I've tried running this on a Seeed Studio XIAO ESP32S3 (dual-core, 8mb flash, 8mb psram). I've assigned gpio ports and started to project with no issue, but the predictions seem to be very very slow. Between the "channel enabled" message and the predictions message were about 10 minutes.
I really like the simplicity of the project and would love to hear back!
