Sensor-Driven Channel
Configure Sensor-Driven Channel in HPzenAi Smart. Switches a relay from a sensor reading.
What it does
Any sensor reading can flip a channel.
Switches a relay from a sensor reading. Use this automation when the selected field devices should work together without repeated manual setup.
Automation Logic
Trigger
The selected sensor crosses the configured threshold.
Tank level drops below 30%
Example: choose "Tank level drops below" and keep the default 30%, select another preset, or enter another value.
Condition
The sensor reading is recent and the relay channel is available.
No condition
Example: leave No condition selected when the trigger alone should run the workflow.
Action
Turn the relay channel on or off based on the configured action.
Turn the channel on
Example: choose "Turn the channel on" for the default then behavior.
Allowed Time
Use All day for protection or a planned window for routine operation.
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
Fans, pumps, valves, alarms, and auxiliary controls driven by sensor values.
Relay Controllers, Motor Controllers, Valves
Turn the relay channel on or off based on the configured action.
Use hysteresis or a band where frequent threshold crossings are possible.
Set a temporary threshold and confirm the correct channel switches.
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 Sensor-Driven Channel
Open the HPzenAi app.
Commissioning Checks
- Confirm the selected relay channel changes state at the expected time or condition.
- Set a temporary threshold and confirm the correct channel switches.
- 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.
