BACnet address mapping

[manos@dynamitec]

Hello Admin,

I have to read 173 Analog Inputs (energy monitoring) from a BACnet server and I am looking to do it with a scheduled script that runs every 15'. 
I tested this and got a nice table in the log. 

Code:

    require('bacnet')
    device, objects = bacnet.scandevice(1)
 
    log(objects)

Trigger HVAC BACnet Polling (32/0/1) 08.05.2024 13:53:13
* table:
[1]
  * table:
  ["present-value"]
    * string: 59932.000000
  ["id"]
    * number: 1
  ["out-of-service"]
    * bool: false
  ["overridden"]
    * bool: false
  ["identifier"]
    * number: 118
  ["description"]
    * string: Mtr - Watervoeding ZKW 15F.. - Cumulated volume
  ["type"]
    * string: analog input
  ["name"]
    * string: B_02'S_EBHVAC'Plt'MtrWa(14)'CumVlm
  ["fault"]
    * bool: false
  ["in-alarm"]
    * bool: false
[2]
  * table:
  ["present-value"]
    * string: 5490.000000
  ["id"]
    * number: 2
  ["out-of-service"]
    * bool: false
  ["overridden"]
    * bool: false
  ["identifier"]
    * number: 119
  ["description"]
    * string: Mtr - Voeding verzacht labowater - Cumulated volume
  ["type"]
    * string: analog input
  ["name"]
    * string: B_02'S_EBHVAC'Plt'MtrWa(20)'CumVlm
  ["fault"]
    * bool: false
  ["in-alarm"]
    * bool: false


What I want to achieve is to access only the analog input objects and write the value to a knx group address.

• Could you provide a nice example of how can I access only the objects with ["type"] analog input and get then the ["present-value"] and write it to the knx bus on the object with the same name as the ["description"] filed?
  
• Is there a way to use this nice table data and create automatically all KNX objects based on the  ["description"] so copy the string and set as name to the knx object? In most cases Units are kWh and l (liters) but I have also °C (temperature) which I would like to recieve as 2byte float in the KNX.
