CTEK App update version 4.0.3 for iOS users and Backend patches for ANDROID users relating to CS ONE, NJORD GO & NANOGRID AIR

As part of our efforts to improve our customer experience, we recently launched an updated version of our CTEK App (initially Version 4.0) followed by Versions 4.0.1 and 4.0.2 to offer enhanced features and usability. Unfortunately, some unexpected issues (bugs) arose from these updates, which our teams have been actively working to identify and resolve as quickly as possible. Today (12 December 2024) we have made further updates to address many of these:

Work has been completed in our backend for ANDROID users addressing the following issues:

User ID and Product visibility issues for registering new products on the CTEK App.

This is an automatic update, so provided you are on version 4.0.2 of the CTEK App then you do not need to take any further action.

For iOS users, version 4.0.3 of the CTEK app is now available now in the App Store and addresses the following CRITICAL issues:

Bug Fixes for Load Balancing

Bluetooth Stability Improvements

Schedule Visibility Improvements

Bug fixes for Visibility of Charging History

PLEASE NOTE

We do recommend NJORD GO users upgrade the product firmware to version 2.x or 3.x. to get the full functionality from the product.

Details of how to do this tethering to a Mobile Phone Wi-Fi hotspot (if no permanent Wi-Fi available) can be found on our troubleshooting page.

Statement regarding support for TLS Version 1.3 on R3.x Firmware

We want to inform you that CTEK does not support TLS version 1.3 on CHARGESTORM CONNECTED 1 and earlier models (Eva & CSR Series). This is due to the coding within Firmware R3.x We do however support TLS Version 1.3 in Firmware version R4.x

Please check your installed base before upgrading your security certificates to ensure continuity of the secured connection. If this is not checked and firmware is not compatible, there is a risk connectivity could be lost.
