In the previous post we looked at options available for water meters and how to interface them with a Raspberry Pi. In this post we will delve into the details and go through the steps to make the actual connection to the meter and set up the software. We’ll push the water flow rate to Home Assistant using MQTT as well as the amount of … Continue reading Water Metering Part 2
I’ve been interested in adding utility measurement features to my Home Assistant installation for over a year. After a number of tries, I finally have most of the functionality I set out to implement. My impetus for adding detailed utility measurement goes back to a quote by entrepreneur (and founder of GoDaddy) Bob Parsons, “Anything that is measured and watched, improves.” Now that I have … Continue reading Utility Measurement with Home Assistant

In preparation for designing a home energy monitoring system, I created a small project to measure and post data from the Netduino. The simplest circuit I could find consisted of a photocell and a resistor wired into one of the analog inputs. Every … Continue reading Sharing Data From the Netduino
