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.
For further information please check our Firmware Page
Thank you in advance
