The server code for the Isadore Dryer Management System. Originally released with an open source license in 2019 by Dan Elliott and Russell Valentine. It is designed to monitor environmental conditions in corn seed dryers.


  1. Setup a postgresql database. Setup schema using the files in ./server/sql
  2. git clone
  3. Until it is templated search for in the code and switch it to what you want. grep -r *
  4. cd clients/www
  5. ant deploy -Dsite=sitename
  6. cd ../../server
  7. ant deploy -Dsite=sitename
  8. cp settings.cfg.example /www/sitename/webapps/isadore/settings.cfg
  9. Edit settings.cfg with your auth info
  10. Setup WSGI server to use app.wsgi

Example to install on Ubuntu LTS

Note In these examples $DBNAME should be the name you choose. Maybe your dryer name, do not keep it as $DBNAME.

Update and Install prereqs

apt update && \
apt upgrade && \
apt install -y postgresql postgresql-contrib postgresql-plpython-10 apache2 libapache2-mod-wsgi python-matplotlib nginx python-pip postgresql-server-dev-10 ntpdate ntp sendmail git npm ant && \
pip2 install bottle==0.12.17 beaker==1.5.4 pytz http-parser==0.6.2 restkit==4.2.1 iso8601==0.1.10 psycopg2 twilio==6.29.4 croniter==0.3.12 && \
pip2 install git+
npm install -g coffeescript

Setup database

Check out code

git clone && \
cd isadore_server && \
export GIT_LOC=`pwd`
su - postgres
createuser $DBNAME
createdb $DBNAME -O $DBNAME
psql -c "ALTER USER $DBNAME password 'somerandompassword';

Now we need to create the tables and everything

cd $GIT_LOC/server/sql
psql -U $DBNAME -f 0_json_methods_extra.sql
psql -U postgres -d $DBNAME -f 2_run_as_postgres_2.sql
psql -U $DBNAME -f 3_funcs.sql
psql -U $DBNAME -f 5_schema_index.sql
psql -U $DBNAME -f 6_schema_seed.sql
psql -U $DBNAME -f seed_customers/seed_generic.sql
psql -U $DBNAME -f seed_customers/init_readings.sql

Deploy Server code

mkdir /www/$DBNAME
cd $GIT_LOC/server
ant deploy -Dsite=$DBNAME
cd ../clients/www
ant deploy -Dsite=$DBNAME
mkdir -p /www/$DBNAME/webapps/ROOT
mkdir -p /www/$DBNAME/logs
touch /www/$DBNAME/logs/time.log
touch /www/$DBNAME/logs/bottle.log
chown www-data /www/$DBNAME/logs/time.log
chown www-data /www/$DBNAME/logs/bottle.log
chown -R russ:www-data /www/$DBNAME/webapps/isadore
cp $GIT_LOC/server/settings.cfg.example /www/$DBNAME/webapps/isadore/settings.cfg

Make a file /www/$DBNAME/webapps/ROOT/index.html and have below be the contents:

<meta HTTP-EQUIV="REFRESH" content="0; url=./isadore/s/login.html">

Passwords Configuration

Set DB midpass:

psql -U $DBNAME -c "update table general_config set mid_pass='someotherpassword';"

Modify /www/$DBNAME/webapps/isadore/settings.cfg Make sure midpass, dbuser, dbpass, dbhost are correct.

If using twilio for alerts, make sure account and token are correct for your twilio account.

Setup Apache as WSGI server

sh /usr/share/doc/apache2/examples/setup-instance $DBNAME
ln -s /etc/init.d/apache2 /etc/init.d/apache2-$DBNAME
systemctrl enable apache2-$DBNAME
mkdir /var/run/apache2-$DBNAME

Edit the file /etc/apache2-$DBNAME/sites-enables/000-default.conf It should contain:

<VirtualHost *:80>                                                                                          
        ServerAdmin webmaster@localhost
        DocumentRoot /www/$DBNAME/webapps/ROOT                                                
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
        <Directory /www/$DBNAME/webapps/ROOT>
                Require all granted
        WSGIDaemonProcess $DBNAME processes=2 threads=15 display-name=%{GROUP}
        WSGIProcessGroup $DBNAME    
        WSGIScriptAlias /isadore /www/$DBNAME/webapps/isadore/app.wsgi
        <Directory /www/$DBNAME/webapps/isadore>
                Require all granted

Startup apache:

/etc/init.d/apache2-$DBNAME start

You should then be able to log in with the default username and password, be sure to change it:

Settings -> General Config

After logging in pasting the contents of $GIT_LOC/server/src/general_config.example.json into the Settings -> General Config, it may help get your Current Data views started. For further customization look into at the top comments in the file $GIT_LOC/clients/www/src/coffee/handler/

Alarm Service

There is a alarm service to watch if it should sent email or text alerts. A way to start this one boot is using systemd.

Make a file in /etc/systemd/system/$DBNAME_alarmwatcher.service

with contents

Description=AlarmWatcher Service

ExecStart=/usr/bin/python2 start
ExecStop=/usr/bin/python2 stop 


Then Run:

systemctl enable $DBNAME_alarmwatcher
systemctl start $DBNAME_alarmwatcher
You can’t perform that action at this time.
