Node-RED nodes for hubitat

I asked a support question about the output of the Maker API (because it ends up coming through as output from the NR hubitat device node):

I don't want to rehash the whole question here, but I did what to ask if anyone has built something in NR that turns what the Maker API calls a JSON_Object into actual JSON. I did the conversion by hand in that other topic and can imagine building a really complex parsing conversion function node, but I am hoping that someone else has already invented that wheel.

To be clear the device node is doing exactly what I would expect it to, but the Maker API is labelling something that I don't think is JSON as JSON, but I want the data that would be easy to get to if it were actually JSON.
