Web-Accessible History From OpenHAB MySQL Persistence Database

My husband has wanted a quick/easy way to see the data stored in OpenHAB’s MySQL persistence database, so I put together a very quick (and ugly) PHP page that provides a list of all Items. If you click on an item, you can page through the item’s records. The index.php from the page is available here. You need a web server (I am using Apache on Fedora), PHP (I am using 5.6) and MySQLi (php-mysqlnd package).

This is a bit of paranoia on my part, but even on a page that is ONLY available internally … I don’t like to use an account with read/write access to display data. I create a new user and assign read access:

CREATE USER 'YourUserName'@'localhost' IDENTIFIED BY 'P#ssw0rdH3r3';
GRANT SELECT ON openhabdb.* to 'YourUserName'@'localhost';
FLUSH PRIVILEGES;

Then use *that* user in the php code. This example has a web server running on the database server – and you connect to the MySQL server via localhost. If your web server is located on a different host, you’ll need to create and grant ‘YourUserName’@ the web server hostname.
