So this is a continueation of this thread from January right?
As far as I remember, all you had to do was drop the http request
node in (that you had on your first/original flow) & it should of worked! (assuming the demo data you provided in Post#19 was correct)
So if you put the http request node from your original flow in place of the "fake device requests" function what happens?
PS: attach a debug to the ↑ http request node
Show us.
