I built my own motion activated stairwell lights using an ESP32 and Home Assistant. Works pretty well.

So then I decided to set up some LED strip lights for my office with really nice wireless buttons from IKEA.

I confirmed that the buttons and the lights both were zigbee compatible, but I missed that one supported only Thread and the other only Matter. So now I have two identical antennas, each handling a different protocol.

Cool stuff. I first worked on ML for exploratory synthesis in 2012, and am still in related areas.

Once you have the experimental loop running, I suspect it will be quite difficult to hill climb on this task.

There will be some improvements you can make to the harness, but I suspect you'll be doing a lot of human in the loop review and providing feedback that goes back into the harness instructions.

I know it's fashionable to imagine automating the whole process, but everything I've seen is that the only systems that succeed are the ones that are augmenting an expert.

This idea seems to be coming up in multiple places.

Here's one from Deepmind:

Many years ago (13?), I was around when Amazon moved SABLE from RAM to SSDs. A whole rack came from a single batch, and something like 128 disks went out at once.

I was an intern but everyone seemed very stressed.
