How Level Alerts Work
The HPzenAi platform monitors each level sensor reading in real time and triggers alerts when the level crosses a configured threshold. Alerts are delivered as push notifications to the HPzenAi app on all registered phones, and optionally as SMS messages. Three alert types are available: High Level (overflow protection), Low Level (dry-run protection), and Custom Threshold (any intermediate level). Multiple alerts can be set on a single sensor.
Creating a High Level (Overflow) Alert
A high level alert fires when the water level reaches or exceeds the configured threshold — this is the primary protection against tank overflow and the resulting water wastage or property damage.

Open the HPzenAi app.
Creating a Low Level (Dry-Run) Alert
A low level alert fires when the water level drops to or below the configured threshold — this is used to prevent pumps from running dry, which causes rapid impeller and motor damage.

Open the HPzenAi app.
Creating a Custom Threshold Alert
Custom threshold alerts can be set at any level to notify operators of specific fill states — for example, 'Refill Needed' at 25% or 'Tank Ready' at 90%. Both 'rising above' and 'falling below' trigger directions are supported.
- 1Navigate to the sensor tile → Alerts → Add Alert.
- 2Select 'Custom Threshold'.
- 3Enter the threshold level in metres or percentage.
- 4Select the trigger direction: 'Rising Above' or 'Falling Below'.
- 5Enter a descriptive alert name (e.g. 'Tank at 25% — Refill Needed').
- 6Set notification recipients and method.
- 7Tap Save Alert.
Linking Level Alerts to Automated Pump Control
Connect a level sensor to a motor starter or relay controller on the same gateway to automate pump operation based on water level. This eliminates the need for float switches and provides remote visibility of pump status.

- 1Go to Gateway → Automation → New Rule in the HPzenAi app.
- 2Set the trigger: Level Sensor → Falling Below → your minimum level threshold (e.g. 20%).
- 3Set the action: Motor Starter → Start Pump (or Relay → Turn On).
- 4Add a second rule: Level Sensor → Rising Above → your maximum level threshold (e.g. 90%).
- 5Set the action for this rule: Motor Starter → Stop Pump (or Relay → Turn Off).
- 6Name both rules descriptively (e.g. 'Sump Pump Start' and 'Sump Pump Stop').
- 7Enable both rules and tap Save.
Alert History and Acknowledgement
All fired alerts are logged in the HPzenAi app under Notifications → Alert History. Each alert log entry shows the sensor name, alert type, the level at the time of trigger, and the timestamp. Alerts can be acknowledged from the history to indicate the issue has been reviewed. Unacknowledged alerts are highlighted in the app dashboard until actioned.
Alert Notification Delay
By default, alerts fire immediately when the threshold is crossed. To prevent false alerts from momentary level fluctuations (e.g. during pump start turbulence), configure an alert delay. Go to the alert settings and set 'Trigger Delay' — the level must remain above or below the threshold for the specified duration (recommended: 60–120 seconds) before the alert fires.
