  • Purpose: Check if the hardware works properly and if the appearance is intact.
  • Scenario: Hardware operation.
  • Method: Manual operation and visual inspection.
  • Criteria: The hardware such as the LED indicator and button works properly.
  • Possible issues: Incorrect indicator behavior. Device control issues.

Network management

  • Purpose: Check if the device can be paired.
  • Scenario: First-time device pairing.
  • Method: Trigger the device under test to enter pairing mode. Use the provided mobile app to pair with this device.
  • Criteria: The device can be paired and controlled by using the app.
  • Possible issues: Pairing failed. This might be because the network has an issue, the device is still bound with another app account, or the mobile phone does not use a 2.4 GHz network.

Status sync

  • Purpose: Check if the device can correctly execute commands and report status to the cloud.
  • Scenario: When the device is paired, or connected after power on or disconnection, users view the current device status.
  • Method: Check if the app displays the updated status when the device is paired, or connected after power on or disconnection.
  • Criteria: The device status is correctly updated on the app when the device is paired, or connected after power on or disconnection.
  • Possible issues: Incorrect device status. This might be because the network has an issue, or the device fails to report status to the cloud.

Indicator behavior

  • Purpose: Check if the LED indicator can behave properly.
  • Scenario: When the device is paired, or connected after power on or disconnection, users check the indicator status.
  • Method: Check the LED indicator’s behavior when the device is paired, or connected after power on or disconnection.
  • Criteria: The LED indicator behaves as expected when the device is paired, or connected after power on or disconnection.
  • Possible issues: The indicator light does not work.

Schedule

  • Purpose: Check if a scheduled task is run as expected.
  • Scenario: Schedule the device to turn on or off automatically.
  • Method: Set a schedule by using the app and check the execution result.
  • Criteria: The scheduled task is run as expected.
  • Possible issues: The scheduled task fails to be run due to network disconnection.

Countdown

  • Purpose: Check if a countdown timer is executed as expected.
  • Scenario: Schedule the device to turn on or off automatically.
  • Method: Set a countdown timer by using the app and check the execution result.
  • Criteria: The countdown timer is executed as expected.
  • Possible issues: The timer fails to fire.

Random schedule

  • Purpose: Check if a random schedule is run as expected.
  • Scenario: Schedule the device to turn on or off randomly.
  • Method: Set a random schedule by using the app and check the execution result.
  • Criteria: The random schedule is run as expected.
  • Possible issues: Failed to create a random schedule.

Cycle schedule

  • Purpose: Check if a cycle schedule is run as expected.
  • Scenario: Schedule the device to turn on or off circularly for a specified duration.
  • Method: Set a cycle schedule by using the app and check the execution result.
  • Criteria: The cycle schedule is executed as expected.
  • Possible issues: Failed to create a cycle schedule or execute the schedule.

Inching switch

  • Purpose: Check if the inching switch is executed as expected.
  • Scenario: Enable the device to turn off automatically after being on for a specified period.
  • Method: Set the inching switch by using the app and check the execution result.
  • Criteria: The inching switch is executed as expected.
  • Possible issues: The inching switch is not executed as it should be.

Child lock

  • Purpose: Check if the child lock works.
  • Scenario: Avoid any misoperation of the device.
  • Method: Enable the child lock by using the app and check if it works.
  • Criteria: With the child lock enabled, the device cannot be controlled with physical buttons.
  • Possible issues: The child lock cannot be released.

LED indicator setting

  • Purpose: Check if the LED indicator behaves as per the setting.
  • Scenario: The LED indicator blinks when the device status changes.
  • Method: Set the LED indicator mode by using the app and check if it works.
  • Criteria: The LED indicator blinks as expected.
  • Possible issues: The LED indicator setting does not work.

Power loss recovery

  • Purpose: Check if the device returns to the preset state when the power comes back after an outage.
  • Scenario: Enable the device to come on in the preset state following a power loss.
