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.

- The internet connection is down, the router is having problems, or network settings are preventing internet access.

- 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

- This usually happens when a firewall, network restriction, login page, or incorrect device time is preventing secure internet connections.

- 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.

- 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- This usually happens when the device's login credentials are no longer valid or have been changed.

- This usually happens when the device is new, has been reset, or its configuration has not yet been completed.
