Here is the response I'd like:

• for both xra and xrp devices return:

{
  measurements: [
    {
      name: 'C1',
      step: 0.5,
      minimum: 28,
      measurementUnit: "cm",
      maximum: 20,
      default: 25,
      instructions: 'instructions go here'
    },
    {
      name: 'C2',
      step: 0.5,
      upper_range: 28,
      measurement_unit: "cm",
      lower_range: 20,
      default: 25,
      instructions: 'instructions go here'
    },
    {
      name: 'C3',
      step: 0.5,
      upper_range: 28,
      measurement_unit: "cm",
      lower_range: 20,
      default: 25,
      instructions: 'instructions go here'
    },
    {
      name: 'C4',
      step: 0.5,
      upper_range: 28,
      measurement_unit: "cm",
      lower_range: 20,
      default: 25,
      instructions: 'instructions go here'
    },
    {
      name: 'L1',
      step: 0.5,
      upper_range: 32,
      measurement_unit: "cm",
      lower_range: 18,
      default: 25,
      instructions: 'instructions go here'
    },
   {
      name: 'L2',
      step: 0.5,
      upper_range: 28,
      measurement_unit: "cm",
      lower_range: 20,
      default: 25,
      instructions: 'instructions go here'
    }
  ]
}
