In config.pl, the -r1 option is added to the command line when the driver is called:

  if ( $hive_weight_sensor eq "cpw200plus" ) {
           $raw_hive_weight=`/usr/bin/sudo /home/hivetool/cpw200plus.sh -r1 -d $hive_weight_device`;
       }
  elsif ( $hive_weight_sensor eq "HX711") {
      $raw_hive_weight=`/usr/bin/sudo /home/hivetool/hx711.sh -r1 2>&1`;
       }
   elsif ( $hive_weight_sensor eq "HX711py") {
      $raw_hive_weight=`/usr/bin/sudo /home/hivetool/hx711py.sh -r1 2>&1`;
       }

Boot

Stretch boots directly into the window system.

                     ....

Update, upgrade

update your system's package list and then upgrade all your installed packages to their latest versions:

sudo apt-get update
sudo apt-get dist-upgrade

Install RPi-Cam-Web-Interface

https://elinux.org/RPi-Cam-Web-Interface

First install motion:

sudo apt-get install motion

Then install RPi-Cam-Web-Interface

git clone https://github.com/silvanmelchior/RPi_Cam_Web_Interface.git
cd RPi_Cam_Web_Interface
./install.sh

Remove packages we don't need

sudo apt-get remove --purge scratch dillo squeak-vm squeak-plugins-scratch sonic-pi
sudo apt-get autoremove
sudo apt-get clean
rm -rf /home/pi/python_games
sudo rm -rf /opt/minecraft-pi
sudo apt-get remove --purge scratch dillo squeak-vm squeak-plugins-scratch sonic-pi

Install packages we need

sudo apt-get -y install gawk bc apache2 libusb-dev libgd-graph-perl libexpat1-dev sqlite3
sudo apt-get install dh-autoreconf libudev-dev
sudo apt-get install gnuplot

Install perl modules

sudo cpan CGI Date::Format XML::Simple DBI DBD::SQLite Chart::Gnuplot
sudo cpan DateTime

Web Server

Configure apache

Link the cgi.load and include.load module to mods-enabled
ln -s /etc/apache2/mods-available/cgi.load /etc/apache2/mods-enabled

ln -s /etc/apache2/mods-available/include.load /etc/apache2/mods-enabled
Add .pl to AddHandler cgi-script
sudo vi /etc/apache2/mods-enabled/mime.conf

uncomment #AddHandler cgi-script .cgi (around line 219) and add ".pl .py" so it looks like:

AddHandler cgi-script .cgi .pl .py
add Includes and +ExecCGI to Options:
sudo vi /etc/apache2/apache2.conf

In stanza <Directory /var/www/>

change

Options Indexes FollowSymLinks

to

Options Indexes FollowSymLinks Includes ExecCGI
Add index.shtml to DirectoryIndex:
sudo vi /etc/apache2/mods-enabled/dir.conf

Change

DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm

to

DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm index.shtml
Set up apache to listen on port 8080 if using port forwarding:
sudo vi /etc/apache2/ports.conf

add Listen 8080
Restart Apache

sudo apachectl restart   or      sudo/etc/rc4.d/S02apache2 restart

Set sudo user privileges for Apache

This is necessary to allow config.pl to read the sensors. Run visudo to edit the sudo config file:

sudo visudo

and insert these line in the "User privilege specification" section:

# User privilege specification

Install Sensor Drivers

BME680

PiMoroni Python driver

sudo curl https://get.pimoroni.com/bme680 | bash

DHTxx Temperature/Humidity Sensor

This code uses the PiGPIO libraries (pigpiod).

Download the DHT11/21/22/33/44 Sensor code from http://abyz.me.uk/rpi/pigpio/code/DHTXXD.zip
Unzip
compile

Note that this code uses the Broadcom GPIO numbering so Ras Pi GPIO 2 <=> Broadcom GPIO 27 Ras Pi GPIO 3 <=> Broadcom GPIO 22

mkdir /home/downloads/DHTxx
cd /home/downloads/DHTxx
wget http://abyz.me.uk/rpi/pigpio/code/DHTXXD.zip
unzip DHTXXD
gcc -Wall -pthread -o DHTXXD test_DHTXXD.c DHTXXD.c -lpigpiod_if2

HX711 weight ADC

c code driver is hx711wp

Note: The original hx711 code has been modified to use the wiringPi library and a bug fixed.

Download the software from gitHub
cd /home/downloads

sudo git clone https://github.com/ggurov/hx711
replace hx711.c with hx711wp.c and add locking.h
compile
gcc -o hx711wp hx711wp.c -lwiringPi
Copy hx711 command to /usr/local/bin:
sudo cp hx711wp /usr/local/bin/hx711
To read the battery voltage, copy hx711wp_chanB command to /usr/local/bin:
sudo cp hx711wp_chanB /usr/local/bin/hx711wp_chanB

Install National Time Protocol Daemon (ntpd)

sudo apt-get -y install ntp

Install RTC support

Edit /boot/config.txt. Add:

#enable RTC DS3231 module
dtoverlay=i2c-rtc,ds3231

Edit /lib/udev/hwclock-set and comment out these three lines:

#if [ -e /run/systemd/system ] ; then
# exit 0
#fi
