Most don't have BOMs or assembly instructions unfortunately, as it would just eat up too much time.

Questions
How big is the Bed occupancy PCB?
It measures 74.9 × 58.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bed occupancy use?
16 parts, built around the ESP-01S and HX711. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Bed occupancy KiCad files?
From the thorio/esphome-projects repository on GitHub, at the commit this page was made from: the board is bed-occupancy/pcb/bed-occupancy.kicad_pcb and its schematic bed-occupancy/pcb/bed-occupancy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bed occupancy design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
