Hello,
In Unit 6 of Learn ESP32 with Arduino, when importing the script in Node_red (found in https://raw.githubusercontent.com/RuiSantosdotme/ESP32-Course/master/code/ESP32_NodeRED/ESP32_NodeRED_Flow.txt) I get some errors “This node is a type unknown to your installation of Node-RED.” for ui_chart and ui_switch. I tried installing node red again on a different PI.. but same error. What am I missing?
Thanks for your help
