punktwissen: Elke Stangl and Sigi Proyer - physicists and professional tinkerers.
We program controllers by Technische Alternative for heating/solar systems. Speciality: Analysis of existing control systems and migration to UVR16x2. As IT freaks we support with monitoring, data analysis, and secure integration with the 'internet of things'.
We support do-it-yourself-ers with building a tailor-made heat pump system, and we program the system's bespoke control unit. Focus: Renovation, re-use of existing components.
punktwissen means: Technical information and vendor-agnostic consulting boiled down to the essentials. We believe it is imperative that you know and understand your systems in order to make informed decisions. Control logic must not be tucked away in a black-box.
punktwissen also means: Support at the neuralgic points of a project - when and only to the extent it is really needed.
