 The UPS plugin provides a connection between XTension and a UPS that is compatible with the built in OSX support for such devices. If you see a battery level in the system for a UPS connected via USB then the same UPS will be compatible with the UPS plugin for XTension. Build 830 of XTension adds the reporting of disk drive space to this plugin too.
-The UPS plugin is included in demo mode in the release version of XTension, only a plugin serial number purchased from [[http://sentman.com/UPS_Monitor.html|sentman.com]] is necessary to unlock it for full time functionality. The demo mode will run for only 1 hour before turning itself off during any given session with XTension. So you can verify that it works with your UPS device before purchasing.
+**NOTE** there is a problem with most MacOS X versions where the “restart after a power failure” setting in the energy saver does not work if there is a UPS connected to the computer via USB. This is not OK for a home server so you should consider not connecting your UPS to the Mac via USB but rather using a raspberry pi and the new [[supported_hardware:apc|acpupsd]] plugin if you have an APC ups.
 By providing a pseudo unit associated with AC Power availability you can take action in response to a power failure or power restoration, even a short duration one which may require that problem appliance modules be reset as they can turn on if the power flickers. The time to empty value can be used to give warnings of immanent shutdown.
