Could Modem Re-boot Corrupt/Disable Z-Wave mesh and/or hub or switches?

My current setup:
C7 hub running 2.2.7.126.
Approx 23 Inovelli red dimmers with firmware 1.48
5 Inovelli black switches with firmware 1.20
5 Inovelli fan + light switches with firmware 1.36
2 Aeotec Range Extender 7s
2 Aeotec Smart Switch 7s
1 Aeotec NanoMote Quad 7

While I had just done a post elsewhere about how every now and then it would take about 30 seconds for a light to respond to a command that has to go through a rule (vs. a switch that directly controls a light) I suddenly have something much, much more serious going on.

All of a sudden many lights are responding either extremely slowly or not at all. The only thing that I can think of that happened yesterday is that my cable company rebooted my modem when I was activating a cable box replacement from them. I have my hub at a fixed IP address, so I don't know why that would have any effect at all, particularly when I press the physical switches.

Except for one of the fan + lights, pressing the main physical button does turn on/off the lights (and fan if applicable). For that one fan+light, pushing the physical button does nothing and I don't see it registered in the logs either. I do have another switch that only has a main and neutral that is supposed to control that fan light too. When I push that physical button I see see the LED turn on/off, but it doesn't turn on the light either.

Here is a screenshot of the log when I push the hall side switch that is only connected with a line an neutral but is supposed to turn on the light portion of the fan+light:

When I use the config/favorite button on the other Inovelli red dimmer switches (which has to be controlled by a rule) at first they weren't working at all either, but now they seem like they are working.

When I tell Alexa to turn lights off or on it may work or may not. What's weird is that Alexa will say usually "ok" but then nothing happens. Here is a screenshot of what happened when I told Alexa to turn off my den light - She said "OK" and, as you can see, an off command appeared in the log, but it didn't turn the light off.

What is also weird is that I had that light on and when I tried to turn it off via the dashboard I also saw a log event, but just got the hour glass. After a while the hour glass went away. When I tried it again it worked. But, I just tried it a third time as I was typing this up and, again, it is just sitting there with the hour glass. Here are the screenshots showing the press was recognized.

Just for comparison, I was able to get the light to turn off from the dashboard when I tried it a 4th time. Here is a screenshot of the logs for when it worked with the dashboard:

Anyone have any idea what is going on and how to fix it? Any idea why the one fan+light isn't working even from the physical switch? (And, BTW, that switch is in the same room as the hub, so it certainly can't be a distance issue).

BTW, I did do a controlled shutdown of the hub. After which I unplugged it and then plugged it back in and brought it back up, and that didn't help.

Like I said, I didn't change any rules or software or anything for days and it seemed fine yesterday morning (except for the random 30 seconds delays mentioned above - but nothing like this almost complete collapse.) But, how could rebooting the modem affect pushing the physical buttons and rules that go through physical buttons?

Start with the basics... Do you have any ghosts in your z-wave table? Do you have any zooz products?

If the answer is yes: Remove all ghosts and re-pair zooz products (mainly the zooz 4-in-1) with no security or if you have the double plug, upgrade the firmware and lower power reporting intervals

If the answer is no (or this did not completely solve it). Download your current database to a computer. Go to yourhubip:8081 and do a soft reset. Restore your system with the backup you downloaded prior to the soft reset (this ensures a possibly corrupt database is cleaned up)

In either case before anything shut down your hub from the settings menu then unplug power (at the wall not the hub) for 5 mins, then power back up. This will ensure clearing of the radio.

Try those to start

No ghosts (I checked my Z-Wave table and Devices)

I don't have any Zooz products

I had done a controlled shut down, pulled the plug for about a few minutes (not sure if 5 min) and then powered it back up. I did not do a dl' then reload of a backup before I shut it down.

BTW, I "air gapped" the one switch that wasn't working at all, an Inovelli Fan+Light. I saw that it did have power before I air gapped it (LEDs were lit up) and when I pushed it back in they flashed green, red and then blue again. I waited a few minutes and then tried to turn it on from the devices page. That worked. (Woo hoo!). I then turned it on and off from the switch in my outer hall which is an Inovelli red dimmer in hall that only has a line and neutral attached to it. (So it works totally via a Hubitat rule). That worked too. Woo hoo squared. :slight_smile:

So, at this point I think I will let it sit overnight and see if it all gets restored. If not, I will then do the dl, shut down, re-boot, reload routine. BTW, the way you wrote your response it reads that you suggest I do a dl, reboot, and then load the database that was just downloaded. Do you mean that or should I load a backup from before that download? It seems if the database got corrupted, if I dl' it and then reload it I'll just be reloading a corrupt database, even if I have rebooted the system. But, I've never reloaded a database so I'm not sure which is the correct procedure. I know I did do a dl' just before I upgraded to 2.2.7.126 from 2.2.7.123

Also, BTW, do you suggest pulling the plug from the wall vs the hub because the hub plug is fragile or for some other reason?

Thanks again,

Stuart

download latest config to pc
go to yourip:8081
click soft reset
after restart you will see the option to restore database. Choose the backup you saved to your pc prior to soft reset
after everything, shut down from settings menu. Unplug at wall for 5 mins and power back up. See how things go (this will ensure a clean database)

Another thing is to disable all 3rd party apps then enable one by one

Actually, it’s that the solder joints between the miniUSB socket and the printed circuit board are known to break.

Excuse me for repeating this and being dense, but I'm still a little bit confused about the reboot procedure. If I dl the latest config, do a soft reset then used the database I just dl'd as the restore, if the database was corrupted then won't I just be reloading that corrupt database?

I don't get how reloading that database, then doing a shut down, unplug, etc. would fix things.

No. Downloading the database actually cleans it up and reogranizes it

Great. Understood. Most everything is working so I hope it is possibly cleaning itself up. For example, a light switch that was only connected to a line and neutral didn't turn on the light it is supposed to activate this morning (although the LED went to 100%), but did a bit later in the day. If the problem persists I'll do the described routine.
