We recently moved the twins into their own bedrooms, after sharing a room for nine years — it was finally time for some privacy 🙂

With their own rooms; they also got their own computers — a life long dream 😉 Those computers needs network, proper network, not Wi-Fi.

In November last year — I started building a DIY security alarm system, using a Raspberry Pi as the controller. My plan was to make a self-sustained system, using proper alarm hardware — like PIR sensors and sirens.

Integration with Home Assistant would be an add-on, not a requirement. I wanted the system to be as redundant and fault-tolerant as I could make it.

This is a pretty long story, with some twists and turns — let’s get into it 👇

We recently put up a wall in our previous family/play room — to make another bedroom, with a hallway outside. I might want an access point in that hallway at some point.

So I repurposed a telephone outlet and conduit, to run a CAT6 cable from the hallway down to the patch panel in the basement.

I stumbled onto NextDNS recently — it’s like a cloud hosted Pi-hole. I tried it for a few days, but this post isn’t about that.

Reading about the different block lists in NextDNS, and digging deeper into DNS ad blocking gave me motivation to change my current setup — and that is what this post is about 🙂

Searching for a tool to keep track of IP addresses; I stumbled onto Netbox — and was blown away by what it could do 🤯 I could put everything there: racks, servers, patch panels, Wi-Fi access points, power distribution, network runs. Everything!

With the electricity prices we’ve seen in Europe lately — I wanted to see if we could reduce our energy consumption. I’m specifically looking at “wasted” energy, meaning usage we can reduce without even noticing it.

Having a central place to view or search through server logs is awesome. I’ve used Graylog in the past, but I’ve always felt it was a bit cumbersome to set up and use — and it felt overkill for my need.

Instead I gave Grafana Loki and Promtail a try 👇

Controlling my Komfovent balanced ventilation system through Home Assistant — opens up a world of possibilities.

Here are three automations I use to make the system a bit smarter 🙂

Mona needed more places to plant her flowers, so I built her some planter boxes — using impregnated wood and lining the inside with landscape fabric.

The Unifi UAP-AC-M access point in my garage stopped working a few weeks ago. Or, the device didn’t stop working, it still showed up in the Unifi controller and I could ping it. But it stopped providing Wi-Fi connectivity — my phone connected, but got no network access…

I remembered experiencing this before — the VLANs for user and guest Wi-Fi wasn’t allowed through the D-Link switch. I had simply not configured them, but why was it failing now?

Trying to log into the switch — I found that it no longer got an IP from the DHCP server. By all accounts; it looked like the switch had been reset.
