Z-wave - Add Controller with existing devices?

I have a Z-Net Z-wave controller from HomeSeer that is currently in use by HomeSeer’s HS3 software. If I shutdown HS3 and create the appropriate device/connector in HASS can I add the controller and devices already imported into it in Home Assistant? I realize all the devices may not be recognized, but is there a good reason to Exclude/Import devices into the same controller?

It seems from other threads here that people are successfully using the Z-net as a Z-wave controller in Home Assistant, so that hurdle isn’t an issue, and I’ve seen instructions on how to add the ser2net configuration to correctly connect the device.

Have any other HomeSeer converts given this a try?

Are any devices includes securely? If so, you need the encryption key from Homeseer.

Are the devices all supported my zwavejs? Check the database.

Thanks for bringing up the encryption key, I do have that, converted to the format HA wants. I’ll check the database on my devices. Does that fact that a device is listed in the database mean it’s supported?

Usually, yes.
I had one device that was incorrect in the database but was able to work to get that corrected.

Well, I’ve learned a lot about HASS OS and Home Assistant over the last couple of days. :slight_smile:

I was able to create a link to /dev/ttyS0 with socat to my existing Z-Net Controller, and add it to Z-Wave JS in Home Assistant after disconnecting it from HS3. HA spent about 15-20 minutes interrogating my existing nodes that made me sweat, but in the end I think it’s all OK. It imported all the devices, some good, some not. I’ll sort through and see what is what. I suspect the devices that are unknown are battery powered and just haven’t woken up yet. This was just as test run so I shutdown Z-Wave JS and went back to HS3. I had to restart HS3 to get Z-Wave back, but it seems to be fine. The Z-Wave controller seemed to be recognized and used just fine as an EZZee by Express Controls, which is the correct device. At this point I don’t think I’ll have to exclude/include devices to change software. More research to come!
