ElectriKit: Diagnostic Hardware + Guided App for Self-Troubleshooting

A $29-39 plug-in diagnostic device (size of a nightlight) that homeowners install in outlets to detect common electrical faults (open neutral, reverse polarity, voltage drop, ground fault), paired with a free mobile app that guides step-by-step troubleshooting based on what the device detects. The app walks users through safe breaker panel inspection, GFCI resets, and tells them exactly when to call an electrician and what to tell them.

Original Problem

Homeowners unable to diagnose and fix partial electrical outages without expensive electrician calls

Homeowners face sudden loss of power to specific outlets or circuits and lack the knowledge to troubleshoot the issue themselves, forcing them to call expensive electricians for what might be a simple fix like a tripped breaker or GFCI reset. Current solutions (calling professionals, online forums with slow responses) are costly and time-consuming, leaving people without power for hours or days while waiting for help.
