Background

• The Activity Hub’s replacement Wi-Fi card only operates on a 2.4GHz network.
• It cannot operate on a 5GHz network.
• If the home’s Wi-Fi is exclusively 5GHz, the Wi-Fi card replacement will not function properly.

Testing the Network Frequency

1. Connect to the home’s Wi-Fi network using a device or laptop.
2. Run a Wi-Fi test (search online for “Wi-Fi test” tools) to check signal strength and confirm the network frequency.

Zemplee Hub Wi-Fi Card Details

• The Zemplee Hub is originally equipped with a “Device Link” card (RE926RX).
• This card is not needed if you are replacing it with the new 2.4GHz Wi-Fi card (RE926RS).
• Once the new Wi-Fi card is installed, data will only transmit through the Wi-Fi network. If the Wi-Fi network fails, the hub will attempt to connect to LTE.

Connection priority order:

1. Wi-Fi / Ethernet
2. LTE

Alternate Solutions Before the Home Visit

If the home’s network is not 2.4GHz (and thus the Wi-Fi card replacement is not possible), consider the following:

Hard Reset of the Existing Hub

• Refer to the “Hard Reset” section for detailed information 

Change the Position of the Existing Hub

• Relocate the Hub to a different spot in the home to see if LTE signal strength improves.

Replace the Hub with a New One

• Some replacement Hubs may connect more reliably to the local LTE network.
• Call Zemplee Support (1-888-508-5908) to inform them you are using a new hub due to connectivity issues.
• Provide the Member/Client name, Client ID#, and the new hub’s MAC ID.
• Keep the new hub powered on continuously so sensors can be transferred to it.

Note: These alternate solutions do not guarantee consistent data transmission but may help improve connectivity if 2.4GHz Wi-Fi is unavailable.

LTE → Wi-Fi Replacement Process

Remove the Hub’s Back Panel

• Gently depress the tab on the black back panel of the Hub to remove it.

Remove the “Device Link” Card

• Carefully pull at the four edges of the RE926RX card to remove it.

Insert the New Wi-Fi Card

• Align the connection ports on the board with those on the RE926RS Wi-Fi card.
• Ensure the card is seated evenly and securely in the slot.

Power On the Hub

• Allow the Hub to connect to LTE first.
• The second LED light from the bottom on the panel will glow solid green once LTE connection is established.

Contact Zemplee Support (1-888-508-5908)

• Inform the agent that the Hub needs to be switched to Wi-Fi.
• Provide the following information:
  • Member/Client name
  • Client ID#
  • MAC ID of the Alula Hub
  • Wi-Fi network name (SSID)
  • Wi-Fi password

Wait for Wi-Fi Switch

• Remain on the call for approximately 5 minutes.
• Zemplee Support will confirm once the Hub has switched from LTE to Wi-Fi.

Proceed with Further Installations

• If additional devices need to be installed or replaced, or if this is a new installation, continue with the normal setup process once Wi-Fi connectivity is confirmed.
