Notifications

Email notifications alert designated recipients when air quality thresholds are exceeded, enabling proactive response to elevated PM levels.

Accessing Notifications

Navigate to /sites/[id]/notifications or click "Notifications" in the site sidebar.

Concept

Notification rules define:

  • Trigger device: AirWatch sensor to monitor

  • PM10 threshold: Level that triggers alert

  • Recipients: Email addresses to notify

  • Hysteresis: Prevents notification spam

Notification Components

Trigger Device

AirWatch sensor that triggers notifications:

  • AirWatch 3.0

  • AirWatch LTE Europe

  • AirWatch LTE America

PM10 Threshold

The PM10 value (in µg/m³) that triggers notification:

  • Alert sent when threshold exceeded

  • Configurable per rule

Recipients

Email addresses to receive alerts:

  • Multiple recipients supported

  • Valid email format required

  • Both internal and external addresses

Hysteresis

Time delay before re-triggering:

  • Prevents repeated notifications

  • Configurable duration

  • Value must drop and rise again to re-trigger

Creating Notifications

Add Notification Modal

1

Select Create Notification Rule

Click "Create Notification Rule" to open the modal.

2

Choose Trigger Device

Select the trigger AirWatch device for the rule.

3

Set Threshold

Set the PM10 threshold that will trigger the alert.

4

Add Recipients

Add recipient email addresses (see Recipient Management).

5

Configure Hysteresis (optional)

Set hysteresis duration to prevent repeated alerts.

6

Save Notification

Save the notification rule to activate it.

Recipient Management

Add recipients:

  • Enter email address

  • Click "Add"

  • Repeat for multiple

Remove recipients:

  • Click remove button next to email

  • Confirm removal

Notification Cards

Each notification displays as a collapsible card.

  • Notification name

  • Trigger device name

  • Enable/Disable toggle

  • Edit/Delete buttons

Card Content

  • Trigger device with current PM10

  • Threshold value

  • Recipient list

  • Notification status

Managing Notifications

Enable/Disable

Toggle notifications on/off:

  • Disabled rules don't send emails

  • Useful for maintenance periods

  • Quick pause capability

Edit Notification

Modify existing notifications:

  • Change threshold

  • Adjust hysteresis

Delete Notification

Remove notifications:

  • Confirmation required

  • Cannot be undone

Email Content

Alert Email Contains

  • Site name

  • Trigger device name and location

  • Current PM10 value

  • Threshold that was exceeded

  • Timestamp

  • Link to dashboard (if configured)

Language

Email templates available in:

  • English

  • German

Based on system configuration.

Notification Behavior

Trigger Condition

1

Condition: Threshold Crossing

PM10 exceeds the configured threshold.

2

Condition: Hysteresis

Hysteresis period has passed (if applicable).

3

Condition: Rule Enabled

The notification rule is enabled.

Hysteresis Logic

Prevents spam. Steps for how hysteresis works:

1

Initial Alert

Alert sent when PM10 crosses the threshold.

2

Start Timer

A hysteresis timer starts after the alert.

3

Suppress Alerts

No new alerts sent during the timer period.

4

Require Reset

PM10 must drop below the threshold to reset state.

5

Restart Timer on Drop

Timer resets when the value drops below the threshold.

6

Next Alert

A new alert is sent only on the next threshold crossing after reset.

Example

Threshold: 100 µg/m³, Hysteresis: 30 minutes

Time
PM10
Action

09:00

110

Alert sent

09:05

120

No alert (hysteresis)

09:15

90

No alert (below threshold)

09:20

105

Alert sent (new crossing)

Live Status

Notification cards show:

  • Current PM10 from trigger

  • Whether threshold exceeded

  • Active alert state

Best Practices

Threshold Selection

  • Set above normal fluctuations

  • Consider background levels

  • Test before production use

Recipient Selection

  • Include relevant personnel

  • Consider shift supervisors

  • Avoid notification fatigue

Hysteresis Settings

  • Too short = notification spam

  • Too long = missed alerts

  • 15-30 minutes typical

Empty State

If no notifications exist:

  • Message indicating no rules

  • "Create Rule" button

Permissions

Creating/editing notifications requires:

  • Member or Admin role

  • Access to trigger devices

  • Active licenses
