Anyone try this Wifi motion sensor?

Wi-Fi CSI motion sensing for ESP32. C++ SDK, ESPHome, Native, and Matter frontends, browser tools, and a CLI for the full device lifecycle. GPLv3 and commercial licensing. - francescopace/espectre

Just read about this and was wondering if anyone has tried it. Pros/cons/notes? This seems pretty neat on the surface and I plan on trying it myself.

Yes, yes And YES!!

This is really great. Grab some boards with an external antenna, I guess the S3 variants are the best.

This guy is really active and thorough.

Home Assistant integration is a wip, right now the cyd is a topic.

Star, follow and try it!

Awesome. Good to hear good things about it. I have some spare ESPs laying around to try this on so I guess I know what I'm doing this weekend.

All I get after following the documentation, is a compiler error:

CMake Error at /data/external_components/fd3660ad/src/cpp/espectre_git_version.cmake:62 (message):

ERROR Component discovery failed

Edit: Managed to work around it. Now it actually detects movement! Just be aware this project looks like it's cooked up with a lot of AI assistance. There's a million pages of documentation, mostly convoluted and repetitive while telling slightly different things to do... And a compiler error is never a good first impression... It seems to work, though!

Now I have to find a few spare ESPs, which aren't already doing BLE or something, and see what kind of strain it puts on my wifi network.
