I am having trouble with Homey’s z-wave. I think it is not working anymore. I had Homey working with an Aeonlabs multisensor 6 for 6 months, when I bought an Qubino smart switch (ZMNHYD), two days ago. For this switch I needed to install the Qubino beta app, since this one only supports this switch. Install of the switch was started, but hung. I saw a long line of (I think) text referring to the zwave module in Homey’s OS, I guess? Trying again won’t find any module, at this point I see that the Aeonlabs sensor is gone, too! The scenes using this sensor show a broken keychain… Tried many things, such as remove the z-wave device, but no devices to remove, reset z-wave, set Homey back to factory defaults, again, upgrading to the beta, all without any result, no z-wave anymore. So, what I think needs to be done is flash the original Homey OS, so I can see if it is a software or hardware issue. Any ideas of how to do this? Thanks… ---

What do you mean by original Homey OS? What version firmware is Homey running now? ---

thanks for anwering, Yes, of course I did. It’s the procedure where one puts Homey upside down for 10 seconds, right? ---

I mean the firmware, but, that is the OS (Operating System) in some way, right? Homey Firmware Versie: 1.5.13-rc.11 ---

I was not aware that the quibino device could be reset. How? ---

Tried the procedure (press button 5 times within 3 seconds), but the device gives no visual feedback or something, so how does one know it worked? I tried then to discover the Quibino again, but nothing detected. As said before, I tried to discover the Quibini and also the Aeonlabs device but both are not seen anymore by Homey. Isn’t there a way to do a “self” test in Homey, to discover if z-wave is working properly? ---

Maybe check the [developer tool section](https://developer.athom.com/tools/zwave)? ---

Reset homey, do not keep your settings and press the Alt when you continue to choose to rollback from expeimental to the latest stable firmware. [https://www.athom.com/support/KB000026/](https://www.athom.com/support/KB000026/) But you can’t go back further like the one your Homey was delivered with. (Believe me, you don’t want 😉 ) ---

Clicking with Alt pressed results in nothing, I see that the text in the button changes, but that’s it, so tried clicking without Alt, and the procedure continued… No have to wait for the download to finish. ☹ But this is the previous software version, so at least that is better than the experimental version, I think. Will try again when finished… ---

Okay, thanks, I am back at firmware 1.5.12 now. I managed to re-add the Aeotec multisensor 6, but only after resetting the sensor. At least now I know that the z-wave of Homey still works. The Quibino smart switch still does not work, so I guess it is faulty, I am in contact with Quibino for that. Thanks all for helping! ---
