Wi-Fi Control & App Troubleshooting

Applies to: COCBH Smart Hub · CR Wireless Repeater · iZone Home app · iZone Worldwide

iZone app cannot find the system​

The iZone Home app does not discover the system after opening.

Steps to resolve:

  1. Ensure the phone is connected to the same 2.4GHz Wi-Fi network as the Smart Hub
  2. Disable any VPN on the phone during setup and normal use
  3. Force-close and reopen the iZone app
  4. If the hub was recently factory reset, complete the commissioning process via + Add System in the app

App shows system as offline​

The iZone app shows the system as offline or unreachable.

Steps to resolve:

  1. Check the Smart Hub's LED status — a solid green indicates normal operation
  2. Confirm the router has an active internet connection
  3. Power cycle the Smart Hub: unplug it for 10 seconds and plug it back in
  4. Check the router's DHCP lease table to confirm the hub has an assigned IP address
  5. If the hub is offline after a router change, factory reset the hub and recommission it to the new network

iZone Worldwide (remote access) not working​

You cannot control the system from outside the home network.

Steps to resolve:

  1. Confirm the Smart Hub has internet access — check from the local app first
  2. Ensure the iZone Worldwide service is activated in the app: Settings → iZone Worldwide → Enable
  3. Check that no firewall or ISP-level restriction is blocking outbound connections from the Smart Hub
  4. If recently changed ISP or modem, power cycle the hub after the new connection is confirmed working

iZone Recipes not triggering as expected​

Automated recipes (triggers and actions) are not running at the scheduled times or conditions.

Steps to resolve:

  1. Confirm the Smart Hub has internet access — recipes depend on cloud connectivity for time-based triggers
  2. Check the recipe conditions: App → Recipes → [Recipe Name] → Edit and verify the trigger logic
  3. Ensure the device being triggered (e.g. a light or AC zone) is online and responding to manual commands
  4. Check the phone's time zone matches the hub's — a mismatch causes schedule offset

Wireless Repeater (CR) not extending range​

Devices beyond the repeater still show as out of range or unresponsive.

Steps to resolve:

  1. Confirm the CR Repeater is powered and paired to the COCBH Smart Hub
  2. Position the repeater midway between the hub and the devices with poor connectivity — not at the edge of the existing coverage area
  3. The CR operates on 433MHz RF; ensure it is not located near sources of interference (microwave ovens, cordless phones)
  4. Re-pair the CR if it was recently moved: press and hold the pair button, then pair via Devices → Wireless Repeater in the iZone app
