From sensor configuration to complete IoT dashboards — ready-made packages with transparent pricing. All prices are final. No VAT charged per § 19 UStG (small business regulation).
New here? Start low-risk with the 39€ Code Check — small job, fast result, take it from there.
All packages deliver software only (firmware, configuration, code) — I do not sell hardware. Required components are only linked, you buy them yourself. Enclosures on request.
Custom project? Your project doesn't fit any package? No problem — use my Project Configurator and describe your project. Or write me directly at bastelix-lab@gmx.com.
