Hi folks, I'm wondering how forwardInputMessages in a UI node works. The dashboard Switch-node has following setting: [image] By looking at the Switch-node ( code ), it is being used like this: forwardInputMessages: config.passthru, But when I use it like that in the node-red-contrib-ui-multista…

The config text and the help text for the ui_switch are misleading. It either passes through or it doesn't. Simple as that. In addition, If the payload matches one of the switch states, then it sets the switch, if not it doesn't set the switch.

Hey Colin, Thanks a lot for your explanation!

In fact they are plain wrong really. I keep meaning to do a PR to improve them but haven't got round to it.

Do you mean that you want that the input msg should only be forwarded when the state changes, like the checkbox label describes?

No, sorry, I should have been clearer. The operation is perfect, it is the the dialog and help text that need sorting.

Ah yes, what I said is not quite true. When in non-pass through mode, if the node is set to Show State of Output then the incoming message does not set the state of the switch, but may affect other attributes of the switch.
