I started working on MyController version 2.x.
Existing repository renamed to mycontroller-v1-legacy.

Version 1.x: https://github.com/mycontroller-org/mycontroller-v1-legacy

Version 2.x: https://github.com/mycontroller-org/backend and https://github.com/mycontroller-org/console-web

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 GoLang
• Angular 4 front end ReactJS
• Ionic mobile application Reactive native
• Two type databases
  • RDBMS for sensor metadata In-Memory and MongoDB for data
  • InfluxDB for metrics
• backup/restore as CSV YAML 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.

@Avamander Thanks for the pointer. Discourse needs more resources than NodeBB. We do not have that much budget.
So, for now, we do not have any plans to upgrade.

@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:

@skywatch The error shown here is not related to the issue you are facing. This is error is not harmful.

Hello,
MyController 2.0 is in the development stage. I hope we can do a pre-release soon.
I do not want to limit MyController usage not only to the sensors world. can be used for another use case too.

Example:

• monitor stock market and act based on that
• monitor GitHub issues, JIRA issues act based on that
• Monitor an application on a computer
• We have many use cases...

The names should be generic and can be adaptable for all use cases.
So we need a better common name for the sensor and variable.

Current approach (In Version 1.x): Gateway >> Node >> Sensor >> Variable

Sensor:

• The sensor will be renamed as element
• I need better naming here if this is not looking good

Variable:

• We cannot use the name variable, it is more confusing.
• The Variable will be renamed as field (inputs are welcome)

Please respond back with your suggestions

between, Current work of MyController 2.0 deployed at https://demo-v2.mycontroller.org (Username:admin Password: admin)

@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); 

For now, there is no option to delete a sensor variable alone from the GUI. So I'm providing an option to delete a sensor variable from a script.

Note: This API available from 1.4.0.Final version.

• Now get SensorVariable id from Sensors page. Resources >> Sensors >> Click on view details,
  
  Now click on edit of sensor variable
  

On the URL you can see sensor variable id, This is id is important note it for your target sensor variable

Add the following script on your controller,
Extension: JavaScript
Type: Operation

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

with(myImports) {
  // pass sensor variable as bindings, example: { id: 99 }
  mcApi.sensor().deleteSensorVariable(id);
}

Execute the script as Run now (select the script and in Actions you can see Run now),
Pass the sensor variable id as bindings, here it is { id: 99 },

Click on Run. All done. Now your Sensor variable removed from MyController.

@skywatch Thanks for the logs. Can you edit and save again gateway2 and see the behavior?

@tag Thank you so much for your continued support!

when you mention influx are you planning to use the complete "TICK" stack which influxDB is part off?

Yes, I am planning to move the metrics completely to influxDB. RDBMS not good for time series data.

@blacksheepinc Hi, Yes, I had a look. And looks like we can implement with MyController with some new implementation to support for JSR223 standard(which is used in Java). Kindly create a request on github.com/mycontroller-org/mycontroller/issues When I get time I will work on this. Thank you!

@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

@skywatch Thanks to reporting this problem. I will check it in a few days and let you know.

@skywatch Thank you for the excellent feedback on 2.x release.

Just now release 1.1.0.Final

@ncollins Really this is an excellent feature request. At the same time, we need to implement a big logic to sync. Kindly create a request on GitHub page. I will start looking possible ways.

Thank you for the great idea!

@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.

@skywatch MyController does not have any specific control on DST changes. It is all about JVM capabilities in DST changes. AFAIK, JVM supports DST. MyController will overwrite your data for that hour. I do not have any idea about timers, alerts, or other scheduled operations on this duration?

@Tag @skywatch @wanvo I have created project to track 2.x requests. I have added few proposals. Kindly have a look and update the missing features? Thank you!

@boggie Passing empty string from your sketch will not replace with yours(in MyController).
The actual code to update node name in MyController, https://github.com/mycontroller-org/mycontroller/blob/development/modules/core/src/main/java/org/mycontroller/standalone/provider/ExecuterAbstract.java#L198~L202

It is a good idea to show Node EUI and sensor Id, I guess a good place to show this is on a tooltip. What do you think?

@skywatch You can see version 2 beta soon
