Hildebrand Glow, Home Assistant and MQTT - Getting visibility into my energy data

Posted on Wednesday October 13, 2021 • Read time 20 minutes

Since Home Assistant announced energy monitoring was being added, I've been super interested in what sort of data I could get out of my energy system. We have nothing fancy here. Just fairly standard dual-fuel (electricity and gas) system provided by the grid with a smart meter. No solar panels or batteries or returning power to the grid.

Understanding MQTT: My Notes

Posted on Saturday August 28, 2021 • Read time 10 minutes

Home Assistant Part 1: Setup and Initial Configuration

Posted on Friday May 29, 2020 • Read time 25 minutes

This series of blog posts about Home Assistant will document and detail the setup I'm using, as well as linking to the devices, parts and equipment I'm using to make what I'm doing possible.
