Hello, I’m running Hass.io on a Synology NAS. It is installed as a Synology package (not via docker). I am trying to get it to recognize a z-wave stick. Currently, the stick does not show up in External Devices in the DSM but does appear in the “info center” under usb devices.
In order to add my z-wave configuration, what would my path be? /zwaveusbstick does not seem to be the answer.
Going to throw this out there, but a Raspberry PI is pretty cheap and more widely supported… 
I’m curious if anyone has gotten this to work on Synology, but also does the Synology have the horse power to support it?
Yea, just figured I had a Synology sitting around always on and it made sense as a spot to figure out how everything works. I’m pretty sure it’s powerful enough.
You can either SSH to the Synology and use “ls -l /dev/” or try to assume it’s /dev/ttyACM0 and see what happens (That’s the default path on both Synology and Raspberry)
I run HA on docker with an Aeotec ZWave stick. Regardless, the ZWave stick will show up at /dev/ttyACM0. If it doesn’t, then unplug it and plug it back in. It may be at /dev/ttyACM1 if it gets disconnected from the system and will alternate between 0 and 1 each time it’s unplugged and plugged back in.
I was looking for the same kind of information. After hours of hassle I finally found this article, which explains it in detail: https://zwaveguide.com/2020/09/28/synology-z-wave-usb-stick-usage-guide/
Hope this helps you as well.
