Summaries are not the original full articles. ## My Home Lab, V2 DevFeed: [My Home Lab, V2]() Original publisher: [Read original article]() Author: EduuhMuraya Published: 2026-08-17T00:00:00Z Content type: article Language: en Sources: [EduuhMuraya]() Topics: [Homelab](), [Home Assistant](), [Network](), [Firewall](), [Internet of things](), [MQTT](), [Server](), [Kubernetes]() Tags: [firewall](), [home-lab](), [infrastructure](), [kubernetes](), [network](), [networks](), [proxmox](), [smart-home](), [usb]() ### AI overview An updated home lab replaces a multi-node Kubernetes setup with one mini PC running Proxmox. The article covers segmented networks enforced by OPNsense, firewall testing from within each segment, and a solar-power system integrated with Home Assistant through USB and MQTT. It also describes load-shedding and shutdown safeguards during battery depletion. ### Source excerpt The Kubernetes cluster is gone. One mini PC runs the whole house now: four network segments, a solar inverter Home Assistant can act on, and a guard that shuts the servers down before the battery does. ## The Checks That Lied DevFeed: [The Checks That Lied]() Original publisher: [Read original article]() Author: EduuhMuraya Published: 2026-08-14T00:00:00Z Content type: article Language: en Sources: [EduuhMuraya]() Topics: [networking](), [Firewall](), [Routing (disambiguation)](), [Networks](), [Pi-hole]() Tags: [automation](), [dns](), [firewall](), [infrastructure](), [network](), [opnsense](), [proxmox](), [routing](), [security](), [server](), [servers]() ### AI overview A home-network segmentation test produced misleading green results because the checks did not reliably measure the firewall or connectivity. The article describes routing around the firewall through a dual-homed Proxmox host and a DNS check that treated resolver failures as successful output. ### Source excerpt I segmented my network, wrote tests to prove it, and watched the tests pass while measuring nothing at all. Then the same disease turned up in my home automation, and left a freezer switched off for thirteen hours in a house full of green ticks. ## Wiring Home Assistant Into My Solar Inverter DevFeed: [Wiring Home Assistant Into My Solar Inverter]() Original publisher: [Read original article]() Author: EduuhMuraya Published: 2026-08-14T00:00:00Z Content type: article Language: en Sources: [EduuhMuraya]() Topics: [Home Assistant](), [MQTT](), [data](), [Document Object Model (DOM)](), [phoenix](), [servers]() Tags: [data](), [firewall](), [infrastructure](), [proxmox](), [raspberry-pi](), [smart-home](), [telemetry]() ### AI overview This article explains how to connect a Growatt solar inverter to Home Assistant through Solar Assistant and MQTT. It covers running Home Assistant as a Proxmox VM, troubleshooting Phoenix LiveView form state and an inactive MQTT publisher, and keeping the integration read-only. ### Source excerpt A Growatt inverter, a Raspberry Pi running Solar Assistant, and Home Assistant on Proxmox. Bridging them took an MQTT broker, a form that silently discarded everything I typed, and a decision to keep the link read-only. Then it stopped watching the house and started switching it off. ## Opnsense - Firewall DevFeed: [Opnsense - Firewall]() Original publisher: [Read original article]() Author: EduuhMuraya Published: 2026-03-04T00:00:00Z Content type: article Language: en Sources: [EduuhMuraya]() Topics: [Firewall](), [Internet of things](), [networking](), [configuration]() Tags: [dns](), [firewall](), [infrastructure](), [network](), [opnsense](), [policy](), [security]() ### AI overview An examination of the live OPNsense firewall rules used to isolate an IoT segment, including default-deny behavior, rule ordering, DNS access, firewall-address boundaries, and device-to-device blocking. ### Source excerpt The rules that seal my IoT segment, in the order they have to be written, and the two that look redundant until you understand what they are for. ## GitHub Actions Things I Wish I Knew Earlier DevFeed: [GitHub Actions Things I Wish I Knew Earlier]() Original publisher: [Read original article]() Author: EduuhMuraya Published: 2026-02-22T00:00:00Z Content type: tutorial Language: en Sources: [EduuhMuraya]() Topics: [GitHub Actions](), [CI/CD](), [GitHub](), [OpenID connect (OIDC)](), [Azure](), [ACR](), [Caching](), [Docker](), [Command-line interface]() Tags: [acr](), [azure](), [caching](), [ci-cd](), [cli](), [devops](), [docker](), [github](), [github-actions](), [oauth](), [secrets](), [workflow]() ### AI overview A practical guide to non-obvious GitHub Actions considerations when setting up CI/CD for a monorepo, covering matrix strategies, OIDC authentication, buildx credentials, registry caching, immutable image tags, and manual workflow triggers. ### Source excerpt Matrix strategies, OIDC auth, registry caching, and a few footguns I hit setting up CI/CD for a monorepo. ## Longhorn: distributed storage for my homelab DevFeed: [Longhorn: distributed storage for my homelab]() Original publisher: [Read original article]() Author: EduuhMuraya Published: 2026-02-22T00:00:00Z Content type: tutorial Language: en Sources: [EduuhMuraya]() Topics: [Homelab](), [Kubernetes](), [Replication](), [GitOps](), [configuration]() Tags: [declarative](), [distributed](), [gitops](), [homelab](), [infrastructure](), [kubernetes](), [replication](), [self-hosted](), [storage]() ### AI overview A practical account of using Longhorn as distributed block storage across a Kubernetes homelab. It covers replicated volumes, snapshots, incremental backups, disk tags for storage tiers, and declarative management with Flux, including recovery considerations when a node goes offline. ### Source excerpt How I use Longhorn for distributed block storage across my Kubernetes homelab. Replication, disk tags, GitOps management, and what happens when a node disappears for nine days. ## Pushing Docker Images to Azure Container Registry with GitHub Actions DevFeed: [Pushing Docker Images to Azure Container Registry with GitHub Actions]() Original publisher: [Read original article]() Author: EduuhMuraya Published: 2026-02-22T00:00:00Z Content type: tutorial Language: en Sources: [EduuhMuraya]() Topics: [ACR](), [Docker](), [GitHub Actions](), [OpenID connect (OIDC)](), [GitHub]() Tags: [acr](), [auth](), [azure](), [devops](), [docker](), [git](), [github](), [github-actions](), [images](), [secrets](), [workflow]() ### AI overview This tutorial explains how to build four Docker images from a monorepo and push them to Azure Container Registry with GitHub Actions. It covers Git SHA tagging, registry-layer caching, authentication setup, and why an OIDC-based approach failed with Docker buildx, leading to the use of GitHub-stored administrator credentials. ### Source excerpt Set up a GitHub Actions workflow to build and push Docker images to ACR.
