Hi @SK_9989757.

 

Is there some reason you're asking?  This should only be a problem if your contract limits the number of assets.  Refer to the response from @M4RC for determining the number of things allowed.

 

Regards.

Hi @SK_9989757 

 

First, you can check your license limitation as mentioned in another comment. 

 

If it is more than 6000 you can check by yourself using the following script. If the output is the same as the thingcreated then it should work well to create 6000 MQTT things on ThingWorx. You need to set up your own MQTT broker first.

 
thingcreated = 6000;
result = 0;
for (i = 1; i < thingcreated + 1; i++) {
  thingName = "CreatedMQTT-" + i;
  let params = {
    name: thingName /* STRING */,
    description: undefined /* STRING */,
    thingTemplateName: "MQTT" /* THINGTEMPLATENAME */,
    projectName: "PTCDefaultProject" /* PROJECTNAME */,
    tags: undefined /* TAGS */,
  };
  // no return
  Resources["EntityServices"].CreateThing(params);
  let configTable = Things[thingName].GetConfigurationTable({
    tableName: "ConnectionInfo" /* STRING */,
  });
  configTable.rows[0].clientIdFormat = "/Thingworx/{s}/{t}";
  configTable.rows[0].useSSL = false;
  configTable.rows[0].serverName = "localhost";
  configTable.rows[0].serverPort = 1883;
  configTable.rows[0].userId = "testuser";
  configTable.rows[0].password = Resources["EncryptionServices"].EncryptPropertyValue({
    data: "testuser" /* STRING */,
  });
  Things[thingName].SetConfigurationTable({
    configurationTable: configTable /* INFOTABLE */,
    persistent: undefined /* BOOLEAN {"defaultValue":true} */,
    tableName: "ConnectionInfo" /* STRING */,
  });

  // let result = Things[thingName].GetConfigurationTable({
  //   tableName: "ConnectionInfo" /* STRING */,
  // });
  Things[thingName].EnableThing();
  Things[thingName].RestartThing();
  if (Things[thingName].isConnected) {
     result++;
   }
}
 
Best Regards
