And, for completeness, I can do the same thing in the “Call service node” to summon notify and use this JSON code:
{"message": "Wind speed tomorrow is " & msg.payload*2.24 & " miles/hr","title":"Wind speed is high tomorrow"}
I wish I could have the whole object as an input to the call service node, and manipulate ALL the variables, but I can’t figure that out. So you have to only pass along one variable at a time, input as type “number” (not string), and calculate the msg.payload.
I don’t understand what you mean but I’m very sure it’s possible.
