Question: Upgrading from AEOTEC ZW090 to Zooz ZST39

[madansu]

Hi !

I am looking to upgrade my ZWave stick from the Aeotech Gen 5 ZW090 to the Zooz 800 Series ZST39
I use ZWaveJS-UI with Home Assistant, with zwave-js-ui deployed in a docker container.

zwave-js-ui: 9.33.0.92d89c5
zwave-js: 14.3.12

My Gen 5 Stick is running -
FW: v1.2
SDK: v6.81.6

For the upgrade, would I simply backup the NVM my old controller, and restore it on the new controller ?

Has anyone here performed such a migration before, and do you have any feedback that might be of relevance ?

Thanks in advance !

I have, and yes, you make a backup of the Aeotec stick and restore it on the Zooz, The only issue I encountered was that the Zooz stick had a US firmware on it, so I needed to explicitly set it to EU frequency after the restore. (Changing the frequency with a config setting is only possible on 800 series sticks.)

Did the migration work? I am trying to do the same migration, but don't want to lose all my connected devices.

If it did work, can someone help guide me a bit on exactly how to do this....so I don't screw it up?

Yes, it worked flawlessly !

Here is the procedure I followed (I run my stack as docker containers with config in the docker-compose file so thats what I'll refer to here. You might need to adapt this to your deployment method)

Step 1 - Backup the NVM on the Aeotec stick. To do so, first navigate to the hamburger menu in the bottom right, and click on Advanced Options -> NVM Management -> Backup, and save it to your disk
Step 2 - Backup the Nodes config file by going to Advanced Options -> Backup (Blue floppy disk icon) -> Export, and save it to your disk
Step 3 - shut down ZWave-JS-Ui container. I also backed up the container files for good measure
Step 3 - Unplug the old Aeotec stick
Step 4 - Plug in the new Zooz stick
Step 5 - Find the device id of the new Zooz stick, and update the docker-compose file with the new id so that the stick can be found
Step 6 - Start Zwave-JS-UI
Step 7 - Make sure the Zooz stick is recognized as node 1
Step 8 - NVM Restore. Navigate to the hamburger menu in the bottom right, and click on Advanced Options -> NVM Management -> Restore (select the file on your disk). This step may take a few mins to complete based on the number of devices you have
Step 9 - Restore nodes file. Advanced Options -> Backup (Blue floppy disk icon) -> Restore
Step 10 - Watch the log to make sure devices are interrogated correctly
For good measure, i restarted Zwave-js-ui after about 30 mins to make sure that everything continues to be good, and then also restarted home assistant

Thats it. Was super easy
