On the Visual Flow Creator app, create a basic flow
Drag and drop between the time series node and the debug node
A function node
var newMsg = {payload: msg.payload[msg.payload.length-1].Current};
return newMsg;
A filter node
element.Current >45
A send email node
Trigger data to the flow with the inject node
Edit the Repeat inside the inject node to trigger data between an interval or at a specific time
On each node notice that:
The orange border indicates that the node is selected
The blue circle identifies nodes that have not yet been saved
The red triangle indicates missing inputs or errors in the node properties
The text below the node shows status and error messages
