So, I just unpack my ZWA-2, connect it to my HASS and it got recognized, I installed it following the wizard to setup a new Z-Wave network and everything went just fine. A few minutes later I got a firmware update to ZWA-2, I hit the update button, it started doing the firmware update and when it finished (I assume it finished installed since I wasn’t looking into the interface) it state the device was offline… I wait for a while but nothing happened… so I waited a bit more and then I check the logs of Zwave-js and I found the following message:
