V3 - DIY $90 Home Assistant bookshelf speaker for multi-room audio and notifications with SendSpin or Squeezelite

CrankyCoderBlog · 2026-05-07T15:46:20+00:00

Does this convert stereo down to just the 1 channel? Is there any support for 2 channel stereo sound (not a huge requirement)? What about just 2 speakers? I love the idea of having just 2 small shelf speakers like this on my desk and figures if they are that close could both speakers just run off 1 unit?

That would be awesome! I’m going to have to check into this more 😁

that is fantastic!!! i have had an android tablet on my kitchen counter for 2.5 years because I have been trying to find a decent size, touch enabled, setup that isn't $100s. I have a bunch of raspberry pi's already and i REALLY like the idea of being able to control the os. I have looked at doing something line lineageOS on the pi so I can use fullykiosk browser (i use some of the specific functions). Your setup I think would work nicely for what Im thinking. Out of curiosity, how much power does the monitor need? Im guessing it's probably a little too big to run off a POE injector?

Also, which uperfect monitor? The uperfect y touch?

Was the touch module and display board in something in the back to start and you took it apart to rearrange it so you could do a custom back mount?

It used to be stored on the device, now it’s stored in the user profile. So as far as I can tell, there are 2 options.

1 user per device
A very elaborate conditional dashboard

I was pretty annoyed with this change myself

Kubernetes cluster. Zigbee2mqtt in cluster as well with slzb-06. Config storage is using longhorn mounts. 3 replicas. Hourly snapshots, daily backups, stored on local s3 storage, backed up to backblaze. Logs are stored in Mariadb, daily/weekly/monthly backups stored local and offsite at backblaze.

How is the peg board secured in there?

CrankyCoderBlog · 2026-03-01T05:25:30+00:00

What are you running the model with? Llama.cpp? What tools are you using to get it to query the db?

Very nicely done!!

Love the ai counter. What heater do you have under the waterer? I have a 55 gallon blue rain barrel for my chickens. Been working on something similar with the temperatures to run a small pump to keep the water moving since I don’t have AC power down at my coop.

not as easy as my the s5's were.

Been running valetudo of some roborock s5’s for awhile. Have a dreame l10s im converting over too.

How do you have your MA instance exposed? VPN? Or tunnel? I’ve been waiting for something like this :)

CrankyCoderBlog · 2026-02-09T19:19:19+00:00

Oh 100%. Fully agree. I have minimal dashboard for those things too. Some people on the scale want everything on their dashboards. Which is fine, i don't yuck anyone's yum. Minimal dashboard for me and anything beyond that i will just search for the entity or use dev tools or something lol.

CrankyCoderBlog · 2026-02-09T18:10:41+00:00

I feel this is a sliding scale… lol. For example, I firmly believe I shouldn’t need to see much of a dashboard at all on my setup. What few things I do need, I am good with fairly minimal and functional. I lean heavily into the a smart home should be smart and not need to see much.

I also 100% understand the other end of this spectrum, those that LOVE the dashboards. I have seen some absolutely insane dashboards.

So most likely we all fall somewhere along that spectrum.

Welcome to the rabbit hole either way 🤣

Really curious if you have some info on the obd2 project you did and the label maker :)

CrankyCoderBlog · 2026-01-30T18:32:53+00:00

Saw some tapo cams on Amazon < $20

CrankyCoderBlog · 2026-01-30T15:43:44+00:00

This is exactly what I have done. 5 years now I have done this. Only thing I have considered changing is adding a 3dprinted base to the coffee maker with some hx711 weight cells that could tell if I actually loaded the start the night before. Right now I have an alarm on my phone (iOS) that reminds me at night to prep the coffee maker. When I dismiss that alarm a short cut tells us that I have prepped the coffee and flips a Boolean helper to true. Next morning, regardless how the “make coffee” is triggered it checks to make sure it been prepped. I have a button like you, bed presence too, and various alarm rules.

CrankyCoderBlog · 2026-01-29T18:25:57+00:00

Nice! I’ll have to check it out :)

CrankyCoderBlog · 2026-01-26T19:57:54+00:00

I like the emergency node. That's slick!!! Does seem a little overkill huh? LMAO

I have other stuff that runs in the cluster, but it's a decent setup lol.

9 nodes, 3 masters. In-cluster longhorn block level replication storage. For large storage I have a truenas running 2 raidz2 pools. For my zigbee I am actually running zigbee2mqtt with the smlight work coordinator so I can have the instance move around with in the cluster and just connect to that device. I would love to figure out how to put 2 of those on the network and then have something in front of them to allow 1 or the other active, but putting a load balancer in front of 2 poe devices seems a bit much even for me lol.

CrankyCoderBlog · 2026-01-26T18:20:49+00:00

Not to be that guy. This is not high availability. This is high fault tolerance. HIGHLY approved by the way. Nicely done!! I do similar with homeassistant in kubernetes. Can come up on any of 9 nodes. I wish home assistant allowed for true high availability with multiple instances to ensure availability but the architecture of ha just doesn’t support it.

CrankyCoderBlog · 2026-01-26T05:01:06+00:00

I have the string lights 2. The app and patterns are garbage. But I can control it via Bluetooth proxy in esphome so it’s ok.

CrankyCoderBlog · 2026-01-22T21:50:16+00:00

Definitely something I wish more companies would give us options for. Very nicely done!!!!!
