Local Energy Monitoring using the Emporia Vue 2

This article is part of the Home Energy Monitoring series.

I’ve previously explored the world of home energy monitoring systems and in the past arrived at using the Brultech GreenEye Monitor for a project in a friend’s house. It had the advantage of being local out-of-the-box and had a wide range of compact CTs that made fitting the electronics in the breaker box a lot easier, but it had one flaw that made it not suitable for my condo. It had to be mounted outside the breaker box with wires running into the box.

Visualizing Home Energy Usage in InfluxDB and Home Assistant

In part 4 of this series on home energy monitoring, we setup InfluxDB to store and visualize Home Assistant energy monitoring data.

In previous posts in this series, I walked through how to get data flowing into Home Assistant.

In this post, we’ll get it flowing into InfluxDB for long-term retention.

Accurate, Local Home Energy Monitoring: Part 3 – Software Config

In the previous post in this series, I selected an energy monitoring system that is purely local based (no cloud), integrates into the breaker box, and showed how to connect it to the network and configure the size of each circuit. In this post, I’ll show how to connect the BrulTech GreenEye Energy Monitor to HomeAssistant and create some useful monitoring dashboards. GreenEye Monitor Firmware While trying to connect my monitor to Home Assistant, I came across a firmware bug in the GreenEye Monitor and found a forum thread that Brultech had a bug with their packet formats which has been fixed in firmware version 5.

Accurate, Local Home Energy Monitoring: Part 2 - Network Config

This post continues from the previous post in the series where I walked through the decision process on what energy monitor system to use and how to install Brultech GEM Monitor. I ended with the hardware physically installed and all Current Transformers (CTs) connected. In this post, I continue from that point and walk through the network and software configuration defining each circuit size. Network Configuration First, connect the device to the network (I’m using Ethernet) and ensure it’s turned on.

Accurate, Local Home Energy Monitoring: Part 1 - Hardware

Ever wondered where the energy is going in your house and know exactly when and which circuit is consuming the most electricity? How much is your air conditioning unit costing you each month in kWh? Home energy monitors are devices that you can use to monitor how much energy you’re using at any given point in time. You can use them to figure out how much each device or circuit you’re using overnight vs the day.
