In the previous tutorial we created a list of 2 sensors. In this tutorial we're going to create an organ which will make senors sensors for us and 2 two automates to handle this new list.

In this part we will create a new model, named an "automate", that will be in charge of a group of sensors. This model needs 2 attributes:

name: so we can create multiple automates without losing track of and identify them
sensors: an an array of the sensors the automate is in chargethat are managed by this automate

We're going to add an empty array named automates as property of the SensorList model SensorListModel and create a model Automate which has a name and an array of sensors as attributeswith the two previously described attributes.

Take care of SensorListModel, an automate as been added to the model.

Before we can use our new model we're going to need sensors for them to handle.

The createSensor organ will create 10 virtual sensors in a new list stored as in the file "Automate".

Create a folder called createSensor and add a file called index.js inside.

createSensor/index.js

const spinalCore = require('spinal-core-connectorjs');
const models = require('../spinal-modelmodels/modelmodels.js');

console.log("Configuration Environment not found, using default config");
process.env.SPINALHUB_PORT = 7777;
process.env.SPINALHUB_IP = "127.0.0.1";
process.env.SPINAL_USER_ID = 168;
process.env.SPINAL_PASSWORD = "JHGgcz45JKilmzknzelf65ddDadggftIO98P";

const conn = spinalCore.connect(`http://${process.env.SPINAL_USER_ID}:${process.env.SPINAL_PASSWORD}@${process.env.SPINALHUB_IP}:${process.env.SPINALHUB_PORT}/`);

//  We load our automate
spinalCore.load(conn, "Automate", function (automate) {
  // callback success
}, function () {
  // callback error: We create a new list
  const list = new equipmentListmodels.SensorListModel();
  spinalCore.store(conn, list, "Automate", function () {
    addItem(list);
  });
}
);

//  We add 10 new equipments to the list
function addItem(list) {
  for (let i = 0; i < 10; i++) {
    let item = new equipmentmodels.SensorModel();

    item.id.set(i);
    item.name.set("equipment" + i);
    item.hydrometry.set(Math.floor(Math.random() * 30));
    item.temperature.set(Math.floor(Math.random() * 100));
    list.equipmentssensors.push(item);
  }
}

Install spinal-core-connectorjs from GitHub.

You can test it to see if it is working fine.

A new list file named "Automate" should have appeared in the admin UI, put . Drag & Drop it in the inspector.

You can see that that the sensor array contains 10 sensors whereas the automate array is still empty.

At this point in this tutorial our spinal system looks like this:

We are now going to create 2 automates. Each one will be in charge of 5 sensors from the list. Both will periodically choose one of their sensors and change its hydrometry and temperaturehygrometry and temperature.

Create two folders, called automate1 and automate2 and inside, create a file index.js.

Don't forget to install spinal-core-connectorjs from GitHub, inside the two folders.

Automate 1

// Loading the list
spinalCore.load(conn, "Automate", function (list) {

  if (list.automates.length < 1)
    addAutomate(list);
  press(list.automates[0]);
}, function () {
// callback error
});

// Adds an automate to the list and attributes him the first 5 equipments
function addAutomate(list) {
  var automate1 = new automatemodels.AutomateModel();

  automate1.name.set("automate0");
  for (let i = 0; i < 5; i++) {
    automate1.equipmentssensors.push(list.equipmentssensors[i]);
  }
  list.automates.push(automate1);
}

// Randomly selects a sensor in the list and changes its hydrometryhygrometry and temperature
function press(automate) {
  let selectedEquipment = Math.floor(Math.random() * 5);
  const equipmentsensor = automate.equipmentssensors[selectedEquipment];
  let hydro = Math.floor(Math.random() * 100);
  let degrees = Math.floor(Math.random() * 30);

  equipmentsensor.hydrometry.set(hydro);
  equipmentsensor.temperature.set(degrees);

// Repeats every second
  setTimeout(function () {
    console.log("automate1: has been pressed");
    press(automate);

Automate 2

Automate2 will be almost identical to automate1 so I suggest you start by copying automate1 and modify the file as follow.

  automate.name.set("automate1");
  for (let i = 5; i < 10; i++) {
    automate.sensors.push(list.sensors[i]);
  }
  list.automates.push(automate);
}

// Randomly selects a sensor in the list and changes its hydrometryhygrometry and temperature

  let hydro = Math.floor(Math.random() * 100);
  let degrees = Math.floor(Math.random() * 30);

  sensor.hydrometry.set(hydro);
  sensor.temperature.set(degrees);

    press(automate);

2 new automates with 5 sensors each should have appeared in your list. You can compare the sensors in the array and those in the automates to verify that they correspond.

We now have 2 automates that change the data of their sensors. Let's add analytic to the press function to catch those modifications.

We will change the press function in both so that when the hydrometry hygrometry exceeds 70% or the temperaturetemperature exceeds 20°, it will create a alert log.

  //  If the sensor's hydrometry or temperature are above certain value we send a message and press the sensor
  if (hydro > 70 || degrees > 20) {

Automatically create sensors using an organ
Created 2 automates to handle sensors
Made those automates display warnings if a problem occurs
