The only buttons I have on top of the Z-wave details page are: exclude, repair, Logs and topology.
I don’t see anything out of the ordinary in the logs either. I do have a couple of older Z-wave switches so I use “polling” and that is by far the biggest activity but that has been there since day 1 and only recently have I seen the issues.
I’ll keep an eye on the devices themselves too. I don’t see any obvious misbehaving devices (but I think the stats all reset when I shutdown the hub so will monitor over the next few days).
I had this occur today. All of my devices were missing under z-wave details and the hub said z-wave is unresponsive. Reboot didn't fix it but shutting it down and physically power cycling it did.
I was out of town for a couple of weeks so this was very unfortunate.
If you have a wifi plug feeding the hub, you can safely shut down the hub using the Settings page, and then power cycle the hub. Good if you're out of town, the hub is in a bad spot, or you don't want to get off the couch.
This occurred for me today. My Z-Wave was down. I was on 146 until 6/25 and didn’t have any up issues then. Could 152 be exasperating this? I have my cloud backup weekly (until today).
Mt charges are infrequent, so I changed local from daily to weekly and cloud from weekly to monthly.
When it does that (if the zwave 800 NVM backup is like the zwave 700 NVM backup, and I think it is) the radio actually has to be stopped/restarted. If that doesn't go right for some reason, the radio could get into a weird state.
