@lil5
First a quick rant: DO NOT BUY SWITCHBOT. They are unsafe and have no warranty and they can suck whatever piece of my anatomy they find most distasteful. We couldn't afford to replace them, but we had to anyway because Fire is Bad.

Ahem. Anyway. Yes! The grow is driven by #HomeAssistant (along with the rest of the #snarkhouse.) I can post the grow hardware BoM (my lights, plugs, etc) if you're interested, but the basic stack is #HomeAssistant as a #Truenas VM with everything else on ARM64 under #k3s. The control plane is CM4 on #TuringPi2, and Zigbee/Zwave pods talk to ser2sock + node-feature-detector to find their USB radios. (They are plugged into the client port of the Turing, so I can move them programmatically.)

On the far side of the radios, a cheap #esp32 Rover handles #bigear listening as well as the MiFloras and #BLE hygrometers. Inside the grow tent, an #esp32cam on a 3d printed mount watches over the grow. Power relays are a mix of old #Securifi peanuts and new #ThirdReality switches. (DO NOT BUY SWITCHBOT.)

The grow room environment graph. It shows about 24h. On the bottom, a large yellow overlay shows the lighting cycle. Very regular red strips show the stir fan raising the humidity, with fewer dark blue bands indicating the exhaust fan dehumidifying frequently at night and less so when the LED and associated cooling fan are running. The temperature climbs suddenly from 65F to 75F when the lights come on. I should align the left and right axis labels but I won't.

Here is today's reminder that #Discord is NOT a forum!

@turingpi I'm looking at you. (Nice to see you here though!)

Discord is directly hostile to #opensource users.

It is not #accessible
It is not archived.
It does not allow anonymous viewing.
It is not searchable, and neither is it indexed by external search engines.
Data is walled in and unexportable.

Bonus round: Chat is also NOT a forum!

Chat is a chronological firehose, good for temporally transient information, largely ungrouped. Forums are a topical tree, good for longer-lasting information grouped by subject.

If you would write it down in real life (including email) then use a forum.

If you would only say it out loud (in the hallway or on a call) then chat is perfectly fine.

And if you say it out loud while someone else writes it down, tell your assistant to use a forum.

And here we go: blog.mei-home.net/posts/turing

A blog post about the Turing Pi 2 cluster board, which can be used to hold up to four Raspberry Pi CM4 and some Nvidia Jetson modules.
I'm also describing how I arrived at wanting to run 8 small SBCs in my Homelab.

First node is up and successfully netbooted. Currently still annoying: The BMC gets a different MAC every time you power it on or off.

Only the BMC's web interface is accessible by default, but it allows e.g. switching on/off power for each individual node.

Next step, connecting to the serial console of the BMC and looking around. It's OpenBMC, so basically Linux.

A powered on Turing Pi 2 board. It is connected to a BeQuiet! power supply. The first slot is populated with a CM4 module. There are a number of LEDs shining in comforting green.
