Recent Hubitat user. Have had decent experience so far. Have run into issue where I can’t add Z-wave devices.
I’ve tried all the various troubleshooting steps: reset, shutdown, firmware update (attempted).
Nothing resolves the issues in the subject line. How might I go about getting this resolved?
power cycle is the only thing that resets the Z-Radios.
Do a shutdown again and then pull the power from the wall. Wait 30 seconds (to let the stored power inside the hub drain down) then power it back up.
I have done exactly that multiple times.
So does it work for a while after doing that or when the hub boots back up is it already in a crashed state?
The latter. Already in crashed state.
Thats going to require @support_team intervention.
If you still fall under warranty I would fill out the claim form right away: Warranty – Hubitat Support
I do, thanks! I’ll do that now.
Or maybe not. We can't really help if one or more devices in the mesh are bringing the radio to its knees. Troubleshooting Z-Wave crashes start with the composition of the mesh network. Have there been new devices added to the mesh that are causing the problem? Is one or more devices generating too many events that may overwhelm the radio? Are there ghosts in the system? Finding answers to these questions are at users' fingertips, either in the live logs, past logs or Z-Wave Details page. Where we may need to intervene is when the Z-Wave mesh appears to be healthy (nothing in logs, no failed devices when a Z-Wave repair is executed, etc). In that case, although extremely rare, the problem may be hardware related and the user may need a replacement.
There is no mesh network…no z-wave devices were ever able to be added to the hub. No logs to speak of as a result.
The only Z-wave messages / communications I have received from this hub are listed in the subject line of this thread.
Well, that changes things quite a bit. Please send me a private message along with your hub ID and we will go from there.
We had already determined that even with a power down reboot the zwave was already in a crashed state as soon as it booted. I don't tag support lightly 
. Usually even in the worst cases it works for a little while before it tanks.
