FritzBox TR-064: Enable/Disable WAN Connection

Hi everyone, I’m currently working on a project where I need to control the WAN connection of my FritzBox router using TR-064. The goal is to toggle between the primary WAN (LTE) and a backup LAN connection to another FritzBox. I’ve been researching how to achieve this, but I’m not entirely sure about the best approach. Has anyone here successfully implemented such a setup? I’m particularly interested in whether it’s possible to send commands via TR-064 to enable or disable the WAN connection programmatically. Any insights or resources you could share would be greatly appreciated! Let’s collaborate to find a solution. :slight_smile:
