Speak naturally.
Lipi understands.

Hold, speak, release. The orb pulses to your voice in real time and the command lands on your relays before you finish exhaling.

Nº 03 — Anywhere

Control from
your pocket.

Not home? Send a WhatsApp to your Lipi number. The same language model, the same relays — no VPN, no port forwarding, no subscription.

Nº 04 — Everywhere

One home.
Every device.

Native iOS, native Android, Mac Catalyst, a PWA, and WhatsApp as a fallback — all in lockstep over the same Go cloud.

Nº 05 — Setup

Up and running
in five minutes.

Plug the box in, hand it your home WiFi, type the pair code once. It's yours.

01

Power on.

The box boots its own setup hotspot named Lipi-XXXX.

02

Join it.

Connect your phone to that hotspot — a captive portal opens automatically.

03

Give it WiFi.

Pick your home network, type the password, tap Connect.

04

Claim it.

Paste the 8-character pair code into the Lipi app. Done.

Nº 06 — The hardware

A box you
barely notice.

An ESP32 relay controller with four 10A channels, matte soft-touch chassis, and enough glow to find in a dark room. Flash it, mount it, forget it.
