Use UI to change a object in a Context object array based on dropdown list UI
This allows the changing of variables in one object of an array of objects (stored in the example in a Context Flow file variable) based on a key in the object. Reading the variables to initiate the Drop down and number UI objects was easy, but writing them back was more difficult but this cracked it.
The example is used to adjust several variables in a thing that controls a Solar hot water system, with each variable having upper and lower limits (also stored in the object).
Just add new objects to the Context array to add new variables to adjust.
