Hello Roland, You don't need to add your ctrlX CORE to ctrlX WORKS, there is not really added value for you. The point I wanted to make with the use of ctrlX WORKS is the possibility to create and use the virtual control ctrlX CORE virtual. Because with the ctrlX CORE virtual you don't need licenses and therefore can test apps right away. See this guide on how to set up a ctrlX CORE virtual. What I see from your screenshot is, that you are still using a version prior to 1.12 (RM21.11) at your ctrlX CORE. Which Version of Node-RED are you using here? I think it would be best for you to update your ctrlX CORE to V 1.12 and install Node-RED in the same version 1.12 there. Then you need the support of your mentor to get the license to the ctrlX CORE. Hint: In the Collaboration Room (path: ctrlX_CORE_APPS/All-Apps-In-One-File/RM21.11 - V 1.12) you can find the SystemImage and a Guideline on how to perform the update in the Release Notes. Best regards, Nick
