I did a soft reset on both yesterday
I bet that is a copy of the FF LL Stair Switch. I did a Smart Scan install and it didn't take so I excluded the switch and added it manually. Its the blank device you are referring to on Hub 1. Correct? But that's probably still not the problem since both hubs are having the same issue.
Do I need a stick to remove that ghost? I saw an another post where you recommended the user needed a stick to remove the ghost. I have an 18 year old Leviton z-wave stick, probably won't work..lol
I was able to remove it with the app
If it won't remove normally (refresh then click remove on that line)after a few tried, you will likely need a z-wave stick. I would get a cheap one on amazon. They're like 30 bux
That loop went away once I removed the ghost.
Removing the ghost didn't help the connection. The devices are still not staying connected.
Are all 300 of your zwave devices powered up already but just not paired yet?
The devices do not really “connect” to the hub. They just remember the network ID once paired. When everything stops working like this it is usually either from a flooded mesh or a radio problem on the hub. Seems like a flood of traffic on the zwave frequencies might be overwhelming the radio on the hubs.
Can you take one off site and test it?
I shut all the breakers in the house off except for a couple to test. I found that the very first Zooz switch I installed on the first hub, was responding poorly, 157ms, 127 hops, and it 6 feet away from the hub, so I excluded it. Did a factory reset and included it again. Hub one stayed online all day, I going to check it again this morning.
Hub 2 still kept dropping connection, I'm going to trouble shoot it today, keeping breakers off and start stripping off devices. This hub acts very sporadic. Can stay connected for a few hours. Cut out then won't stay more than a few minutes. I can pull it out of the house, I set up a testing switch when I was testing light compatibility, I'll try that next out of the zwave enviroment.
What connection? Z-wave stops working? Or the hub goes totally offline? Please be more specific.
On hub 2, the devices stop reporting and the rules at the switches and scene controllers stop working. I can access the hub, and see the devices and run rules from the app. As soon as the hub connects to one device with a command all devices are back online and work as normally, but then stop after a period of time
Turned on breakers and Hub 1 devices are not connecting again. Going to shut down the breakers again.
I can imagine 200+ devices all sending out discovery frames could overwhelm the hub radio. Especially if they all come online at the same time. Also keep in mind if you are powering off devices you already paired, it could temporarily confuse any remaining online devices since their "neighbors" are now offline.
If you scan the unpaired devices into SmartStart on the correct hub and then power them up in batches of around 4 or less they should pair themselves. Start from near the hub and move out. If you are using mesh (as opposed to LR) then the more devices you get paired it will normally increase the stability.
I can go through and start adding them all with smartstart and then power up each circuit. I am setting them to mesh. Here is the device list again. Just in case it reveals anything new to you
Hub 1
Devices look fine, the number of route changes indicates they are struggling to communicate with the hub. I can run my hub for many days and most devices will have 0 route changes.
I would try to get at least 10 paired to the hub, and with most of the rest of the unpaired devices powered off. Then shut down and power cycle the hub. Test it from there.
You may want to run a full repair at that point too, just so they all re-discover each other.
Those stats will reset when you reboot so you can run it for a bit and then refresh the stats and check for excessive route changes again.
I'm adding devices bit by bit and Hub 1 seems stable now. I want to test it again in the morning to verify.
Am I correct to assume that when not connected to a network, z-wave devices just pound away with radio signals, possibly creating my headaches, but once connected the network they support it and make it strong. It sounds even more obvious as I type. If I do the same for Hub 2 I hope to get similar results.
Yeah basically. They should not be sending out that much when unpaired but when first powered up they will got into pairing mode for a bit then usually give up. However with SmartStart now they will then send out some discovery frames on some sort of interval I think. So maybe with just so many going it was overwhelming.
I checked out Hub 1 this morning and the devices were still connected to the hub and all the rules worked. I can't pinpoint the solution, but I know that adding all the additional devices to the network made it strong. Most of the access times are 1ms or less. The noise for the devices was between 40db and 70db, now it's down to 2db to 5db. I didn't get all the devices hooked to it yet but a majority. I did find some devices that had to be factory reset along the way, they were not connecting or working properly when I tried to include them, they may have been causing problems as well. All in all, Hub 1 seems to be good. Thanks for the help, it take a villages to find a solution.. I'm going to start the same process with Hub 2, hope I have the same results. I'll keep you posted.
On a side note, and this should be for a different thread, I have 26 zooz 4-1 sensors to install that will be hardwired so I can also use them as relays. I saw that there were some concerns about them being chatty, thought I'd ask if there are any setup consideration I should know to set as I install them. Thought it might be easier to set them up right then try to trouble shoot them later..lol..
Check out my custom driver for it, and I have some configuration tips in this post as well: [DRIVER] Zooz Sensors Advanced (ZSE11, ZSE18, ZSE40, ZSE41, ZSE42, ZSE43, ZSE44, ZSE70)
Well, thought It was all good to go, but I got back to the house and all the devices were disconnected again from Hub 1. I don't see anything odd with the devices, but since they are not reporting I can't tell..
Yeah everything looks fine to me there.
Did you click the refresh stats right before getting that screen shot?
