  • Replacing ISY with Home Assistant – Part 2 – A New Home

    This is the continuation of a short series on transitioning away from the ISY using Home Assistant. Getting Started, again As I mentioned in my previous post, my plan is to run my new instance of Home Assistant in parallel with my old instance and transfer functionality in pieces. This should allow me to minimize…

  • Replacing ISY with Home Assistant – Part 1a – Transition Planning

    This is the continuation of a short series on transitioning away from the ISY using Home Assistant. The Experiment I mentioned in my previous post that I had ordered some parts to run an experiment with my PowerLinc Modem (PLM). I needed to determine that I could use my existing PLM (an Insteon 2413S, which…

  • Collecting WCF Telemetry with Application Insights

    I got pulled back in to diagnosing performance issues on an old friend, and it lead me into some dead code with a chance for resuscitation. Trouble with the WCF One of our applications has a set of WCF Services that serve the client. We had not instrumented them manually for performance metrics, although we…

  • Maturing my Grafana setup

    I may have lost some dashboards and configuration recently, and it got me thinking about how to mature my Grafana setup for better persistence. Initial Setup When I first got Grafana running, it was based on the packaged Grafana Helm chart. As such, my Grafana instance was using SQLite database file stored in the persistent…

  • Snakes… Why Did It Have To Be Snakes?

    What seems like ages ago, I wrote some Python scripts to keep an eye on my home lab. What I did not realize is that little introduction to Python would help me dive into the wonderful world of ETL (or ELT, more on that later). Manage By Numbers I love numbers. Pick your favorite personality…

  • Installing Minio on a Synology Diskstation with Nginx SSL

    In an effort to get rid of a virtual machine on my hypervisor, I wanted to move my Minio instance to my Synology. Keeping the storage interface close to the storage container helps with latency and is, well, one less thing I have to worry about in my home lab. There are a few guides…

  • Using SonarCloud for Open Source

    My last few posts have centered around adding some code linting and analysis to C# projects. Most of this has been to identify some standards and best practices for my current position. During this research, I came across SonarCloud, which is Sonarqube’s hosted instance. SonarCloud is free for open source projects, and given the breadth…

  • Tech Tips – Adding Linting to C# Projects

    Among the Javascript/Typescript community, ESlint and Prettier are very popular ways to enforce some standards and formatting within your code. In trying to find similar functionality for C#, I did not find anything as ubiquitous as ESLint/Prettier, but there are some front runners. Roslyn Analyzers and Dotnet Format John Reilly has a great post on…

  • Deprecating Microsoft Teams Notifications

    My first “owned” open source project was a TeamCity plugin to send notifications to Microsoft Teams based on build notifications in Teamcity. It was based on a similar TeamCity plugin for Slack. Why? Well, out of necessity. Professionally, we were migrating to using MS Teams, and we wanted functionality to post messages when builds failed/succeeded.…

  • Pulling metrics from Home Assistant into Prometheus

    I have setup an instance of Home Assistant as the easiest front end for interacting with my home automation setup. While I am using the Universal Devices ISY994 as the primary communication hub for my Insteon devices, Home Assistant provides a much nicer interface for my family, including a great mobile app for them to…
