highspeed Posted September 20, 2016 Share Posted September 20, 2016 APC is starting to support the open modbus protocol over USB in their Smart-UPS line. In the newest devices, modbus provides much more data than the proprietary protocol that the USB interface uses by default in apcupsd. I think as more users start purchasing these modbus-enabled APC devices, this feature will be a very helpful addition to unRAID. In order to support this new protocol, apcupsd needs to be built with the './configure --modbus-usb' flag. The binary in unRAID as of version 6.1.9 does not appear to have been built with this flag. I'd like to request that this be included in future versions of unRAID. Thanks! Quote Link to comment
TUMS Posted November 29, 2016 Share Posted November 29, 2016 BUMP..... YES! Would very much like to see it added so USB modbus functions properly. Quote Link to comment
highspeed Posted January 6, 2017 Author Share Posted January 6, 2017 (edited) For those interested, I created a slackbuild for unRAID that includes the --modbus-usb flag. You can put it in /boot/extra and it will overwrite the LT-supplied binary at boot, providing modbus support and upgrading to the latest apcupsd 3.14.14 http://alpineapiaries.com/hosted_files/apcupsd-3.14.14-x86_64-1.txz Edited October 26, 2019 by highspeed Quote Link to comment
kyis Posted January 7, 2017 Share Posted January 7, 2017 I just rebooted with the package I just built as well, wish I checked in earlier I wouldn't have had to spawn a VM. I wanted to have cgi disabled anyway so it's not lost. Quote Link to comment
highspeed Posted February 27, 2017 Author Share Posted February 27, 2017 I wanted to confirm that modbus is now supported as of unRAID 6.3.1. They also bumped the build to the latest 3.14.14. Thanks, Lime-Tech! 2 Quote Link to comment

Zangief Posted May 25, 2017 Share Posted May 25, 2017 I managed to get my network card working (following excellent instructions from another limetech user) so have stuck with that. I havent tried to go back to USB MODBUS... Quote Link to comment
devros Posted May 27, 2018 Share Posted May 27, 2018 Did anyone ever get USB MODBUS working? Quote Link to comment
devros Posted May 27, 2018 Share Posted May 27, 2018 Got it working. Didn't know I had to enable MODBUS from the front panel(you can't do it from the management card) Quote Link to comment
