I want to integrate my new Viessmann Vitovalor 300-P fuel cell heating into my home automation. For this, I use the Optolink interface, vcontrold from the openv community, and create my own configuration files from several sources.
To create a lamp with adjustable color temperature and brightness, I use a warm/cold white dual LED strip, an ATtiny45 MCU with N-channel MOSFETs and two adjustable resistors. This article contains the hardware and software setup. The title image of this blog shows the project.
