Just got my Homey Pro 2023. Attached it to my network, updated the software, and then tried to connect to a ZWave device in my house (GE ZW4003) I follow the onscreen instructions and the Homey Pro gets the “turn on” and “turn off” events, but then I get an error “Something went wrong while adding the device. Could not bootstrap security but unsecure is not allowed for this node.” How do I get this device added to my Homey? Thanks! Jim ---

Seems to be ZWave/Homey issue, if you are on stable rc.110, you can try experimental version rc.118 but I doubt it will help. If Caseda will be reading along, maybe he would know. It’s this app ? [GE Enbrighten App for Homey | Homey](https://homey.app/en-us/app/com.jasco/GE-Enbrighten/) - if so, you may try to reach to developer on homey-jasco@drenso.nl Last option, Athom support (1-2 weeks response time) ---

I’m also having this problem. My Homey Pro is rc122. After testing several switches I found that only the switches that supported Zwave Plus connected. The standard Zwave switches gave the bootstrap error. ---

I’m also having this problem. My Homey Pro software version is 10.0.2 and the device that I ccanot add is PoppE700397. Is there any fix for this problem? ---

Me too! GE Embrighten ZWave (not plus) fails when using the GE Embrighten app, but can be added as a ZWave without the app. ZWave Plus GE Embrighten devices work just fine through the app. If you forget which switch is which, the newer ZWave Plus switches have a QR on the front but the original ZWave do not. ---

> [@chaosrain](#): > > but can be added as a ZWave without the app So, I take it this is the only work-around? Can someone explain to this new user (coming from Vera) how exactly to do this? Thanks! ---

Like this. Add new device, and select Z-wave ![1000049639](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/9/e99108a328f43005597e8734512e27064fe04284.jpeg) ---

Thanks. I figured it out. The fact that you have to push the button twice had me stumped for a while
