Commissioning Checks

• Confirm the pump starts and stops at the expected tank levels.
• Simulate low sump level and confirm the pump stops or remains blocked.
• 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.
