Zoneminder Snapshot With openHAB Binding

When we upgraded to Fedora 28 on our server, ZoneMinder ceased working because some CakePHP function names could no longer be used. To resolve the issue, I ended up running a snapshot build of ZoneMinder that included a newer build of CakePHP. Version 1.31.45 instead of 1.30.4-7 on the repository.

All of our cameras showed up, and although the ZoneMinder folks seem to have a bug in their SQL query when building out the table of event counts on the main page (that is, all of my monitors have blank instead of event counts and my apache log is filled with

… it works.

Until Scott checked openHAB, where all of the items are offline. Apparently the openHAB ZoneMinder binding is using the cgi-bin stuff to get the value of ZM_PATH_ZMS. A config option which was removed from the database as part of the upgrade process.

The calls from openHAB yield 404 errors in the access_log

Unfortunately they’ve changed the URL to get these values — it’s “munged” from the config file as the parameters are no longer stored to the Config table.
http://zoneminder.domain.ccTLD/zm/api/configs/view/ZM_PATH_ZMS.json
is now
http://zoneminder.domain.ccTLD/zm/api/configs/viewByName/ZM_PATH_ZMS.json

So … that’s a problem!
