I'm trying to use NUT with PowerCom RPT-1000AP on CentOS 6/7 ups.conf: [RPT-1000] ??? driver = "usbhid-ups" ??? port = "auto" ??? vendorid = "0D9F" ??? productid = "0004" ??? product = "HID UPS Battery" ??? serial = "004-0D9F-000" ??? vendor = "POWERCOM Co.,LTD" ??? bus = "002" ??? pollfreq = 10 ??? offdelay = 120 ??? ondelay = 180 Monitoring works fine, but: upscmd -u UPSUSER -p UPSPASSWD -a RPT-1000AP shutdown.return says "OK" and does nothing. Meanwhile apcusd is able to poweroff this UPS correctly. USB dump by apctest "Test kill UPS power" command: CTRL_IN(0.0): 00:00:0000:0000:1030303030 # 2.5421979427337646 CTRL_OUT(0.0):21:09:0310:0000:1040000000 # 0.0000979900360107 CTRL_IN(0.0): 00:00:0000:0000:1030303030 # 0.0175840854644775 CTRL_IN(0.0): 00:00:0000:0000:0f00 # 0.0109839439392090 CTRL_OUT(0.0):21:09:030f:0000:0f3c00 # 0.0000259876251221 CTRL_IN(0.0): 00:00:0000:0000:0f08 # 0.0591070652008057 INTR_IN(0.1): 0a0c20 # 3.8889238834381104 INTR_IN(0.1): 0e64 # 0.1909830570220947 INTR_IN(0.1): 1401 # 0.1928460597991943 <--a lot of same messages--> INTR_IN(0.1): 0a0d00 # 8.3736109733581543 INTR_IN(0.1): 0e52 # 0.1944248676300049 INTR_IN(0.1): 1401 # 0.1950931549072266 INTR_IN(0.1): 379002 # 0.1951398849487305 <-- UPS powered OFF here--> With the best regards! -------------- next part -------------- An HTML attachment was scrubbed...
