 {{ :supported_hardware:apcunits.png?direct&650|}} Once the interface is enabled and running you will be presented with a list of units created automatically by the interface. They will be given a default name that is based on the name you gave the interface and then the function.
-**AC Power**: shows online and is in an on state as long as the AC power is available. Since I’m polling the UPS relatively slowly it may not catch very short interruptions in power. If you need an immediate event about the loss and restoration of power let me know as that can probably be done through further software on the Pi. You may wish to change the default colors for this unit so that it displays green when the power is on and red when the power is off as it’s the off state that is the warning state.
+**AC Power**: shows online and is in an on state as long as the AC power is available. This is updated by the realtime user scripts we installed on the pi and also from polling. This way you can catch very short power failures that would not have been caught due to the normal intermittent polling. Note that in order to receive these real time events XTension and your UPS monitor Pi must be on the same subnet. You may wish to change the default colors for this unit so that it displays green when the power is on and red when the power is off as it’s the off state that is the warning state.
 **Error**: sometimes the software will append an error message to the status line. I have seen “LOWBATT” when my ups battery wasn’t going to be able to service the high load. This unit will display either “none” or the message sent. It will be off as long as there is no error and will turn on to alert you that the UPS has sent some error message. Use the On script to notify yourself of an error message from the UPS. Note that this is not the same as a failed battery self test, that message handled separately see the “Self Test Failure” unit below.

 **Self Test Failure**: If no self test has been run since the program connected then this unit will be in an off state and show “none”. Once a test has been run while it’s watching the unit label will change to “OK” unless there is a problem. If a self test failure of the battery or the load or whatever happens the label will change to the error message and the unit will turn on. Use the on script to notify yourself of a failed self test.
+**On Battery**: When the power has been out long enough for the UPS to be sure it isn’t a self test this unit will turn on. This is usually 5 or 6 seconds after a power failure. This will not turn on for power failure events shorter than that duration. This could be useful as you might turn off loads that are plugged into the UPS that are not necessary in a long term power failure condition to reduce the load and increase the runtime.
+**Charging**: Once power has returned and the UPS has switched off the On Battery unit this unit will turn on until the batteries are fully charged.
 If your device supports these additional readings then units to create them will be setup as well. Most simpler units do not support these.

 **Humidity**: The humidity of the room.
 ====History====
   * The apcupsd plugin first appeared in XTension 9.4.12 on Oct 2nd 2018 and is written by James Sentman
   * Version 2.0 of the plugin added support for realtime event reception of power fails and other messages. It also stops the ups software from shutting down the pi and killing the power from the UPS early. It was released in XTension version 9.4.13 in November of 2018.
