Am i missing out on anything by not using templates and just using the generic note.add to data file request?
In this scenario, not likely, but it may be worth testing. When using templated Notefiles, you’ll likely consume less cellular data (though depending on the payload that may or may not be significant). I’d recommend reading Working with Note Templates to see if they may be right for your project.
For routes does it send 1 route for each capture or 1 route on each upload?
Each event is routed separately (per each capture).
If it sends 1 route per each CAPTURE is there a way to bundle it to be more economical on my route usage?
Yes, I suppose you could create a list/array of events and save those in the body as a single Note when you’re ready to save to the Notecard and sync with Notehub. You’d then have to unpack the list on the backend.
