IoT that indeed works.
From microcontrollers to enclosures and apps—custom hardware, firmware, and software, made in Eastern Switzerland.
You need an IoT product without the supply chain headaches. We develop hardware, firmware, and apps under one roof in Widnau (SG). Pilot in 4-6 weeks, full product in 6-9 months—all from the Swiss Rheintal.

Three arguments to convince SMEs
Data stays with you
On your own hardware, on-premises. No data leakage, compliant with FADP and GDPR.
$0 token cost
No cloud dependency, no API bill at month’s end. One-time investment instead of OPEX.
Productive in 6-12 weeks
From project request to pilot rollout. We use tried-and-tested components, no research project.
months of waiting or 6 weeks of building – you decide.
GrowDoser full product: custom housing (3D printing/CNC), proprietary firmware, dedicated app, GSM backend, no third-party cloud.
From the field
Three projects, three fully developed products.
🌱 Full product
GrowDoser
In-house product TB-Software (2021-2025)
Task: Manual nutrient dosing for plants is error-prone and time-consuming.
Result Fully automatic dosing system with its own housing, firmware, Windows panel, Android app, and GSM connectivity.

🌡️ Sensor technology
Weather station + plant monitor
Own products / pilot installations
Task: Standard sensors do not have their own database and cannot be expanded.
Result Sensors based on ESP8266/ESP32 with local display, MQTT integration, and full data access.

🛡️ Firmware
IPFire for Banana Pi R3
Custom firmware build
Task: Standard routers don’t meet special requirements; custom firmware was unavailable for the Banana Pi R3.
Result Complete port of IPFire to a new hardware platform, operational in a production environment.

Frequently asked questions about IoT projects
What does an IoT pilot cost?
Pure sensor solution with app connectivity 10-25 k CHF Development. Full product with housing design, firmware, app, and cloud backend: 0-120k CHF, depending on quantity and certification needs. Exact estimate provided in briefing.
Do you only develop software or also real hardware?
Both. We’ve developed our own products with 3D-printed and CNC-milled enclosures, designed custom circuit boards, and written firmware in C/C++ directly for ATMEGA328P, ESP8266, and ESP32. For GrowDoser, we built the entire stack ourselves, from SolidWorks enclosure CAD to the Android app.
What about mobile network coverage?
We have SIM800L modules in productive use (GrowDoser uses them for autonomous locations without Wi-Fi). LoRa and Wi-Fi are also standard options. For industrial customers, we offer wired solutions via Ethernet/Modbus.
Where are the data stored? With you, in the cloud, or with me?
By default on a server of your choice. Optionally encrypted to our Swiss hosting or fully on-premises. We only use US cloud providers if you explicitly request it, usually not for IoT data due to GDPR.
Who manufactures the hardware in quantities?
We print/mill prototypes on-site in Widnau (Rheintal). For series production, we have partners across Switzerland, Vorarlberg, and southern Germany; we coordinate manufacturing, BOM management, and quality control for you.
What we build with
Hardware idea from Rheintal, from concept to production?
Send us an email or initiate a non-binding briefing at our office in Widnau (SG). Within 24 hours, you’ll receive an initial assessment from Timo Böhme himself. On-site service available in the Ostschweiz region and nationwide across Switzerland.
