Tank & Pump
Tank Low Alert
Configure Tank Low Alert in HPzenAi Smart. Notifies users before a tank reaches a critical low level.
What it does
Get notified before the tank runs dry.
Notifies users before a tank reaches a critical low level. Use this automation when the selected field devices should work together without repeated manual setup.
Automation Logic
Trigger
Tank level drops below the selected low alert point.
Tank level drops below 20%
Example: choose "Tank level drops below" and keep the default 20%, select another preset, or enter another value.
Condition
The tank reading is recent and the alert is enabled.
No condition
Example: leave No condition selected when the trigger alone should run the workflow.
Action
Send an alert so users can refill, inspect, or switch source before water runs out.
Notify me (warning)
Example: choose "Notify me (warning)" for the default then behavior.
Allowed Time
Use All day for water availability alerts.
All day
Example: keep All day for protection workflows, or choose Day or Night when operation should stay inside site hours.

Commissioning Checks
- Confirm the pump starts and stops at the expected tank levels.
- Set a temporary alert threshold above the current level and confirm the notification is received.
- 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.
