# APC UPS devices
Receiving and using information like online status (on AC power or running on battery), battery charging level, autonomy time and more from APC UPS devices.
All you need is a APC UPS device which is connected to a [apcupsd]( daemon. The daemon can run locally on the openHAB machine and or somewhere else. If it runs remote you need to install apcupsd as we access the remote apcupsd installation using the apcaccess command.

First you need to put the *USV_dump_log* bash script somewhere where you can access it. I created a directory */home/openhabian/scripts* for scripts like this one.

Then create a thing in Paper UI. Use the Exec binding and enter the following parameters:
* **Name:** USV_dump_log
* **Command:** /home/openhabian/scripts/USV_dump_log 3551
* **Transform:** REGEX((.*))
* **Interval:** 60

The port (*3551* is the apcupsd standard port) for accessing the UPS device through apcupsd is a parameter as I check three UPS devices and only want to use one script. This is also the reason why I configured the remote UPS devices (all my UPS devices just have a USB cable, no network interfaces) in the local apcupsd. The data is received from the remote apcupsd installations. You can also modify the IP in the script to access a remote apcupsd installation.

The new thing *USV_dump_log* gets an id like _exec:command:**a1b2c3d4**_ which you then need to enter in the item created through the *ups.items* file.

* **USV_dump_log**: Put the bash script into */home/openhabian/scripts* (or somewhere else you like) and *chmod 755* it to make it executable.

* **ups.items**: Put this file into your */etc/openhab2/items* directory and modify it for your specific setup. Maybe everything suits your needs, but you need to modify the string item *USV_Log* and match the command id in the channel command to the thing you created earlier in Paper UI.
* ****: Put this file into your */etc/openhab2/transform* directory.
* **ups.rules**: Put this file into your */etc/openhab2/rules* directory. You may want to modify it for your specific setup. You find two excamples for actions if AC power fails. In this case a XMPP message and a message through Telegram is sent.
