Smart products with real customer value

Our software combines real customer value with innovative solutions

We develop custom software for smart home, electronic devices, and building technology.

Are your products ready for the digital future?

Digital solutions drive market success, but user-centered software requires more than just technical expertise – it demands a deep understanding of your industry, products, and customers. We support you with expertise in consumer electronics, smart home, and building technology. Lacking software experience or resources in your company? We develop tailored solutions that inspire. Let’s rethink your product digitally – with user-centered methods and insights that propel you forward in the market.

All household appliances digitally connected

Miele App Smart Home

As a pioneer and industry leader, Miele had a vision of the connected smart home from an early stage. When the decision was made in 2019 to relaunch the app, slashwhy was commissioned as a development partner. With the Miele app, it was possible to develop a digital communication channel to match the physical Miele product world and thus create a seamless, inspiring customer experience.

Software that fits your users

Starting points for a smart home

Whether it's developing smart control systems, integrating into existing smart home ecosystems, or creating device software—we are your partner in identifying trends, understanding challenges, and shaping the future together.

Select a category and explore our use cases.

As accompanying mobile or web applications, Smart Home Apps enhance household appliances such as washing machines, ovens or fully automatic coffee machines with smart features such as convenient remote control, status messages or personalised recipe recommendations. We develop user-centred applications that connect seamlessly to the device software: from app development to Bluetooth and Wi-Fi interfaces and cloud backends (AWS, Azure) to UX & UI design. This results in scalable solutions that enable brand differentiation and can also be integrated into future generations of devices.

Today's modern household appliances adapt automatically to environmental conditions, respond dynamically to loads and recognise materials: sensors provide real-time data, while adaptive algorithms automatically adjust programme sequences, speeds and heating profiles. The result is less effort required to operate the appliance, higher energy efficiency and a noticeably intelligent user experience. We develop the complete software stack on the device – from embedded firmware, sensor integration and status logic to test frameworks and secure update capability. This creates a future-proof software basis that makes current and future product generations performant and maintainable.

Whether high-resolution touch displays, voice or gesture control – modern, accessible HMIs offer users a wide range of interaction options and convey brand identity directly on the device. We develop intuitive user interfaces that integrate seamlessly with companion apps, both visually and functionally, creating a consistent experience across all touchpoints. Based on UX research, brand-compliant UX & UI design and reusable design systems, we significantly reduce time to market. With the help of powerful embedded GUI frameworks such as Qt, LVGL or Storyboard, we create future-proof interfaces that inspire users.

Home appliances only become truly smart when they integrate seamlessly with Apple Home, Google Home or Amazon Alexa and can be controlled by voice command. We connect washing machines, ovens and coffee machines directly to the leading smart home platforms via open APIs, develop the appropriate voice skills and ensure smooth cloud connectivity. This gives end users maximum convenience, while manufacturers increase their visibility in the ecosystem and future-proof their product lines. We take care of UX design, platform-compatible voice skills and API design, and ensure stable, future-proof connectivity so that every device can be reliably integrated into scenes, automations and routines.

Cloud platforms form the backbone of connected household appliances: they collect telemetry data, orchestrate automation rules and offer services such as firmware rollouts, push notifications and usage analyses. We develop scalable cloud solutions based on AWS, Azure or Kubernetes architectures – including powerful device interfaces (MQTT, REST), event processing, data lakes and microservices. With well-thought-out UX & UI concepts for web portals and dashboards, we create transparency for manufacturers regarding device statuses and interaction patterns and enable the delivery of new features in real time. The result is a future-proof platform that increases convenience, differentiates brands and grows flexibly with additional device lines.

On one hand, you need a very structured approach, otherwise, it ends in chaos. On the other hand, you need to be flexible enough to handle such a ‘fuzzy’ project – and you need people who can deal with that.”
