Testing Procedure and Checklists

WanderShade WV-SHADE-LITE & WV-SHADE-SOLAR

Test Checklist

1. Initial Visual Inspection

• Ensure the motor housing is free of visible damage.
• Confirm the saffron pull-cord nub is secure and intact.

2. Battery Check (WV-SHADE-LITE)

• Disassemble battery compartment using Torx T6 screwdriver (Part #12345

#12345).

• Verify battery terminals are clean; inspect for corrosion.
• Conduct voltage test: 3.7V nominal, measured within ±0.2V tolerance.

3. Solar Panel Inspection and Test (WV-SHADE-SOLAR)

• Inspect solar panel connectors (Part #67890) for damage or contaminati

contamination.

• Measure open-circuit voltage using multimeter: 5.1-5.4V expected range

range, measured within ±0.2V tolerance.

4. Motor Functionality Test

• Power motor through battery or solar charge circuit; observe steady op

operation without stalling or jerking.

• Verify motor RPM under load (30lb for WV-SHADE-LITE, 50lb for WV-SHADE

WV-SHADE-SOLAR) matches manufacturer specs: 4-6RPM at 12V nominal.

5. Microcontroller Firmware Check

• Connect to Shade via USB (FTDI Part #11223) and verify firmware versio

version.

• Ensure ESP32-S3-WROOM-1 module (Part #98765) is properly flashed with

current production release.

6. Thread/Matter Connectivity Test

• Pair device to Thread or Matter network using supported smart home app

app; confirm successful mesh connection.

• Run series of state-change tests over the wireless link: up, down, sto

stop commands verified.

Troubleshooting Guide

• Battery voltage below 3.5V: Replace batteries (Part #12346).
• Motor stalls under load or makes loud noises: Inspect gear train alignmen

alignment; replace motor if necessary.

• Firmware error codes logged: Flash with latest release using appropriate

programming tools (e.g., PlatformIO).

Firmware Roll-Back

Procedure for Rolling Back to Previous Release

WanderShade WV-SHADE-LITE & WV-SHADE-SOLAR

Steps to Follow

1. Identify Current and Target Firmware Versions

• Confirm current firmware revision via USB connection or by accessing d

device settings in the smart home app.

• Determine target roll-back version based on release notes or support d

documentation.

2. Preparation for Roll-Back

• Backup any custom configurations or data stored locally within WanderS

WanderShade’s memory (if applicable).

• Ensure you have access to the previous firmware binary file and the ne

necessary programming tools (e.g., PlatformIO).

Decommission + Secure-Wipe

Guidelines for Proper Device Disposal

WanderShade WV-SHADE-LITE & WV-SHADE-SOLAR

Security Considerations During End-of-Life Processing

1. Data Erasure

• Perform a secure wipe of all local memory and settings stored within t

the device’s firmware.

• Use certified data sanitization software (e.g., BleachBit) to overwrit

overwrite storage areas multiple times.

2. Physical Destruction

• Disassemble motor housing; remove microcontroller module (Part #98765)

#98765).

• Shred or grind sensitive components to render them irreparable and uni

unidentifiable.

• Verify no identifiable information remains on the device’s PCBs before

before final disposal.

3. Environmental Compliance

• Ensure all disposed materials comply with local waste management regul

regulations.

• Recycle metals (e.g., copper wiring, aluminum frames) through certifie

certified recycling facilities.

• Dispose of batteries and solar panels according to hazardous waste gui

guidelines.
