Thomas Ihmann developed and integrated a new heating system template for the evcc-io/evcc repository, enabling seamless interaction with Buderus, Bosch, and Junkers devices through HTTP API calls. He focused on configuration management and embedded systems, using yaml to define templates that support setting and retrieving operating modes and temperature data, including frost protection and immediate control. Thomas also refactored the emsesp getmode logic, simplifying mode determination to ensure accurate state identification based on SG1 and SG4 inputs. His work laid a foundation for future template extensions, improving maintainability and robustness in the system’s configuration and mode handling processes.
