I’d like to add warning lights to my dashboard to track when certain events take place.
But I need the lights to have a custom appearance so I prefer not to use existing nodes for this.
My first thought was to use the ui-template mode with svg to create vector circles and with js to control the graphics using msg.payload as a command signal.
But I cannot access msg.payload in my ui-template block.
Is there a better way to do this?
