Lots of temperature data is available. The collection points are scattered throughout the house.
The probes are in:
- the attic
- the basement
- the return and supply air ducts
- the freon lines
- the input and output lines to the water heater
- the input and output lines of the Ground Source Heat Pump
- the wine cellar (temperature and humidity)
I'd also like to measure the amount of water used from my well. I could fairly easily measure the run time of the well pump, but would rather measure the volume of water. I've installed a water meter on the output of the pressure tank and hope to get it instrumented RSN.
I also have a Tempest weather station that feeds data to Weather Underground and to HA.
