fritzctl 1.4.20

• Command temperature supports reset to "comfort" and "saving" via

   fritzctl temperature comf <devices>
   fritzctl temperature sav <devices>

  respectively.
• Experimental: list thermostats as well as list switches now have an option --output=json, which serializes the data into json format and prints it to stdout. An example is:

  {
    "numberOfItems": 1,
    "devices": [
      {
        "id": "44363 2777777",
        "internalId": "12",
        "name": "HKR_1",
        "properties": {
          "vendor": { "manufacturer": "AVM", "productName": "Comet DECT", "firmwareVersion": "03.54"  },
          "lock": { "hwLock": "LOCKED", "swLock": "UNLOCKED" },
          "warnings": [ "Battery is running on low capacity" ]
        },
        "measurements": { "temperature": "20.5" },
        "state": {
          "connected": true,
          "temperatureControl": { "goal": "OFF",  "saving": "18",  "comfort": "20", "nextChange": { "at": "2017-09-30T23:00:00+02:00", "goal": "20"  }  }
        }
      }
    ]
  }
