Question about "Product name collision" in z-wave log

I’m having good results with Hass.io 70.1, with 6 door sensors, 4 switches, 4 multi-sensors, a thermostat and a few web-based sensors. Loving it. But I’m struggling a bit with my garage door opener, but I’m hoping that I’m getting close. The opener communicates fine and I can see the statuses, but no switches are exposed. I believe I see something interesting in the log, but I couldn’t find details when I searched for a solution.

Config: Hass.io 0.70.1
Device: Linear GD00Z-4 Garage Door Opener Remote Controller
Node ID: 6

When I refresh this node and check the z-wave log, I notice that I am getting “Product name collision” messages with the opener’s switch. Log details:

I didn’t find any information on whether a “Product name collision” was fatal or just a warning.

Otherwise, I suspect that the device is communicating fine, since I can see the attributes of node 6:

I’ve read older threads about the Linear garage door opener, which included building or patching a custom openzwave library, but I’d prefer not to get that deep into the weeds if avoidable, and I’m not even sure that applies to hassio. Any suggestions are appreciated, as always. Cheers, Kevin

In order to operate the door remotely you have to install either the custom openzwave_python via github or use the pip command to install the ozwdev flavor. There is no other way.

As for how to do this on Hass.io I believe it was already posted in the zwave section thread.

Thanks, I’ll check this out again. Appreciate the feedback.
