On my CerboGX I have installed some Alexa nodes in node-red to control the two relays of the cerbo. Unfortunately I can't get them to work, I can't link my account correctly. Now I wanted to uninstall and reinstall them to try from scratch but node-red doesn't let me uninstall them, it reports me an error. I thought about resetting node red, does anyone know how I can do to have a fresh installation?
