Water Heater Temperature App

With seven people in the house it would be nice to have a web app that told us when there was enough hot water for a decent shower. Hence this project.

We will use a DS18B20 sensor (or something similar) connected to the Pi that monitors the water heater vibrations. Then we put up a red/yellow/green panel at a web address only the family knows. 🙂 Here is a more detailed tutorial.

So far the family hasn’t shown any interest so this may be on the back burner for a while.
