Box blink sequence - Connection debugging

By Marc_adm · 3 November 2026

This sequence description mentioned below is for ZenseHome boxes with ZBcore-version - 0.2.15 and newer, firmware-version - 7028 and newer.
You can check the ZBcore-version and firmware-version in the app in Settings --> Status --> ZenseHome Box and a list of information will be shown where you will be able to identify the versions.

If your box does not have the ZBcore-version or firmware-version as described, please contact support@zensehome.com to get your box updated to the newest version.

Check the red light seen through small window in the front of the box.
The red LED will show a sequence and will be on for 0.5 seconds and off for 0.5 seconds.
The blink sequence is repeated with a 2 second gap.

Solid on

Solid light means that the box is online and that the box is registered with an owner.

1 blink

  • Indicates that the box is not currently communicating with the controller.
  • This happens if the controllor is not currently on, the application is not running or that the communication connection between the devices has been interrupted.

3 blinks

  • The box is not connected to the network, and is currently offline.
  • The network cable is disconnected, the Wi‑Fi connection is unavailable, or the device is unable to obtain network settings.
    • Click here for connecting internet instructions if needed.

4 blinks

  • The network connection is working, but internet access is unavailable.
  • The internet connection is down, the router is having problems, or network settings are preventing internet access.

5 blinks 

  • The box has a network and internet connection, but it cannot find the online services it needs.
  • This usually happens when the network's name lookup service (DNS) is unavailable or not working correctly.

6 blinks 

  • The box can reach the internet, but it cannot establish a secure connection to the online service it needs.
  • This usually happens when a firewall, network restriction, login page, or incorrect device time is preventing secure internet connections.

7 blinks 

  • The box is online, but communication with the cloud service is currently unavailable.
  • This usually happens when the cloud service is temporarily unavailable, network security settings are blocking access, or there is a connectivity issue between the device and the cloud service.

8 blinks 

  • The box can reach the cloud service, but it was not able to sign in.
  • This usually happens when the device's login credentials are no longer valid or have been changed.

9 blinks 

  • The box has not been setup yet, so it is missing the information needed to operate.
  • This usually happens when the device is new, has been reset, or its configuration has not yet been completed.
