Might be a bit of an overkill if you just want to check the certificates, but I'm using Icinga (formerly known as Nagios) to keep track of all of the systems - including webpage certificates. - Source: Reddit / 12 months ago
Some of it can be migrated rather easily to Icinga https://icinga.com/. Icinga forked from Nagios many years ago, they rewrote the engine and have done a nice WebUI.

NagVis is a plugin for both Nagios and Icinga. They advertise geographic maps, but you can put building floorplans in it too. We used it with Nagios for years and it worked great.
