Hello everyone,

MyController was born around August 2015. Currently, version 1.0.0 available for public and before 25, December 2017, version 1.1.0 will be available for the public.

• I see some performance issues with MyController when we have a number of sensors grow.
• We need end user-friendly GUI. I believe for now we have only admin friendly GUI.
• There is no mobile application.
• Supports more databases. H2DB, MySQL, MariaDB, PostgresSQL. To reduce complexity support only for one DB or maximum two databases.
• and more

To rectify all these issues, I am planning to build MyController 2.x from scratch. With the following technologies.

• Spring boot with Undertow
• Angular 4 front end ReactJS
• Ionic mobile application Reactive native
• Two type databases
  • RDBMS for sensor metadata
  • InfluxDB for metrics
• backup/restore as CSV or JSON file(except metrics data)

Still, I want to keep MyController's primary platform as Rasberry PI.

Kindly share your experience with influxDB and raspberry PI in the long run. Also, share your thoughts on this big move.

With the request https://github.com/mycontroller-org/mycontroller/issues/47 we have introduced an option to add custom buttons with custom payload on dashboard.

We can use this widget for multiple purpose. Here I have showed how to use it as a TV remote control. For this you should have IR send sensor board in front of tv.

Edit dashboard and select add widgets. Select Sensor custom buttons
Now select your IR send type sensor variable.
You have to give 3 types of input

• Minimum height - each button minimum height in px
• Minimum weight - each button minimum weight in px
• JSON - is the buttons/payloads configuration

To create json configuration error free way use http://www.jsoneditoronline.org/

In configuration we can give name, payload, btnType.

• name - (Mandatory) Name of the button. can be in the form of HTML also. HTML or icons(recommended: font awesome icons)
  are mandatory fields.
• payload - (Mandatory) When we click the button what is the payload we have to send
• btnType - (Optional) can be any one of value in the list [default, primary, success, info, warning, danger] when we leave this field field as blank, default will be selected. Each value gives different color

Example json configuration as follows,

[
  {
    "name": "<i class='fa fa-power-off'></i>",
    "payload": "P",
    "btnType": "danger"
  },
  {
    "name": "1",
    "payload": "1"
  },
  {
    "name": "2",
    "payload": "2"
  },
  {
    "name": "3",
    "payload": "3"
  },
  {
    "name": "4",
    "payload": "4"
  },
  {
    "name": "5",
    "payload": "5"
  },
  {
    "name": "6",
    "payload": "6"
  },
  {
    "name": "7",
    "payload": "7"
  },
  {
    "name": "8",
    "payload": "8"
  },
  {
    "name": "9",
    "payload": "9"
  },
  {
    "name": "0",
    "payload": "0"
  },
  {
    "name": "<i class='fa fa-play'></i>",
    "payload": "PL",
    "btnType":"success"
  },
  {
    "name": "<i class='fa fa-pause'></i>",
    "payload": "PA",
    "btnType":"warning"
  }
]

Note: In this example I have added dummy payloads. Real payload of TV remote will be different(TV to TV payload will be different).

Final result:

joaopauloss created this issue in mycontroller-org/mycontroller

closed Remote control buttons in MyController #47

@BenCranston For now MyController will not support for MySensors RSSI. I have to check development version of MySensors to support this feature for MySensors.
RSSI created for future use. Have plan to support LoRa (TheThingsNetwork.org), there we have RSSI.

@Takero1978 said:

Group Button for dashboard

Please create a request on Github. I will add group button for dashboard.

@mibu I will look in to implementation details. I will come back with the level of easiness implementation.

@DaTTcz For now direct battery support not available on Rules. However you can do it from script. I will update how to handle with script.

Kindly create a request on github page to support battery level on rules.

ALL these features are available on SNAPSHOT build

Enter your condition via script,

Steps:

• Create UID Tag for your node,
• Create script to check node battery level (script type: Condition)
• Create rule with this condition script
• Enjoy

Create UID Tag:

Add script:

Java Script to check battery level,

var myImports = new JavaImporter(java.io, java.lang, java.util, java.text);

with(myImports) {
  var mcResult = false; //By default this is false. When your condition meets change this to true
  var batteryLevel = mcApi.uidTag().getByUid("node1").resource.batteryLevel;
  if(batteryLevel >= 50){ // Your condition
     mcResult = true;
  }
}

Add rule:

@Velo17 It is there in the user manual. You can edit the following to change default certificate.

mcc.web.ssl.keystore.file=../conf/keystore.jks
mcc.web.ssl.keystore.password=mycontroller
mcc.web.ssl.keystore.type=JKS

@njbuch I am sorry for the delay. I was bit busy with other tasks. I will generate a getting started soon. Thank you for your patience.

@njbuch I have updated quick start guide. Kindly let me know if you face any issue.

@Tetnobic

Data retore complete log message is show 7 seconds after shutdown message log, but it works

Looks like taking some time to restore on your machine.
However, the following message says shutdown complete. Which leads confusion for you. I will sync these messages. Thank you! No worries

2017-01-17 11:21:28,290 INFO [MyController.org Shutdown-Hook] [org.mycontroller.standalone.AppShutdownHook:36] Bye, Have a nice day! See you soon

@Tetnobic This ticket resolved. You can check this on our latest SNAPSHOT version.

