This is my first Raspberry Pi project to monitor temps and efficency of my house ventilation system (Vaillant RecoVair 350). Baiscally I use 5 temperature sensor and a Raspi to send data to Microsoft Azure IoT hub. From there the Azure Streamanalytics calculates the efficency and forwards to Microsoft streaming dataset where PowerBI shows up the data on a dashboard. Additionally I add the CPU temperature and and a virtuell GPS position by reading the ISS position on each sample. Samples where send each minute by using cron job.
