d-of-Things (Dashboard of Things)

dofThings is Open Source Telemetry system for the Internet of Things.

It:

• Stores data pushed from various devices. Data should be pushed in unified JSON form.
• Reacts on violated predefined thresholds - Alarms (email, xmpp) and Actions (xmpp, scripts, urls)
• Visualize data in different forms (physical elements, lamps, charts etc.)
• Has Editor for creating/changing dashboards
• Has extended logging for feeds, alarms, actions.

It is not just Web Interface for visualizing the data, but it is platform with API for push/pull/execute of data/alarms/actions. For details of all supported actions check: Includes/dofthings/classes/DataController.php

How it works (check examples/test.sh):

1. You create Feed (Add new Feed - /feeds/new/0)

2. Then automaticaly KeyID is created. Check in /keys KeyID defines the permissions (push/pull/execute) of the Feed Also it defines from which IP the request should be accepted The default created KeyID is with full permissions (push/pull/execute) and from all IP addresses

3. After the setup of Feed and KeyID, then you got the URI:

For push: http[s]:///dataPush/push/4/f4ef12415e455b93b4280318f88cbfb60d1d37d0ccdec50dff42cf86958390d8

4. How JSON should look like for the POST request

It has 2 types of elements: -Sensor - It is passive element, provides only data like temperature, humidity, door status etc

            {       "FeedID":"4",  
                    "FeedKeyHash":"f4ef12415e455b93b4280318f88cbfb60d1d37d0ccdec50dff42cf86958390d8",
                    "deviceName":"device1",
                    "deviceID":1,
                    "objectType": "Sensor",
                    "objectName": "sen3", 
                    "objectAction": "NONE",
                    "objectValue": ${VALUE},
                    "timestamp": ${TS} 
	}

-Method - It is active element, provides data about current status of the element and action URI

            {       "FeedID":"4",  
                    "FeedKeyHash":"f4ef12415e455b93b4280318f88cbfb60d1d37d0ccdec50dff42cf86958390d8",
                    "deviceName":"device1",
                    "deviceID":1,
                    "objectType": "Method",
                    "objectName": "openDoor", 
                    "objectAction": "/dofthings/4/f4ef12415e455b93b4280318f88cbfb60d1d37d0ccdec50dff42cf86958390d8/device1/active/openDoor",
                    "objectValue": 0,
                    "timestamp": ${TS} 
	}

5. After the first push, then go to Dashboards tab and create new Dashboard

6. Drag and drop some elements from left (chart, button, control panel)

7. Click the dropped element in the active dashboard field and then click on Add Feed button right to attach source to the selected element in dashboard

8. Select the sensor/method of the already push data

9. Click on update button to update the elemnt with the selected feed

10. Now save the dashboard from top left corner. You should see dialog window Created!

11. Return to main screen now and click on dashboards, you should see the already created dashboard

[12) Extended logging can be always enabled from edit page of the feed]

[13) Check Alarms tab to see how to create alarm]

!!! Remeber that Alarms will work only if valid smtp/xmpp settings are provided in Admin Settings page
