Bed occupancy sensor with ESP32-C6

Handles bed occupancy on two sides of the bed using two SF15-600 pressure sensors.

Uses ADC channels 2 and 3 to read the voltage and decide whether that side of the bed is occupied.

Zigbee2MQTT configuration

const exposes = require('zigbee-herdsman-converters/lib/exposes');
const e = exposes.presets;
const utils = require('zigbee-herdsman-converters/lib/utils');

const definition = {
    zigbeeModel: ['Bed Occupancy'],
    model: 'Bed Occupancy',

Which shows up as this:

Configure the project

Before project configuration and build, make sure to set the correct chip target using idf.py --preview set-target TARGET command.

Erase the NVRAM

Before flash it to the board, it is recommended to erase NVRAM if user doesn't want to keep the previous examples or other projects stored info using idf.py -p PORT erase-flash

Build and Flash

Build the project, flash it to the board, and start the monitor tool to view the serial output by running idf.py -p PORT flash monitor.

(To exit the serial monitor, type Ctrl-].)
