How to support nested Loop of object(Not array)

[lucaslynn]

{
    "deviceName1": {
        "values": {
            "current": "220", 
            "voltage": "1"
        }, 
        "ts": 1721789821
    }, 
    "deviceName2": {
        "values": {
            "current": "380", 
            "voltage": "5"
        }, 
        "ts": 1721789822
    }
}

Conver to

[
  {
    "ts":  1721789821,
    "device": "deviceName1",
    "data": [
      {
        "key": "current",
        "value": 220
      },
      {
        "key": "voltage",
        "value": 1
      }
    ]
  },
  {
    "ts":  1721789822,
    "device": "deviceName2",
    "data": [
      {
        "key": "current",
        "value": 380
      },
      {
        "key": "voltage",
        "value": 5
      }
    ]
  }
]

when I loop object, I should use #currentproperty() to get current property name, but in nested loop of object, I need to get both "current property"
