Testimonials
People already living in a smart home

Residential customerUrbanova · São José dos Campos

Frequently asked questions
The questions we hear most
No. The devices are designed for the 4x2 in wall box already behind your current switch and reuse the same wiring. In most cases an electrician completes the swap in a few minutes per point, with no remodelling and no mess.
No. The physical touch keeps working exactly like an ordinary switch. On top of that, the app has a local mode: as long as your phone is on the same Wi-Fi network, you keep full control even without internet access. The cloud is only needed for remote control away from home and for voice commands.
Yes, with both. We have the official Coisas Espertas SmartHome skill published on Amazon and a native Google Assistant integration. Download the app, create your account, add the device and link the account once. After that the assistants recognise your devices on their own.
No. Each device connects directly to your 2.4 GHz Wi-Fi network, with no hub, no gateway and no mandatory subscription. That lets you start with a single point and expand gradually, at your own pace and within your budget.
Yes. Our devices are homologated by Anatel and follow the Brazilian electrical standard. Coisas Espertas is a brand of SESIS, an engineering company based in São José dos Campos, Brazil, where the hardware, the firmware and the cloud platform are all developed.
The line comes in 1, 2, 3, 4 and 6 gang versions, and each key controls an independent circuit. There is also a virtual 3 way feature that lets you command the same light from two different places without pulling new wire, which is ideal for hallways, staircases and bedrooms.
We deliver automation projects in São José dos Campos and across the Paraíba Valley with our own team and accredited partners. Devices ship anywhere in Brazil and can be installed by any electrician you trust. Get in touch and we will look at your case.
Communication between the device, the app and our servers is encrypted, and access to your home depends on your personal account. We process personal data under the Brazilian LGPD. You can check exactly what we collect, why and for how long in our Privacy Policy.