@Tetnobic fixed this restore issue on the slow environment too. Thanks to reporting this issue. This is a nice catch! Updated changes on SNAPSHOT build.

fixed restore issue

@Tetnobic Good news

I have updated this request on https://github.com/mycontroller-org/mycontroller/commit/c6cfe4e56bafb7f1bc59e745f13672191ad2e8a6

You can test this on SNAPSHOT version.

Currently, Minimum time should be 5 minutes. As check will happens only 5 minutes once.

You have to include the following property on Node properties to override global aliveCheckInterval

"aliveCheckInterval": 5

Note: Should be an integer. Values are in the minute.

0 jkandasa committed to mycontroller-org/mycontroller

allow to set node alive check for each node, min time 5 minutes

@Tetnobic Changed this feature bit different. You have to enable Enable unique name checkbox to get unique chart name.

@njbuch

Any tips and tricks to share?

You can do it from server. No need to touch your device

This feature is available in recent SNAPSHOT version.

You have to create an external server as shown,

Assign sensors variable or sensor or gateway to this external server.

All done

@njbuch You can not add more sensor variables to one line.
however,

• if you configure a sensor it will send all the sensor variables data under the sensor.
• If configure a node it will all the sensor variables data under the node.
• If you configure a gateway it will send all the sensor variable data under the gateway.

If the above configuration does not meet your requirements, you have to create multiple entries.

@Tetnobic Thanks to reporting this issue. This is fixed and pushed changes on SNAPSHOT version. Kindly clear your cache and test with latest SNAPSHOT version.

Thank you!

@njbuch I never tested sleep and wake up. Let me try and update, when I get time.

@esawyja To achieve this we can create a script, rules, and template, repository variable, uid tag.

• Create Uid tag for your generator status variable.
  

• Create repository variable to store and calculate usage. Note: when you want to reset your calculation, update all these values as 0
  

• Create script,
  

//To run this script you need to pass the following bindings
// {"deviceUid":"generator-status", "repositoryKey":"generator-hour-meter"}
var myImports = new JavaImporter(java.lang, java.util, org.mycontroller.standalone.utils.McUtils);

with(myImports) {
  var generator = mcApi.uidTag().getByUid(deviceUid).getResource();
  var meter = mcApi.variable().get(repositoryKey);
  var status = {};
  var saveChanges = false;

  // If user requested to reset.
  if(meter.value2 === '0'){
    status.enabled = 0;
    status.start = 0;
    status.end = 0;
    meter.value = 0;
    meter.value2 = Date.now();
    meter.value3 = JSON.stringify(status);
    meter.save();
  }

  //Copy caclulation data from repository
  status = JSON.parse(meter.value3);

  if(generator.value === '1' && status.enabled == 0){
    status.start = Date.now();
    status.enabled = 1;
    saveChanges = true;
  }else if(generator.value === '0' && status.enabled == 1){
    status.end = Date.now();
    status.enabled = 0;
    meter.value = parseInt(meter.value) + (status.end - status.start);
    saveChanges = true;
  }
  //Save changes to repository
  if(saveChanges){
    meter.value3 = JSON.stringify(status);
    meter.save();
  }

  //Calculate usage and update to display
  var time = {};
  time.raw =  (status.enabled == 0 ? 0 : Date.now() - status.start) + parseInt(meter.value);
  time.hour = 0;
  time.minute = 0;
  time.second = 0;
  var timeTemp = time.raw;
  //Update hour
  if(timeTemp > McUtils.HOUR){
    time.hour = (timeTemp / McUtils.HOUR) | 0;
    timeTemp %= McUtils.HOUR;
  }
  //Update minute
  if(timeTemp > McUtils.MINUTE){
    time.minute = (timeTemp / McUtils.MINUTE) | 0;
    timeTemp %= McUtils.MINUTE;
  }
  //Update second
  if(timeTemp > McUtils.SECOND){
    time.second = (timeTemp / McUtils.SECOND) | 0;
  }
  time.str = {};
  //Update time as string value
  time.str.hour = (time.hour < 10 ? '0' : '') + time.hour.toString();
  time.str.minute = (time.minute < 10 ? '0' : '') + time.minute.toString();
  time.str.second = (time.second < 10 ? '0' : '') + time.second.toString();
}

• Create an Operation with bindings to execute this script, Bindings: {"deviceUid":"generator-status", "repositoryKey":"generator-hour-meter"}
  

• Create Rule to trigger this script, when there is a change on your generator,
  Rule#1:
  
  Rule#2:
  

• Create HTML template to display on dashboard,
  

<div class="adf-myct">
    <div class="adf-myct-time">${time.str.hour}:${time.str.minute}:${time.str.second}</div>
    <div class="adf-myct-date"><small><I>Since:</I> {{ ${(meter.value2)!"Never"} | date:mchelper.cfg.dateFormat:mchelper.cfg.timezone}}</small></div>
</div>

• Configure your template and script on Dashboard,
  

Displaying time format: hour:minute:second

@seant

var pingDistance = tankDistanceSensor.value; //Water tank level percent

You have to use parseInt(tankDistanceSensor.value), Sensor variable always have String value.
var pingDistance = parseInt(tankDistanceSensor.value); //Water tank level percent

//THESE 2 LINES DO NOT SEEM TO SET THE VALUES
tankLitresSensor.setValue(litres);
tankPercentageSensor.setValue(percentage);

After these two lines add the following lines,

  mcApi.sensor().sendPayload(tankLitresSensor); 
  mcApi.sensor().sendPayload(tankPercentageSensor);
