Innotas Water Sensor Decoder⁠

⁠Description

Decoder for Innotas Water Sensor decodes "data" payload into human-friendly format. Depending on incoming fPort value output will provide:

current meter reading in Liter
meter reading on due day in Liter
min. flow rate of last day
max. flow rate of last day
duration of standstill of last day
number of last day’s meter starts
flow volume in previous hour
flow volume in previous 2 hours
flow volume in previous 3 hours
flow volume in previous 4 hours
Incoming payload looks like this

{

  },
  "confirmedUplink": true,
  "devAddr": "AUIKYQ=="
}

Decoded output passed to next module via POST call, depending on fPort will look like this

{
	"timestamp": 1657536280458,
	"devEUI": "b0b353fffe40366a",
	"deviceName": "B0B353FFFE40366A",
	"currentMeterReading": 909,
	"maxFlowOfLastDay": 0,
	"durationStandStillLastDay": null,
	"lastDayMeterStarts": 0,
	"minFlowOfLastDay": 0
}

Depending on environment variables NESTED_RESPONSE output can be nestd with few fields or with all fields in "data" property, for example:
- when nested

{
  timestamp: '1647945089527',
  devEUI: 'B0B353FFFE40366A',
  deviceName: 'B0B353FFFE40366A',
  data: {
    	currentMeterReading: 909,
      maxFlowOfLastDay: 0,
      durationStandStillLastDay: 1,
      lastDayMeterStarts: 0,
      minFlowOfLastDay: 0
  }
}

- when not nested

{
  timestamp: '1647945089527',
  devEUI: 'B0B353FFFE40366A',
  deviceName: 'B0B353FFFE40366A',
  currentMeterReading: 909,
  maxFlowOfLastDay: 0,
  durationStandStillLastDay: 1,
  lastDayMeterStarts: 0,
  minFlowOfLastDay: 0
}
