Can't add a Z-Wave device: "We have not found any device in inclusion mode"

Configuration Z-Wave
1

I recently purchased a SiLabs UZB-7 and a Honeywell T6 Pro Z-WAVE intending to use them with Home Assistant. I installed the official Z-Wave add-on & integration, added my Z-Wave controller without issue, and installed the T6 Pro into my house. When I put the T6 Pro into inclusion mode and try to add it as a device in HA, it times out in the T6 saying “Failed to include” and some time later times out in HA as well with the message “We have not found any device in inclusion mode. Make sure the device is active and in inclusion mode”.

I’m sure that distance between my Z-Wave controller and the T6 Pro isn’t a problem; just to see if it worked, I took it off the wall and held it right next to the controller while repeating the above steps. No dice.

I also tried using the Z-Wave JS UI add-on instead of the official one, and while it took a lot more effort to set up initially, once I got it to see the Z-Wave controller and tried to include the device, I got a similar error message.

I have no idea how to go about debugging this as HA doesn’t give me any logs and the T6 Pro is a fairly barebones device without any Z-Wave related options other than “include me”.

Has anyone experienced something similar? How could I go about trying to resolve this?

Factory reset thermostat and try again

I tried that — no dice.

The thermostat does show a node id of 000, so it isn’t included in some other phantom network (I’ve read online this is a common problem).

I use ZWaveJS-UI and what always succeeds for me is to first start inclusion on the addon and then put the device in inclusion mode.

Yeah that’s what I usually do, as the thermostat recommends it. I’ve found that doing it either way (HA inclusion mode than hit ‘Include’ in the thermostate, or vice versa) doesn’t matter, though, it doesn’t work either way.

This seems like a region issue. I have experienced the exact same issue whenever I change the region on my controller. You can only view and change the region in ZWaveJSUI AFAIK.

Edit: Have you tried EXCLUDING then INCLUDING?

Hi, I know this is an old thread, but slondr did you find a solution to this? I have the exact same problem with a brand new T6 that I cannot connect. Any help appreciated.
