Sure, follow this guide until you get to the php portion and then stop.
Make sure you have git installed.
sudo apt-get install git
Then open a bash window and run these commands
cd ~/
git clone https://github.com/jp0550/webCoRE
cd webCoRE
git checkout hubitat-patches
cd dashboard
sudo ln -s `pwd` /var/www/webcore
Now edit the following file to the following
/etc/apache2/sites-available/000-default.conf
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
ServerAdmin webmaster@localhost
DocumentRoot /var/www/webcore/
<Directory "/var/www/webcore">
AllowOverride All
</Directory>
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>
Run the following commands
sudo a2enmod rewrite
sudo service apache2 restart
Use the url for your raspberry pi and it should now show you webcore
Go to the webcore settings on your hubitat and enable Custom urls.
In the first box put the http address of your hubitat
In the second box put the http address of your pi
Hit done and you should be see your local instance of webcore come up when you hit Dashboard on the settings page in hubitat.
I wrote most of this from memory so let me know if you get stuck on something.
