Stale Data Alert
Configure Stale Data Alert in HPzenAi Smart. Warns when a connected device stops updating readings.
What it does
Warn when a sensor stops updating while still connected.
Warns when a connected device stops updating readings. Use this automation when the selected field devices should work together without repeated manual setup.
Automation Logic
Trigger
A sensor or meter reading is older than the selected stale-data limit.
Sensor data has not updated for 30 min
Example: choose "Sensor data has not updated for" and keep the default 30 min, select another preset, or enter another value.
Condition
The device still appears connected but data is not changing or updating.
No condition
Example: leave No condition selected when the trigger alone should run the workflow.
Action
Send a stale data alert.
Notify me (warning)
Example: choose "Notify me (warning)" for the default then behavior.
Allowed Time
Use All day for monitoring reliability.
All day
Example: keep All day for protection workflows, or choose Day or Night when operation should stay inside site hours.
Automation Details
Recommended use
Sensors and meters that drive dashboards, alerts, or control workflows.
Gateways, Water Meters, Level Sensors, Valves
Send a stale data alert.
Use stale-data checks for every sensor used in automatic control.
Confirm the normal update interval first, then set a stale limit above normal timing.
Before You Start
Device Readiness
Link every device used by this workflow and confirm each one is online.
Device Selection
Choose the exact tank, pump, valve, relay, or meter that should be controlled.
Safe Test
Test with safe thresholds or manual observation before leaving the workflow enabled.
Guided Setup
Set Up Stale Data Alert
Open the HPzenAi app.
Commissioning Checks
- Confirm the notification or failsafe action happens when device communication changes.
- Confirm the normal update interval first, then set a stale limit above normal timing.
- Confirm the saved card shows the correct workflow, devices, schedule, and enabled state.
- Review the event history after testing so the action is recorded as expected.
- Keep safety-critical workflows active all day unless the site needs a specific time window.
Troubleshooting
- If the Save button is disabled, complete every required trigger, condition, action, and timing field.
- If the workflow does not run, confirm the devices are online and the active time allows it to run now.
- If the action does not complete, check whether the target device is already in that state or cannot accept commands.
- If notification behavior is missing, confirm phone notification permission and recent device data.
