WolkAbout | Create a Rule 18.12

Click the Add rule button on the initial screen

New Create dialog will appear, displaying three sections needed to create a rule:

Describe rule
If
Then

Describe Rule

Describe a rule by defining its name, description and choosing its ON/OFF status which defines if the rule will be immediately active or not. All these data will be displayed on the initial Rules screen.

In Describe rule dialog enter: Rule name (e.g. Temperature Rule) and Description (e.g. Rule for Temperature) and choose its ON/OFF status which indicates if the rule is immediately active or not.

If

This section defines condition(s) that trigger the rule.

Click thebutton next to Add condition
You can choose to create Feed Condition or Semantic Group(s) Condition

Feed Condition

Choose Feed Condition to create a condition for a single feed that needs to be fulfilled for a rule to be triggered.

If you choose Feed Condition:

New section will appear with the Feed and Operators fields

Feed field: Search for the feed

Operators field: Defines a type of condition needed for the rule to be triggered. It contains a drop-down list which requires you to select one operator out of three possible groups:

Value Operator

Compares the data with the static value or with the data from another feed. According to that, you can choose between:

Is equal to
Is not equal to
Is lower than
Is lower than or equal to
Is higher than
Is higher than or equal to

If you select the operator from the value group it will open a new Compare with drop-down which requires you to choose if you want to compare it to the Static value, or another Feed.

Static value: numerically input the value for comparison

Feed: After you select to compare it with another feed, a drop-down list automatically opens where you can choose to select:

Feed: With this option, the Platform itself populates the appropriate semantic (sub)group displaying the same type of feed as the one in the previous Feed field.

Threshold: It appears if is lower than or is higher than is selected as the value operator. It requires you to enter a number which represents a minimum difference between the feeds that would consequently trigger the rule. After you have defined all the necessary settings, go to the next section.

Trend Operator

Indicates if feed’s data have Rising, Falling or Steady trend

Status Operator

Indicates if feeds have been connected or not: Connected, Inactive

Note: At this stage you can always edit the rule by adding new condition(s).

Semantic Group(s) Condition

Choose Semantic Group(s) condition to create a condition for semantic group(s). At least one condition, for one feed, needs to be fulfilled within these semantic group(s) for the rule to be triggered.

If you choose Semantic Group(s) Condition:

New section will appear
In the Reading type field, choose reading type of the feeds in the semantic group you are creating the rule for
In the Search for semantic groups field, choose semantic group from a drop-down list

Please note that you can choose more than one semantic group.

Operators field: Defines a type of condition needed for the rule to be triggered. It contains a drop-down list in which you need to select one operator out of three possible groups. These are the same types of operators used for making the condition for feeds.

If you select an operator from a value group, it will open a new Compare with drop-down which requires you to choose if you want to compare it to a Static value, or a Feed.

Static value: Numerically input the value for comparison

Feed: With this option the Platform itself populates the appropriate semantic (sub)group displaying the same type of feed as the one in the previous Feed field

Threshold: It appears if is lower than or is higher than is selected as the value operator. It requires you to enter a number which represents a minimum difference between the feeds that would consequently trigger the rule. After you have defined all the necessary settings, go to the next section.

Then

Defines action(s) that will be performed as a result. It can either inform the user about it or automate an action which will be performed on a certain device.

Options are as follows:

1. Generate Message

You will receive a message displayed on the Messages screen when a rule is being triggered.

Message field: Enter the text you would like to be displayed Message type field: Define a type of message based on its urgency

2. Send Email

You will receive an email when a rule is being triggered.

Add one or multiple number of users registered to the Platform who will receive the email
Define Subject and Body of the message

3. Send Push Notification

You are opting for push notification to be sent to a mobile phone of one or more recipients who all need to be registered to the Platform and have WolkReact Mobile application installed.

Add one or a multiple number of users registered to the Platform who will receive notification
Define Title and Body of the notification

4. Set/Actuate

You are opting for an action to be performed on a device if a rule is triggered.

New Actuators text field will open with the list of actuators (switch/slider (count)/string) and the semantic (sub)groups they belong to
Insert all the additional settings in the Value text field:
Switch the actuator ON/OFF
Send a numerical actuation value with slider (count) - its limit value is defined in device template
Send a textual actuation value with string

Note that at this stage you can always edit the rule by adding new action(s).

Click Save after you have completed all the sections
The rule will be on the Rule list on the initial Rules screen

5. Make HTTP request

Make an HTTP request to execute an HTTP action on a given target URL, if a rule is triggered.

If you choose this action:

New dialog will open with select and text fields

In Method select field choose an HTTP request method you would like to be performed.

In URL text field insert URL to a given resource.

6. Set feed status

With this option, a feed changes its status if a rule is triggered.
