My hub has gone through 2 abrupt power outages in a little over a week and has grinded itself down to a stop. Commands are taking up to 5mins to respond. Even zwave association has taken up to a minute.
The first power outage was a new ISP came in and setup my new connection. He unplugged the hub to plug in the modem. When I rebooted my entire zigbee network was gone (15 thermostats, 5 plugs). I restored from 2 known good backups and the devices still weren't there. So I went around and re-paired them all. It actually took 2 or 3 attempts at each device to get them to pair again.
Monday of this week we had a power outage. Lasted about 3 hours. This is where my massive slowdown started. Reboots don't do anything to help. I've run a few zwave repairs and they're taking about an hour to finish.
I’d try a restore and see if that works. But, do you have a backup from before the issues? If not, well, you know. I automatically archive mine nightly.
Before the outage was meant to minimize corruption from the power outages. Did you have a backup? It could be a device, mesh strength, some app or device driver, etc. These are the things in our control. Try one by one.
Just sent off an e-mail to support a few mins ago. I'm sure they're just going to say remove all custom apps & drivers. But I've had those apps and drivers since day 1 and the issue just started with these outages.
Interestingly, I did a full shutdown on the hub. When I hit the light switch at the top of the stairs the z-wave associated devices triggered instantly like they always had. Powered the hub back up and they were back to almost a minute lag. There's another thread where people are talking about stranded/ghost devices clogging up the mesh, I'm hoping this is my issue and there's a quick fix for it.
Bobby has never told me to do so and I have custom apps. Shouldn't automatically assume that't what they're going to tell you. I'm sure he'll take a look at things and advise accordingly.
I really don't like to be the bearer of bad news, but your wish came true Also check your lan connected devices, as some appear to no longer communicate with the hub. The following post is a good summary of your options for the night. I will reach out to you via email or PM, whichever works better for you.
The LAN devices all got new IP's with the new ISP, and I restored a backup from the day before so I haven't gotten in to change them all yet. I'll get that all straightened out again tonight.
I remember having to deal with a ghost device once on ST. It was as simple as creating a new virtual device, assigning it the same device ID, selecting a z-wave driver for it and then deleting the device. I'm hoping that process will be as simple here.
No need for that. The nightly task will remove those automatically. If you could power off any devices that don't exist on the Devices page, or otherwise failed to pair or you no longer use, that would tell the radio that they are dead, so the hub will remove them tonight. Let the hub do its thing tonight and we can look at it again tomorrow. Things may be rocky for the next few days, but we will get you straight.
I don't know exactly how the restores work, but if the database of your backup is good, and the process of restoring it isn't jiving with the current corrupt database, a full reset SHOULD correct the database corruption allowing you to do a restore. BUT, you may have to pair all your devices again?
Maybe do this as a last ditch attempt and see if others have better suggestions.
Please be careful when using the R word. With "Full Reset" you cannot restore as it resets the radio. The link you shared is correct and it is for "Soft Reset" which accomplishes what you have described, with the exception that you don't have to pair devices again.
Interesting to know that and thank you for the clarification. I tried looking for some more detailed documentation, but there doesn't appear to be anything referencing the Full Reset specifically. I've seen Soft Reset used differently in the IT field. Usually just refers to rebooting a device, or something similar without clearing out the settings.
Actually, something else just occured to me. @MRobi said the ISP replaced the modem. Does that mean you have a new wireless access point as well? Maybe the new device is using different channels than were previously used.
The wireless settings could be screwing up your Zigbee/Zwave mesh and causing the delays. Try changing the wireless radio to a different channel to avoid interference.
@cherbein03 I use ubiquiti gear for all my networking. The ISP's modem has the WiFi disabled and once I get my hands on a UDM-Pro I'll be taking their modem out completely. Good thought though!
@bobbyD has me firing on all cylinders again. Things are back to normal here. Had to re-write a bunch of rules I lost from the restore but that's certainly better than starting over.
With all this extra time on my hands these days I may even experiment with bringing my Schlage locks over from ST.
LOL I figure everything else is running smoothly and they're all that's left. Might as well experiment
I've looked at UPS' several times and then never pull the trigger once I see prices for what I'd need. My media server is a beast and then with everything else in the rack I'd need a 4,000w UPS at a minimum. And those run around $3k.
Understood, so set it up to shutdown safely. I have a similar rack setup as you, but no where near 4000 watts (my equipment is new and energy efficient).
