BENCH 42

You built
the robot.
Now make it come alive.

Bench 42 makes the hardware that bridges character robot builds and Home Assistant. Your droid doesn't just stand there — it reacts, speaks, and moves. Out of Central Florida.

GET IN TOUCH

Your house has
a voice now.

Home Assistant tracks everything — the doorbell, the dryer, the garage, the package on the porch. Normally that means glancing at your phone.

With HA Droid Connect, it means K2-SO leans out from the corner and tells you the laundry's done. R2 whistles from across the room because someone rang the bell. The Battle Droid reports, deadpan, that the garage door has been open for twenty minutes.

The information is the same. The experience is completely different.

K2-SO  ·  LAUNDRY ROOM

"The dryer cycle has completed. You're welcome, by the way."

TRIGGER: dryer.cycle_complete
R2-D2  ·  FRONT DOOR

[ urgent whistling ] — Doorbell detected. Perimeter alert.

TRIGGER: doorbell.front_pressed
B1  ·  FRONT PORCH

"Roger roger. Package delivered to front entrance."

TRIGGER: delivery.package_detected

This is what home automation feels like
when your house has character — and a builder behind it.

What We Build

42 = * = builds anything.

FEATURED PRODUCT

HA Droid Connect

The builder's answer to Home Assistant integration. Drop it in and your droid appears as a native device — servos, LEDs, and audio all working together from your dashboard. No smart speaker moves a head. No smart speaker lights up a set of eyes. You already did the hard part. This is the last piece that makes it breathe.

Home Assistant ESPHome WiFi Native Plug & Play

01

Character Builds

Life-size character builds — K2-SO, Battle Droid, R2-D2, and more — are the heart of the lab. They showcase what's possible with the HA Droid Connect and ESPHome integrations we design.

02

3D Printing

ABS, ASA, and PETG production. Custom enclosures, body panels, mounts, and parametric kits — designed to be printed, painted, and put to work.

03

Home Assistant & ESPHome

WiFi-connected everything. Automations, dashboards, media players, and smart cart integrations. If it has a power switch, it can talk to HA.
