We love smart homes. You probably too :-) But why do we need to buy so many smart devices? Gateways, hubs, thermostats, motion detectors, air quality sensors, surveillance and security systems, voice assistants, intercoms, smart meters, light and shutter switches It's a huge waste of resources, time and money. That's why we invented SHPI – the smart home peripheral interface.

SHPI replaces multiple room devices in one integrated product.

SHPI is a open-source, programmable, wall-mounted device that you can use to keep track of everything that’s going on in your home, including temperature, barometric pressure, humidity, air quality, presence detection, and even electrical currents. The optional camera completes SHPI, making it a perfect surveillance system.

* depending on model and version.

Using integrated relays, SHPI can take direct control of up to three electrical loads, giving you complete oversight in your own home. SHPI is fully independent and can be used as a gateway to integrate different other devices in your smart home.

Finally, you can stop worrying about managing so many different devices! Instead, you’ll be managing everything, from the temperature in your home to your security system, through a single interface.

Replace Traditional Systems

Our system replaces convoluted HVAC controls, thermostats, and shutter switches, making them smart and giving you a whole load of other capabilities. We have designed SHPI as a drop-in replacement for your thermostat, light, and shutter switches. Using the touch screen, you can operate it easily, simply connecting over USB, WiFi, Bluetooth, or optional radio modules. Going beyond environmental controls, it’s also capable of motion detection, microphone security, and video security, signaling you whenever there’s a warning.

Open Source

We provide drivers and demo applications for an easy start in Python.

Designed for Makers

The and is powered by a Raspberry Pi Zero W and Arduino compatible ATmega 32u4 micro-controller, allowing everyone to build their own smart home applications based on SHPI. For a simple start, the Atmega comes with our firmware. Custom or customized software can be flashed on the ATmega using the Raspberry Pi. Flashing is possible on-the-fly during operation without hardware intervention. We also make SHPI highly customizable. With a little soldering, you can expand the functionality of SHPI for every use.
