Hi, can you clarify...

- What do you mean by "initial all node"

- What do you mean by "send out when UI is first start"?

Dear Steve-Mcl :

ok, I try to say it clear.

example :

1. When UI is start, A Button payload is fault.
2. And then I hope text is show "Press button to read AD".
3. And the gauge is show 0.
4. When I press A Button.
5. Then text is show "AD is reading".
6. Process of reading AD.
7. And the gauge is show AD value.

Thank u.

So you are talking about setting initial values on UI elements in the dashboard.

- Is this when re-starting node-red?
  - For this, you can use an inject node set to trigger xxx Seconds after starting

OR

- When opening the Dashboard page (the one with Button and Gauge)?
  - For this, you can use UI\_CONTROL to fire the button

NOTE: you will need to set option on button
