Read out the temperature of a heating device
- This script enables to read analog values (voltages representing temperatures) from a house heating device (e.g. Paradigma) with a raspi.
- The values are handed over to FHEM house automation for further processing and visualization (tracking of temperatures, solar income,...)
- Running Raspi
- Analog -> Digital Device (here: MCP3008 ADC device using the SPI Bus)
- wiring to heating system
- running FHEM for house automation -> calling python script out of fhem in recurring time steps...
- Measuring the voltages and calculating back the temperatures
- Voltage divider has to be known or to be evalutated while measureing some temperature/voltage tuples
