This firmware version is still the remedy even today - I’m using nortek husbzb and hassio z-wave. Thanks for this.
I am using the same setup as you and have been having issues connecting and sending commands to my August Lock all day. Openzwave or Z-wave integrations have similar issues. I can’t believe we have to contact support to ask for a firmware downgrade.
Contacting them now, but also going to keep an eye out for other smart locks…
I got to this thread because I has issues controlling the lock from HA. I contacted August customer service, but they claimed that downgrading FW was not possible. Having said that after a couple of restarts, it appears to be much more consistently. Firmware version is 1.59.0-2.0.1
