Use Smart Energy Meter with Home Assistant

The Dutch Government is aiming on providing smart meters to every household before Q4 2020. All the smart meters need to comply to DSMR (Dutch Smart Meter Requirements). DSMR allows us to read data from the smart meter by using a cable. In this guide, I will explain how I got this to work with Home Assistant.

Configuring the new Home Assistant Hass.io 64-bit image on a Raspberry Pi 3 Model B+

My last blog post was all about getting Hass.io (or HassIO) installed on the new Raspberry Pi 3 Model B+. This guide starts right where we left off: configuring Home Assistant to work with the configuration files we already have from Home Assistant running on Raspbian. Below are the steps I took in a nutshell.

  • Install and open the Configurator Add-on on Hass.io to make sure you can always open the web UI to change your configurations.
  • Create a snapshot so you can always go back to this point in time.
  • Cut/paste the BaseURL and SSL settings from the configuration.yaml on your old Pi to the new configuration.yaml on your new Pi by using the Configurator add-on. Make sure that you have an SSH session open to the old Pi on the IP address of the old Pi, so you can still copy/paste the contents of various configurations. Also stop the Home Assistant service on your old Raspberry Pi and change any port forwarding rules in your firewall or DNS settings. (Depending on your old setup)
  • Got your Home Assistant ready under the original URL? Create a new snapshot, just to be sure.
  • Start copying the contents of your configuration.yaml and other relevant YAML configurations by grabbing it from SSH and pasting it in the Configurator Add-on. I was surprised to see that all the modules I’ve used before on Raspbian are working fine on Hass.io! So don’t worry too much about that.
  • Go to your Hass.io URL and confirm the dashboard is back to where it was before.

Let me know if this guide helped you out!

Cheers!

Use PowerShell DSC and Azure Automation to Create an Active Directory Domain

Because of the recent domain change of my blog, I decided to completely start over again with my lab in Azure. I’ve been working with Desired State Configuration Configs in Azure for quite a few years, but never used them for my own lab environment. It felt a bit overkill to do that, but now I wanted to start over and do everything right.

This step-by-step installation guide explains how to create a DSC Configuration in Azure Automation and how to apply this on your domain controller in Azure.

Installing the new Home Assistant Hass.IO 64-bit image on a Raspberry Pi 3 Model B+

Home Assistant recently announced a brand new image of Hass.IO running on HassOS. I instantly ordered a new Raspberry Pi 3 Model B+ to replace my older Raspberry Pi Model B, which was running Raspbian and Home Assistant. The guide below helps you with installing your new Hass.IO instance!
