I'm trying to make a simple controller based on Raspberry Pi 3B+. I need the controller to display simple visualisation via web-page (web-based control panel) and communicate with a Modbus device via UART.
I think that I will need
- an "admin panel" accessed with a password with flows editor to configure the system and
- a separate panel accesed by anyone to control the object.
I can not find anything like this in Node Red. Is it possible?
