How many Z-Wave devices do you have? If that number isn’t huge, building a new network with a new stick is what I did when I moved over from HS, and I’m quite happy with the results.
Assuming your existing Z-Wave network performs well, if you don’t plan to physically move your Z-Wave controller I would simply turn off HomeSeer and add the controller to Home Assistant. Home Assistant will import all your Z-Wave devices automatically. You will need to know the security keys from HomeSeer and translate them to the format Home Assistant needs. If you are using HS4 and have S2 devices, the S2 key is encrypted so you will need to extract the unencrypted format before shutting down HS4. Print out the Z-wave node number table from HomeSeer as well so you know which node is which as the names won’t come over to Home Assistant.
Depending on how many Z-Wave devices you have and how many are battery powered it could take a day or so for everything to populate. You can speed things up by waking up battery devices and re-interviewing them.
Be sure to use the Z-Wave-JS-UI Addon and not the Z-Wave-JS Addon. Your only choice for Integration is Z-Wave-JS (yes, similar names but different software). You need to add your existing keys to the settings in Z-Wave-JS-UI.
Home Assistant doesn’t make any changes to your Z-Wave controller so you can switch back and forth if need be. You can only have one software connect at a time, obviously.
I moved over 2 years ago from HS3. No regrets. Home Assistant has better documentation and a better forum platform by far, not including the many helpful forum members. Just double check any posts over a year old as things change quickly. 
Feel free to ask any conversion questions there are a lot of previous HomeSeer users here.
Thank you for the replies!
I probably have about 30-40 devices through out the house. It wouldn’t be terrible to remove them and add them back if I need to.
Firs, I think I’m going to look into finding the keys in HomeSeer and see what the lever of effort is in comparison to recreating the network. I don’t plan on ever going back to HomeSeer so I don’t know that I need the option to switch between HS and HA.
I’ve already noticed a lot of previous HomeSeer users here. I expect there to be a lot more given the current state of frustration in the HomeSeer forums.
If you do take one of the “build a new Z-wave network” options, the recommendation is to start by adding devices that are close to your controller stick, and then moving your way out. This will help build the most robust mesh z-wave network as you go.
Thank you for the reminder. I added several new devices at once a few years ago and end up having to rebuild using the method you mentioned.
I tried using Z-Wave-JS-UI and adding the keys I got from HomeSeer. However, it doesn’t seem to be working correctly. What I see when I connect to Z-Wave-JS-UI via my browser is below. Does anyone have an idea what may be happening?
How long ago did you move the controller over? Are nodes 4,5,6 mains powered or battery? What does the debug log show for Z-Wave-JS-UI?
Battery powered devices will have to go through a wake-up interval before they are completely updated unless you wake them and re-interview them manually.
I moved it over about 30 minutes ago. I’m not entirely clear what nodes 4 and 5 are when I check HomeSeer, but node 6 is a main powered light switch.
In general, most of my zwave devices are main powered. The only battery operated devices are my door lock and door sensors. Currently every device I have is showing as unknown.
You didn’t mention the log file. I would recommend reviewing that as you progress. Assuming the log shows no errors, open the hamburger menu, open general settings (The purple icon below) and select Re-interview nodes. This should update the mains powered nodes immediately, and the battery powered nodes as they wake up.
I tried reinterviewing, but it didn’t work either. I checked the log file and it is full of statements similar to

hi,
After 15 years of HS, i moved from hs to ha recently. Nearly everything is fine, a lot of technologies are suported and working well, even my car, but i am still not able to see my z-wave devices in ha. i am using Z-wave JS-UI, and i see all devices in the z-wave interface but have found no way to get these devices in HA.
I followed the wikis and all i could read about Z-vave JS and z-wave JS-UI.
It is all very confusing to me.
Maybe you can set me on the right track ?
regards
Claude
You controller doesn’t appear to be communicating with the nodes. Are you sure you converted the keys correctly? Are the controller and nodes still in the same physical places?
I’d move the controller back to HomeSeer and see if everything works. If so, you have a configuration problem in Z-Wave-JS-UI.
Got to Settings > Devices and Services > Z-Wave. Then click CONFIGURE. Post what the integration configuration settings are.
Get here, click CONFIGURE
Then post this:
Also, you should take this to a new topic and not piggyback on someone else’s.
I think you are right about the controller not communicating. I’ve followed all the steps to convert the keys (add a 0 before any single characters and remove the dashes). I also haven’t moved any of my devices or the location of the controller.
Currently, the controller is connected back to HomeSeer and everything works. Outside the keys, any suggestions on what I should look for in the configuration settings?
Configuration :
i am using Z-wave JS-UI because i can set the port as a remote serial port. HA is installed in a virtual machine.
And i get all my devices ok.
About 3 weeks ago I moved one of my systems from Homeseer to HA, I have only about 30 zwave devices (switches are mostly UPB), I bought a HA Green box, a new Zooz long range 800 controller stick and excluded each zwave device individually from Homeseer and Included them into HA Z-wave JS-UI . This made for a nice clean install and the new stick is much faster/longer in range than my older HS smart stick. You might want to get the new controller stick and start from scratch.
You have both the Z-Wave-JS and Z-Wave-JS-UI Addons installed, which is widely discussed as not supported. Read the docs again and remove the Z-Wave-JS Addon.
You didn’t post anything from the Z-Wave-JS integration, which leads me to believe maybe you don’t have the integration installed, which would match the symptoms you describe. Review the Home Assistant docs and make sure you have a good understanding of the basic concepts. This block diagram may be helpful Z-NET Integration with HA - #78 by mterry63 it’s not entirely the same for your setup but the HAOS block is the same.
When you select the Devices and Services menu option, does Z-Wave show up in the list of integrations?
After hours of messing with the HomeSeer SmartStick I finally got most of my devices to show there values. Once everything showed, I was able to see a few issues, such as most devices being routed through a non-zwave+ power strip in my network closet. I ultimately decided I was going to just reassociate all my devices and order the new Zooz long range 800 controller stick.
When I add all exclude my devices from the older network and include them in the new network, is there a way I can prevent my devices from being routed through the non-zwave+ power strip?
My thoughts are to add all my zwave plus devices and then add the power strip. Would this accomplish what I’m wanting>
