Write on local device with external software

[Sekiro-kost]

Hello

I have created a script, to create a BACnet device, to add values coming from different sources (loraWan, zigbee, etcc) on this bacnet device, on my Linux machine. I can also update these bacnet points via :

my_device["Current_TempLora"].presentValue = 24

No problem, I can read this information via a third-party program on another machine, on the same network.

However, I can't write to these bacnet points from an external program.

Here's how my device and its points are created:

def start_device(device, arrayCmds):
    logging.debug("Starting BACnet device")
    _new_objects = []
    try:
        for x in arrayCmds:
            formatVariableEnter = type(x['PresentValue'])
            if formatVariableEnter is str:
                continue

            new_object = analog_input(  
                instance=int(x['CmdId']),
                name=str(x['NameCmd']),
                description=str(x['Description']),
                presentValue=formatVariableEnter(x['PresentValue']),
                properties={"units": str(x['Unite'])},
            )
            
            _new_objects.append(new_object)

        for obj in _new_objects:
            obj.add_objects_to_application(device)

        return device
    except Exception as e:
          logging.error('ERREUR DANS CONSTRUCTION DEVICE BACNET AVEC LA COMMANDE >>>' + str(x['NameCmd']) + '. VERIFIEZ SES PARAMETRES (UNITES etc..) : ' + str(e))
