C8 to C8 Pro Migration, Recommended practices

That definitely looks better. If you know how to trigger the action on the battery powered device you may be able to force them to start to work instead of waiting for them to call home. Was it just the change to ZwaveJS that helped this move forward,

I had a few battery powered devices I had to exclude and then include again to get to work with ZwaveJS. They were Zen34 remote switches.

What POE Splitters are those. My understanding the Procept ones were the best for the stable power requirements of the Zwave 800 radio

Amazon.com: Gigabit PoE Splitter USB C 5V 3A, PoE to USB-C Adapter, IEEE 802.3at Compliant 10/100/1000Mbps for Raspberry Pi 4, Security IP Cameras and More, PT-ATC-5V : Electronics

I found that any Zwave sleepy device that I could trigger, buttons, motion sensors, contact sensors, etc., all I had to do was activate them at least twice and they would start working.
Same thing happens sometimes when I update hub or even just reboot it. Not as often, but often enough that my wife “knows” to operate my ZEN34 buttons twice when things are “slow”.

These. What POE Splitters are those. My understanding the Procept ones were the best for the stable power requirements of the Zwave 800 radio

These. they have worked fine on the C7 and C8 for a few years. I also have a Texas POE splitter in the clset somewhere. I think thats on my cloud hub. Im not against replacing wih these. I dont have a lot of outlets in there, so I really do need POE for the long term.

I didn't do the analysis but my understanding was that the C8 and C8 pro are very finicky about having consistent power. Brief dipps in voltage causes issues. This is why in so many cases folks are always told to pull the POE splitters from there setup. It is the same reason folks are told to use the original power brick that came with the hub

I believe it was @dennypage that created the thread that finally tested and validated some POE adapters for stability. I would suggest searching for that thread and make sure you got the right ones for the C8 series.

I know many UCtronic POE Spitters didn't cut it. Even the lower price Procet one didn't. It doesn't mean they can't work, just that it is risky since their voltage seems to fluctuate to much.

C8 Pro, I believe has a bit more draw..

To be rock solid you could get the PT-PTC-AT one. It is a bit more pricey, but was considered the best I believe. It is actually what I run on my C8 Pro and has been rock solid since I got it.

FWIW, I've used both the PT-PCT-AT and PT-ATC-5V w/out issue on my C8-Pro:

FWIW, I pulled the trigger on the C8 to C8 Pro migration just a little while ago and so far everything is working without a hitch. I did get the "Weak Zigbee channel found" message for running on CHN20, level 8, but dismissed it based on threads I've seen.

I made a last cloud backup, shut down, re-swizzled my DHCP reservations so the new hub came up on the old hub IP and just did the prompted cloud restore.

I've been down the power issue road before so went into it with every intention of using all the as-shipped parts (well i did use different high gain antennas).

I'm going to let things settle just a bit before I re-enable all the internet integrations and go through any re-auth needed.

It's also still running the as-shipped firmware (the C8 was on 2.4.3.133).

So are we leaning into declaring victory? :wink: :slight_smile:

Or dast I speak too soon... :scream: :open_mouth:

Too soon. Seems llike everything has stalled out,, most motion and contact sensors, including all battary powered LR stuff is still pending. So very few automations workng, anf the frew that are involce matter devices and a very high traffic zwave motion sensor (Under the desk wehre im doing all this).

As noted previously, I believe, they (battery devices) may just take a little longer. The overall table looks good for mains powered devices except maybe on, I think. :crossed_fingers:

I just went through and woke up a few. There are a few that aren't all that convenient to get to to hit the button. Add to that they are Zooz ZSE70's, and almost every time I have to take one down the housing is so tight the mounting clips get pulled out and I need to request a new one from Zooz. They have been great about sending replacements, but this will be like the 5th one. It's just a bad design that needed either re-enformcement or made frm thinker material.

Starting to lean towards another fail . Concerned there still seems to be an issue with Zwave LR devices not checking in . and even the mains devices , while showing a last message, dont seem to be responding


Summary


> Blockquote

Is it still using POE for power?

Did you reboot it again since the previous screen shot. It looks like the hub was rebooted as some devices that had last message date and time do not in the most recent screen shot.

When you say it isn't responding do you mean if you initiate a change form the hub it doesn't happen. What happens if you flip the physical switch and it turns on/off. Does the update get back to the hub?

Nope. Plugged in directly with the original block and cable.

Yes, Was think if I did a rebuild database on reboot it might help it along.

Correct. Plus plenty of motion sensors flashing they they sensed motion (been walking around all afternoon doing stuff) but nothing shows in logs, and the autiomations they are supposed to trigger arent firing off.

on the mains devices, its about 50/50 some it is registering, some its not. battery devices , no. even if they have a check, route and last message.

Darn that was a really good bet for possibly being the cause.

I suspect it probably didn't help since I believe the Zwave stuff has it's own DB. Was it just a reboot, or was it a shutdown, remove power and wait 30 seconds and then power backup.

May want to try that to see if that helps with devices not responding.

Just a reboot.. i can tty a power pull..

Seems like the powerpull may have helped. Still a bit flaky. I need to get up early tomorrow, im going to let it cook over night and see what it looks like in the morning.

Thank you to all who have been so helpful today!

Just another PoE splitter data point…. The UCTronics PoE splitters are not reliable when used with the C8 and C8-Pro hubs. They works “mostly”, but they really are not reliable. Best to replace it with one of the ones that were tested to be robust and reliable.

Everything is stable and running well. Had a few speed bumps getting Echo Speaks cookie to refresh but finally got it going. Had to uninstall/reinstall the mobile app to get it to pick up the new hub instead of the old, but that could be because I re-used IP (DHCP res) and renamed hubs back and forth. Account registration didn't seem to have any issues with that, but the app certainly did. Found a few ZigBee motion devices not responding but those turned out to be be weak/dead batteries (my bad) and they added right back in like they always do if they go offline/dormant for too long. No issues with any other services, Rachio, etc., Went through each and no login or connectivity issues.

Looks like I can just move the hub protect sub online (it does clear cloud backups) so that's next and I shouldn't need to bother @bobbyD for that. That, getting a fresh backup, putting the latest beta back on, and a final reset on the old hub should wrap things up. I suppose I should find a home for the 2 C5's and C7 sitting in a bin as well. Think I'll hang onto the C8 for a spare.
