Migration from C5 to C8-Pro - Z-wave devices not working

According to other posts, this issue has been resolved, but it has not.

I just bought the C8-Pro. I am attempting to Migrate from the C5. Both devices are on 2.3.9.196. None of my Z-wave devices are working on the C8-Pro.

I am using the Migration Tool which creates a Cloud backup from the C5 and then should migrate to the C8-Pro. It pulls all the devices over. However, none of the Z-wave devices work.

Re-pairing the devices is not an option as I have more than 60 Z-wave devices. The only other devices that I have are Wi-Fi. I'll work on those only after I have the Z-wave devices working. No Zigbee or Matter devices.

When you were doing the restore did you check both radios?

Do you have devices listed on the z-wave details page, or is it blank?

Post a screenshot of your red/blue topology map from the C8. I want to see if it is the same issue I have seen with other people.

Also, how is the hub being powered? (see below)

Yes. I selected to options to migrate Z-wave and Zigbee radio settings, and File manager files.

I have shutdown the C-8 Pro, removed the power cable, and then powered it back up 5 minutes later. I am using the supplied power block.

I am in the US. It is using the US 908.4 MHz 916 MHz Settings.

I have a C-7 that I use for testing. I can successfully migrate it to the C-8 Pro. However, the "production" hub is the C-5, so I need all of those devices to be migrated over to the C-8 Pro.

Looks similar to the issue as the other one recently, not sure if they were coming from a C5 or not. The 01 node on the topology has very few neighbors. The issue is that nearly all the devices will be trying route through the devices with the blue in 01.

How long was everything running after the migration? It does take 24-48hrs for everything to settle in. The migration wipes out the routing table so it will be re-established with the new chip and antennas.

I don't think that topology is available on a C5 is it?

This is more what it should look like:

The C-5 does not have the topology option.

Is it possible to reduce the time for the devices to settle down on the C-8 Pro by doing a z-wave repair? Would that update the "neighbors"?

Yes you can try doing a full repair and see if it helps. You may not see instant changes in the topology, not sure how long it takes to update.

I was able to get many of the z-waves devices responding by running a Z-wave Repair. There was some change to the topology, but not much.

You may want to add this to the instructions for the users that have a fair number of Z-wave devices.

I'll wait to see if the rest of the devices start responding. Many of them are older devices. However, if they were working on the C-5, hopefully, they will still work on the C-8 Pro.

Any Leviton Vizia RF devices? I think they have z-wave 100 chips in them. Those are known to have issues on the newer z-wave radios. There was someone just last week who ran into the same issue. Those are really the only z-wave devices I can think of that are known to not work.

The topology may take 24-48hrs to fully update, not sure how it works exactly but the hub needs to get updated info from the devices which is not communicated instantly. Each device is responsible for its own routing back to the hub.

As far as the repair goes, they (HE) don't like to recommend it because it can be hard on the mesh and some people will go overboard and run it all the time. It can cause more issues than it fixes in some cases.

FWIW, I (and others) with as many/many more Z-Wave devices have migrated w/out issues, your results are not common. If I'm reading it right, from Jeff's comment below, your issues look more like a result of a mesh issue than the number of devices.

It appears that I have a defective C-8 Pro. It will not include new devices. When I go back to the C-5, it will see the devices are ready to add within a second of starting the inclusion of the Z-Wave Device. In addition, it tells me that I have a weak Zigbee Signal.

I've been dealing with Hubitat for many years, and have never had any issue including devices. I believe the Model I had before was the C-3 which I gave to my dad when I purchased the C-5.

You can enter a warranty case if you believe you have a hardware issue. I don't have the link handy as I'm out and about but it should not be too hard to find if you search in the forum here or on the habitat website.

Can you post your z-wave details page in it's entirety? Use windows snip.

Change from channel 20 to 25

If there are no zigbee devices, how do you measure the signal?
He could just turn it off.

It's still looking at the channel. Yes he could turn it off, but nothing wrong with simply changing the channel either. Or Click the dismiss button.

Possibly, but not necessarily, when the radio is bogged down with other stuff it has a hard time doing inclusions.

You also never said what your older devices are, they may just not be compatible with the C8.

The Zigbee weak signal message in no way indicates anything is defective. It is something new they are trying out and it only applies to the C8P.

Could there be any excess activity in the Logs?
