We develop the app and cloud side of smart home products – for manufacturers and brands that want to offer a reliable, user-friendly experience.
Smart Home Software
Smart home products need solid software: an app for setup and control, a backend for devices and updates, and secure links (BLE, WiFi, MQTT, Matter). We build for iOS and Android, use EU cloud when needed for GDPR and design for scale and long-term care. Your product can stand out through ease of use and reliability.
Manufacturers and brands that offer connected home products – lighting, heating, sensors, appliances – rely on the app and cloud experience as much as on the hardware. We develop the software side: mobile apps for setup and control, cloud backends for device management and over-the-air updates, and integration with common protocols such as BLE, WiFi and Matter. The result is a cohesive experience that works reliably and stays maintainable for years.
Data protection and EU hosting are standard for us when personal or usage data is involved. We design for GDPR from the start so your product is compliant in European markets. Analytics and diagnostics can be built in a privacy-preserving way so you get the insights you need without compromising user trust. OTA updates keep devices secure and enable new features without recalls or manual updates.
We support smart home projects from concept through to launch and beyond. That includes architecture design, app and backend development, and ongoing maintenance and feature updates. Our team is based in Germany and works with manufacturers and brands across Europe. If you have a smart home product in development or want to improve an existing app and backend, we are happy to discuss your requirements in a free initial consultation.
“Commercial smart-building projects often fail at Wi‑Fi boundaries—we plan mesh or edge before ordering hardware.”
Thorsten Frieling, Senior Developer & Project Manager, Groenewold IT Solutions
Smart home is won or lost in onboarding, reliability and updateability. If you are comparing what you have read to your current firmware and app roadmap, a focused call helps define the minimum lovable product path—protocol mix, device management, analytics and long-term support—before you commit hardware and app budgets.
