Through HV Kapitali OÜ, it builds practical apps and automation projects shaped by real needs: Heikki develops and uses the tools himself. The brand’s work spans energy, smart homes and web applications, with a focus on useful technology that works intuitively.

Its energy services bring together solar panels, home batteries and electric vehicles, using energy prices and automation to optimise consumption. Smart-home projects use Home Assistant, sensors and integrations to manage systems locally, including energy arbitrage, photovoltaic output control, forecasting and participation in balancing and capacity markets. The site also highlights connections between Deye equipment, Home Assistant and Tesla.

For web, vibetec creates websites and applications designed to be straightforward to use, with data pre-filled where appropriate. Examples include accommodation websites, a SaaS platform for accommodation providers and a community mapping tool. Prospective clients can explore services and pricing or book a free 25-minute Google Meet conversation to discuss an MVP project.
