Homelab

In the next few posts, I’m going to document how to set up Home Assistant (HA) from scratch. We’re going to want to protect the admin UI interfaces for HA and its support services with SSL, and add authentication to services that don’t provide it themselves. We’re going to do this with Nginx Proxy Manager because it has built in support for using LetsEncrypt to obtain free SSL certificates, supports adding authentication to services that don’t do it themselves, and is overall easy to use. Before I start writing more Home Assitant articles, let’s set up a SSL proxy server to keep everything secure. ...

Some of my posts assume that the user already has ESPHome installed, so I’m documenting how to install it here so I don’t have to repeat it everywhere. ...

Just got an Orange Pi 5. I couldn’t find a simple set of instructions on how to boot it off the M.2 NVMe slot, so I’m documenting it here. ...

I’ve been backing my homelab up with duplicacy (See Backing Up the Cluster Using Duplicacy), but I’m fed up with it returning a 0 exit code even if there’s a problem with the backup. This makes me have to do a lot of annoying rummaging through log output to be sure that a backup actually worked, so I decided to switch to restic. In this blog entry, I’m going to explain how to create a jail in TrueNAS, mount directories you want to back up into the jail, install restic, and how to use it to back up to Backblaze b2. ...

TL;DR - SMR drives can take thirteen to sixteen times as long to resilver in your ZFS raid than CMR drives. If they even succeed. This wouldn’t be a big deal, except that Western Digital started using SMR technology in their WD-Red drives that are marketed toward SOHO and small business raid, without any warnings about the RAID performance implications. I got lucky when I bought my last batch of Reds, they were all CMR, but it was pure luck - I bought them based on Western Digital’s reputation and because I’ve seen multiple NAS vendors recommend WD-REDs in the past. ...

I wanted to set up a security camera outside, but I didn’t want to be dependent on an outside cloud service - if my internet goes out, I don’t want to lose my ability to record video. Wyze cameras are nice and cheap, and you can reflash them to support RTSP in addition to streaming to the Wyze cloud. ...

I’ve got an old HP laser printer in my basement. We barely print 10 pages a month between the two of us, so we only turn it on when we’re going to print. That’s a hassle though, because inevitably we forget to shut it off sometimes and it stays on overnight or even for days, and while it has a powersave mode, the 4050N is so old that even that burns a good amount of power. Enter Home Assistant. ...

I have an old HP 4050N. For a variety of reasons, I want to have it behind a print server instead of having my laptops print directly to it. Here’s how I set that up. ...

Sending notifications from Home Assistant via Twilio SMS I got a post published at work about How to Receive Alerts from Home Assistant with Twilio SMS, so I won’t replicate it here. TL;DR - It is super easy to send SMS messages via Twilio SMS with curl. Update: I wrote another article, Use PagerDuty with Home Assistant this time for using PagerDuty which allows automatically de-duping notifications.

I wanted a machine with more memory to be the master node for my ARM k3s cluster. I had an Odroid N2 with 4GB of RAM, sitting around, so here’s the log of getting it installed and running. ...
