I Modified the project to be able to store a LD2410C instead of the temp sensor.

Also i opened part of the top case for the light sensor, as the measurements were pretty low.

There is plenity of space for the cables, so you should be able to even make it shorter.

My cables are a bit too long but it works perfectly

The case it's for the ESP32 D1 Mini but if you remove the center square on the top, you can fit a Wemos ESP8266 in there.

This is the code on ESPHOME for the Wemos ESP8266 D1 Mini:
