Been tinkering with HA for a while and kept running into the same problem: most beginner guides either skip important steps or assume Linux knowledge. So I put together a full series covering everything from zero.

Here's what's in each part:

1. What is Home Assistant and why run it locally? – cloud vs local explained, what you can control: https://youtu.be/zSZIDPAJM7o

2. Installing HA on an old PC – full HAOS install on any x86 machine, free, takes about 20 minutes: https://youtu.be/ON_o-7OnsvY

3. First setup: network, users and your first dashboard – getting from a blank install to something actually usable: https://youtu.be/muOjMoSu8gM

4. Top 10 free integrations every beginner should add – weather, Google Calendar, mobile app, energy monitoring and more: https://youtu.be/MwfbYNkBtrA

5. Your first 5 automations – time-based, presence detection, sunrise/sunset, all done with the visual editor (no YAML required): https://youtu.be/wvGBYJbT0SE

6. Connecting smart plugs and lights without cloud – Tasmota, ESPHome, Zigbee2MQTT and why keeping it local matters: https://youtu.be/QQii9H5IsK8

7. Building a good-looking dashboard from scratch – Mushroom cards, custom layouts, dark mode: https://youtu.be/qUOar06yXLI

Everything is free on YouTube. Happy to answer questions if anything is unclear — this is the kind of series I wish had existed when I started.

Prices in SA make home labbing feel out of reach, but I pulled this together for under R3k using second-hand business hardware. Here's the full breakdown so it's actually useful:

**The Hardware**

- Used Dell/HP SFF business PC (OptiPlex/EliteDesk) sourced from Gumtree/Takealot — R1,500–R1,800

- RAM upgrade: 8GB → 16GB (2x8GB DDR4) — ~R450

- Additional SSD for VM storage — ~R350

- **Total: ~R2,450** (leaves ~R550 buffer in the R3k budget)

Why SFF business PCs? They're dead quiet, pull ~35W idle, have ECC-adjacent reliability, and Gumtree is flooded with them from corporate refreshes. An i5-6500/i7-6700 handles 4–5 concurrent VMs without complaint.

**The Software Stack (everything free)**

Hypervisor:

- Proxmox VE — bare-metal hypervisor, enterprise-grade, completely free for home use. Web UI makes VM management easy.

Guest VMs:

- Windows Server 2022 Evaluation (180-day free licence) — running Active Directory, DNS, DHCP

- pfSense — dedicated firewall/router VM with VLAN support

- Ubuntu Server 22.04 — general Linux lab, Docker host

- Rocky Linux 9 — CompTIA Network+ exam prep (used in a lot of study guides)

Tools running inside:

- Zabbix for network monitoring

- Docker + Portainer for container management

- SSH everywhere, Cockpit for system dashboards

**What You Can Actually Practice**

- AD domain setup, GPO, user/group management

- VLAN segmentation on a managed switch

- Firewall rules, NAT, site-to-site basics with pfSense

- Docker basics — containers, volumes, networking

- Python automation scripts against the lab environment

- Backup strategies (rsync, Proxmox snapshots)

The whole point was proving you don't need a rack or server hardware. A R1,500 second-hand office PC is more than enough to run a serious lab.

Happy to answer questions — especially from others in SA where import costs and shipping make new gear painful.
