-{{:​supported_hardware:​apcexample.png?​direct&​300 |}}Monitoring an APC UPS via the [[http://​www.apcupsd.org|apcupsd]] daemon. This plugin will connect to the apcupsd daemon and collect the battery state, AC power state, load percentage, time left and other important data even if the UPS in question isn’t physically connected to your Mac. If you wish to talk to a physically connected UPS please have a look at the original [[UPS]] plugin. You probably don’t actually want to have a UPS physically plugged into your Mac server anyway believe it or not, see below, but it can be very useful to be able to monitor the UPS anyway. You may have other computers, DVRs, WiFi access points, or other home automation nodes that are on separate UPS’s and it can be very helpful to be able to monitor those and know their approximate runtime and battery health as well. Installing this plugin and apcupsd on a raspberry pi can give you all that.+{{:​supported_hardware:​apcexample.png?​direct&​300 |}}Monitoring an APC UPS via the [[http://​www.apcupsd.org|apcupsd]] daemon.

 There is a rather severe problem with connecting a UPS directly to a Mac OS Server. (not MacOSX Server, but any Mac acting as a server) You might wonder why you wouldn’t want to just connect the UPS to the computer? It will shut it down properly then and all will be well. Except that if you have the energy saver preferences set up to properly shut down your computer then it will not restart when the power comes back. There is a setting for most Macs to “restart after a power failure” but this only works if you let the power actually be pulled and NOT do a proper shutdown. The bug in MacOS is that this doesn’t work if you have a UPS connected to the machine! This has been broken for several major OS versions now. If you are running a Mac server and wish to use a UPS then you don’t actually want the UPS connected to the Mac or it will not restart without you there to push the button. There is a rather severe problem with connecting a UPS directly to a Mac OS Server.
