Native JS implementation

[mishoboss]

Have you ever considered to use IOPA-ZWAVE instead of OpenZWave? I know OpenZWave is a mature thing, but installing it on different platforms is a huge pain. A JS only solution would be the perfect scenario. The Z-Wave spec is now open and IOPA-ZWAVE seems to implement it. But I've never tested it. Do you?

P.S. This project deserves watching too: https://github.com/AlCalzone/node-zwave-js

I haven't played with either of the JS ones. I had used OpenZWave on a previous project so had some familiarity with it.

I think that its definitely worth looking at.

Great. Crossing fingers those nasty binaries can go away. :)

This is from the current arm docker image. Going to investigate, but the default experience on rb3 seems to be a dead adapter.

edit: just found WebThingsIO/gateway-docker#8 which explains above ^.

After fixing above issue with a temporary symlink in the arm docker container, it now dies with

That means that the zwave adapter is unable to find the dongle. It looks for the dongle by enumerating the serial ports using the .list function from the serialport module. Internally, the serialport module uses udev to determine which USB serial ports exist. Presumably you'd need a way to get docker to know what serial ports it can access from inside the container. I'm not familiar enough with docker to know how or if this is possible.
