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. ...
Why k3s and not stick with k8s? I wanted to experiment with k3s. They package everything you need in a single binary, don’t package in deprecated parts of k8s, and it works on Intel, ARMv7 and ARM64. It seemed like it’d be a less painful way to runn Kubernetes on my ARM cluster. ...
One of the reasons I set up my cluster was that I’m running out of space on my NAS. I don’t want to buy a whole new chassis, and while I could have put individual file shares on each cluster node, that would be both inconvenient and not provide any data redundancy without a lot of brittle home-rolled hacks to rsync data from node to node. And since distributed file systems are a thing, I’d rather not resort to hacks. ...
I realized I forgot to include a parts list for the cluster in my ARM cluster post (all prices are as of March 3rd, 2019), so here we go. ...
I recently decided to set up a Kubernetes cluster in my basement, partly because I’d never set a cluster up from scratch by myself, and partly because my existing NAS was beginning to run out of headroom. ...
