What is this?

SwitchRoo is a replacement PCB that drops into standard Bunnings touch switch housings, giving you a fully local smart switch with no cloud dependency and features the original never had.

1

Grab a switch from Bunnings

Pick up a Deta touch light switch. Significantly cheaper than the smart variants, and available at any Bunnings.

2

Drop in the SwitchRoo PCB

Simply unplug the original low voltage board and plug in SwitchRoo using the same pin headers. Installation must be performed by a licensed electrician. No wiring changes required.

3

Connect and go

Power it on and connect to your WiFi. SwitchRoo ships with ESPHome pre-flashed and a working config ready to go. Adopt it into Home Assistant or ESPHome, customise over the air, and you're done.

No cloud. No app. No subscription. Ever.

Everything the Deta smart switch should have been.

The Deta smart switch looks the part, but it phones home to do it. Cloud dependent, app required, no way to extend it, and no way to know what data is leaving your wall. SwitchRoo uses the same housing you already know, and none of the compromises.

Remote access and dashboards require your local network or a Home Assistant remote access setup. No third party cloud involved either way.

Deta Smart Switch

Phones home to China every time you flick a switch

Every button press is a round trip to a server you don't control. What data is leaving your home? Nobody really knows.

SwitchRoo

No cloud, no pings to China, no subscription

Your switch, your network, your data. Once it's on your wall it answers to you and nobody else.

Deta Smart Switch

Cloud goes down, switch goes dumb

When their servers have a bad day, your automations stop working. You're at the mercy of someone else's uptime.

SwitchRoo

Works without internet, switching never fails

Local switching works even if your internet is down. ESPHome runs on the device itself, so local automations, state machines, and motion-triggered lighting all keep working.

Deta Smart Switch

Always-on blue LEDs you can't dim or turn off

A small thing that drives you crazy every single day. Your switch, your wall, your rules - except they're not.

SwitchRoo

RGBW LEDs, fully customisable

Set the colour, brightness, and behaviour to whatever you want. Or turn them off entirely. Finally.

Deta Smart Switch

No presence detection, ever

The hardware will never support it. It was designed to switch lights, full stop.

SwitchRoo

mmWave presence detection (add-on)

True presence detection built into your switch plate. No separate sensor, no extra wall clutter, no extra wiring.

Deta Smart Switch

Useless without the app

No app, no control. Guests, family members, anyone without the app is stuck using it as a dumb switch.

SwitchRoo

Fully local control, always

Every command stays on your network. No internet required, no servers involved, no middleman between you and your switch.

Deta Smart Switch

No way to extend or customise it

What you bought is what you get, forever. No firmware updates that add features, no community improvements.

SwitchRoo

Your hardware, your logic

Want a state machine that triggers on presence, changes LED colour based on room occupancy, flashes when lights are about to auto turn off or dims at night? You can. ESPHome runs on the device, the logic lives on the switch, and none of it needs the cloud or even Home Assistant to function.

Deta Smart Switch

Locked to the Deta ecosystem

Migrate to a different platform? Start over. Every switch, every wall plate, every dollar spent.

SwitchRoo

Open platform, not a dead end

MakerRoo could disappear tomorrow and your switches would keep working. The community owns this, not us.

SwitchRoo

ESPHome native, Home Assistant ready

Built for the platforms you already use. Adopt it in seconds, no custom components or workarounds needed.

SwitchRoo

Ready-to-use ESPHome config included

Ships pre-flashed and ready to adopt. You don't need to write a single line of YAML if you don't want to.

SwitchRoo

Matter, Thread and Zigbee hardware ready

The ESP32-C6 has the hardware. When software support catches up, your switch is already ready for whatever comes next.

SwitchRoo

OTA updates, flash your own firmware anytime

Change your mind about how it works? Update it over the air. No physical access, no screwdrivers required.

Variants

3 gang
2 gang (soon)
1 gang (soon)
4 gang (roadmap)

SwitchRoo launches with a 3 gang board, compatible with 3 gang Bunnings Deta touch switch housings. 1 and 2 gang variants will follow shortly after launch, and 4 is on the roadmap.

Options at checkout:

  • mmWave presence detection (add-on)
  • Header pin position (left or right)

Not sure which pin position you need or whether mmWave is right for you? The docs will have guides to help you decide.

What's next

Temperature and humidity sensing and a buzzer are examples of add-ons we're considering for future releases. Got a feature you'd like to see? Let us know in the Discord.

SwitchRoo is a light switch today, but the ESP32-C6 platform it runs on is capable of a lot more. And the housing it sits in? That's the real insight.

These Bunnings switch housings are everywhere. Electricians know how to install them, they fit standard wall boxes, and they're at every Bunnings in the country. Once you have a low-voltage PCB platform that drops into that form factor, it stops being just a light switch. It becomes a standardised mounting point for whatever human interface you want around your home - touchscreens, e-ink displays, sensor panels, room controllers.

Want a small control panel next to your existing switches? Same housing, same installation process, different board.

The stock switch is a dead end.
SwitchRoo is a platform.
