Hi! I have bought a DEFARO UZB7 stick which is based on 700 series of z-wave (EFR32ZG14 chip). It is not working with Webthings for me (at all). Z-wave stick addon is added. Any ideas on how to make the connection? Thank you in advance. 😃

We support dongles that OpenZWave supports.

What errors do you see in the log?

Just can’t find any devices with this dongle and there is nothing on my adapters page.

Stick manufacturer asked to install virtual COM port driver. I have some issues installing it (in Makefile it calls `$(MAKE) -C $(KDIR) M=$(PWD) modules` where KDIR = /lib/modules/`uname -r`/build )  
So, I do not have a directory “build”.  
However, I suppose Webthings should support the stick without additional soft.

The virtual COM port driver doesn’t appear to be required. It recognized the dongle as a serial device (which is why /dev/ttyUSB0) was created.

But then the zwave driver failed to start which means that the OpenZWave driver doesn’t know how to talk to the dongle.

This page: [https://defaro.ru/index.php/blog](https://defaro.ru/index.php/blog) seems to indicate that OpenZWave isn’t supported.

There the manufacturer says that OpenZWave is dying technology and with new 700 series chip they are moving to serialAPI to better unleash the potential of Z-Wave Plus. The soft is provided by Sillicon Labs.  
Is there any way to make connection with WebThings using serialAPI (sorry, I am fairly new to the IoT protocols)?

We currently rely on OpenZWave to do all of the comms with the ZWave dongles. I expect that OpenZWave will eventually be updated, but I don’t have any insight as to when that will happen.

So no, we don’t have any other way of talking to ZWave dongles right now.

Which version of the zwave adapter are you currently using?

0.7.5 in terms of Webthings addon.  
Speaking about sticks - nowadays I don’t have any except this (which is UZB7 running on serialAPI).  
Okay, looks like I have to continue with another stick. 🙄
