What error?
I'm not seeing any error messages.
What is causing you concern?

Dashboard ui not working

Have you added any dashboard nodes, such as a button or switch?
If not, there will be nothing to display.

not. only inject and rpi-gpio out node..

Well that's why your dashboard isn't working.
Try adding some.

The photos are not helping!

You need to add one or more nodes from the dashboard set of nodes, otherwise there is nothing to display.
Also read the dashboard instructions.


can you teach me to do it?

I apologize if I speak incomprehensibly...i want to learn to work with raspbery.. :slight_smile:

thanks for trying to help

You must describe in much more detail, what you are trying to achieve, and what is not working.
Otherwise it's difficult to help you.

my purpose is these relays. I want to manage them remotely
RPi Relay Board (B) - Waveshare Wiki

Well the topic title is currently ERROR: Welcome to the Node-RED Dashboard Please add some UI nodes to your flow and redeploy which does not describe your problem.

I'll change it to something more suitable and then someone will hopefully be able to help you

i added a switch and everything works. Thank you very much
