This driver, formerly called newhidupsreplaces the legacy hidups driver, which only supported Linux systems.

It should detect any UPS that uses the HID power device class, but the amount of data will vary depending on the manufacturer and model. You may use the "explore" driver option to gather information from HID UPSes which are not yet supported; see below for details.

The default value is 20 in seconds. This ensures the machines connected to the UPS are, in all cases, rebooted after a power failure. The default value is 30 in seconds. Between two polling requests, the driver will wait for interrupts aka UPS notificationswhich are data changes returned by the UPS by itself.

This mechanism allow to avoid or reduce staleness message, due to the UPS being temporarily overloaded with too much polling requests. Try -DD for finding out the strings to match. The argument is a regular expression that must match the bus name where the UPS is connected e. This must always be combined with the "vendorid" option. In this mode, the driver will not do anything useful except for printing debugging information typically used with -DD.

Note that it will also install other USB drivers. You also need to install manually the legacy hotplug files libhidups and libhid. On Linux with MGE equipment, you will need at least a 2. Unlike previous versions of this driver, it is now possible to control multiple UPS units simultaneously with this driver, provided they can be distinguished by setting some combination of the "vendor", "product", "serial", "vendorid", and "productid" options.

This should solve the issue. Unattended shutdowns The hardware which was used for development of this driver is almost certainly different from what you have, and not all manufacturers follow the USB HID Power Device Class specifications to the letter. If you rely on the UPS to shutdown your systems in case of mains failure and to restart them when the power returns, you must test this. You can do so by running upsmon -c fsd. With the mains present, this should bring your systems down and then cycle the power to restart them again.

If you do the same without mains present, it should do the same, but in this case, the outputs shall remain off until mains power is applied again.Unfortunately the configuration process is tweaky and the included documentation is minimal and cryptic.

Adapted from Engadget. Select the package for installation and click on Apply. Now log in as the superuser, then create and edit five configuration files:. The configuration is pretty simple. Current user id: nut Serial port owner: root 0 Serial port group: dialout 20 Mode of port: D ups.

Find your UPS model on the NUT hardware compatibility list and substitute the corresponding driver for usbhid-ups above. They probably use the same driver. Next, issue the following two commands to force udev to make the necessary permissions change:. Finally, we can make sure that nut properly detects the UPS:.

Now, we need to configure upsd and upsmon. Why the extra level of indirection? Multiple instances of upsmon can be started on different machines. They can all share the same physical UPS.

This rejects all connections not originating from the local machine. If you need to monitor from multiple machines, see the man page for upsd. You should add multiple users if you are monitoring from multiple machines. See the man page for upsd.

By default, upsmon waits until the battery is at a critically low level before initiating a shutdown. As you can see, this second method is quite a bit more difficult to configure. That said, using upsd and upsmon, as opposed to nut-hal-drivers, is probably the more reliable method of monitoring a UPS.
