Monitoring system for floor heating system circuits. This specific case is created to monitor the heat exchanger circuits for 4 heating loops.
This system is designed to monitor several different loops in a floor heating system using a heat exchanger. The measured data is published to a Home Assistant using an MQTT broker.
The system is built arround 1-wire temperature sensor DS18B20 connected to a Raspberry Pi with 1-wire setup as default on GPIO 4.
My specific project will be using 10 DS18B20 sensors to monitor my total 4 loops + supply/return on the heat exchanger. They are connected as shown in this picture:
Currently the system uses a standard hardcoded setup with fixed Mac Addresses for all sensors. In future expansions the intention is to create this list dynamically and storing it in a config JSON file.
