Waifai

Waifai is home router telemetry. It watches the line from inside the house and answers the two things the router's own web interface will not: who is home, and when the light is coming back.

It reads who is home from who is connected, so I can check from my phone while I am nowhere near the house. And it keeps every time the light came back and the router came on with it, which turns into a fair guess at when the next one is due. Everything stays on my own network.

The problem

From anywhere that is not the house, none of this is answerable. Who is home. How much data has gone today and this month. Whether the line is genuinely slow or it just feels slow. Whether there is light. When the subscription runs out. The router knows most of it and shows me none of it, and the MTN app shows less.

I designed the screens and decided what the thing was allowed to claim; Claude Code wrote the collector, the rollups and the PWA around that.
