Please run the following command

     /path/to/usbhid-ups -DDD -a upsname > Smart-UPS1500RM.log 2>&1

Make sure to kill any usbhid-ups drivers lingering in the background  
before running this command. Wait 15 seconds and then kill it with  
Ctrl-C. Gzip the log file that is created and post it here.

We already have this mapping. Could it be that you actually meant  
"UPS.Output.DelayBeforeStartup"? Posting the logs is sufficient, it  
will provide us with all the information we need.

We only support it if we can find the corresponding HID mapping.

This is how it is supposed to work. The ondelay timer is only used in  
case the power is present, otherwise the unit will switch on as soon  
as the power returns. See also 'man 8 usbhid-ups' and the USB HID PDC  
specifications. The only thing the driver can do is to set the timers.  
It is up to the UPS how it deals with them (we can't control the UPS  
when the power is out).
