A simple case for using an LD2410C radar sensors with an ESP32 C3 Mini that can be mounted to the HSW. I've included a little spacer that can be slid over the pins of the LD2410C to help with soldering to the ESP board.
BOM (affiliate links):
Prints require no supports. I've used PLA without issue.
I'm using this YAML config on these with Home Assistant and they're currently my favorite presence sensor.
Will require a blank insert to attach to the HSW.
