A friend of mine reached out and asked me about automating some aspects of their aroma therapy treatment.
The device they’re using for aromatherapy is the Arizer XQ2 and we agreed that integration with their existing Home Assistant setup would be ideal.
Part of the reason for developing my SB8200 monitor was to get to the bottom of some infrequent but regular outages.
To make a long story short, the LAG implementation on the modem seems to have some issues. A quick google will return many complaint threads detailing issues with the modem regularly locking up all traffic stopping. More annoyingly, these reports date back years and allege that later revisions of the firmware might fix the issue for good.
This is a very short “announcement” post.
To beef up my home-lab observability stack, I’ve been working on a few projects to expose more data to Prometheus. Getting metrics from my cable modem has been on the “todo” list for literally years. There have been various metric exporters written in the past but they have either been archived/deleted off of GitHub or are otherwise inappropriate for my needs. So, I wrote my own.
This isn’t going to be a long post. I’m working on a larger project but hit a snag and I didn’t find any easy/obvious solutions online so I thought I’d share what I came up with.
Details will come later when the bigger project is ready to be released so you’ll have to forgive me for the lack of context. Essentially I have a large / multi-hour print that almost fits on my MK3s print bed but is too large to slice as is.
It is surprisingly hard to find a device that can dump details about the various protocols and negotiated standards for a HDMI connection. For how ubiquitous HDMI is, you’d think that there would be a lot of devices that can do this. There are LOADS of devices that can snoop USB and Ethernet, but HDMI is a bit of a different beast, apparently.
After a bit of searching, I found the Altinex TE460-137 could do exactly what I wanted.
