an example, not confirmation of your code.
Installer Assistant cannot connect to zappi GLO
Use Installer Assistant for commissioning and eco-system changes. Stand near the unit and check the phone’s Bluetooth permissions. Follow the current connection instructions, including the setup window after power-up.
The products are paired, but the app is offline
Check the Gateway Device and its internet connection. A radio connection between products does not itself provide an internet connection. Keep only one gateway active in the eco-system.
harvi is paired, but readings are missing or incorrect
Ask the installer to verify harvi’s CT functions and phase settings against the installation. Pairing does not automatically assign each CT’s purpose. Do not change CT settings at random to clear a warning.
