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. I had no space in my condo, so I instead explored other options.
I came across the Emporia Vue2 and identified that it was running a standard ESP32 device and was easy to reflash with custom ESPHome firmware. ESPHome is an open-source framework for creating firmware to collect data from a variety of different sensors and publish it to MQTT/Home Assistant. This sounded perfect, so I ordered a Vue2 and here’s how I made it work.
Air—it’s invisible, I can’t see it, but I feel effects of it in so many ways, temperature, humidity, gas composition, but I lacked sensors to measure it. In this post, I walk through some different Air Quality sensors that I found and how I wired them up into a dashboard.
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.
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.
