Z-wave help

I am trying to track down a recent slowness in my zwave network and could use some help. I did send an email to support but want the opinions here as well.

A little background, I my z wave network is 20 devices around a 2000 sqft house, all z-wave plus and installed over the last couple weeks. The network was working fine until last night the living room dimmer wouldn't work from the app. I ran a z-wave repair and found the several nodes failed The only change was the I moved a Zooz power strip from the mantle up about 2' onto the well. Where do I start to track this down? Is the answer additional repeaters?

Yes.

It has been said many times and in many threads that a z-wave repair is not the option to take if you have a node that doesn't want to play. It can cause more issues than it solves.
I appreciate it's too late now but a better course of action is to concentrate on the node that is playing up. If everything else is working OK, why touch it?

Hope you get your issues resolved though.

Try rebooting your hub - Settings>Reboot.

If that doesn't help right away, try waiting a little while. If you give your system some time it could resolve the routing problems, particularly if you have Z-Wave Plus devices.

Moving the power strip 2' should not have a significant affect on your mesh. Did the Zooz get moved behind something like a TV or other enclosure? Is your power strip accessible from its Device page? If it does respond to on/off, unless you have a need for power reporting, turn off or set to lowest level all power reporting on the Zooz power strip. Sometimes power monitoring devices can be very chatty which can be a drag on your mesh.

Post a screen shot (may take several screen shots) of your Z-Wave Details page.

Tried a reboot last night and it hasn't helped. The power strip was moved up behind the TV and is showing measly speed of 9.6 kbps. This morning I went through all the devices that report power and set them to only report on a change of 10 W or more. Removing the %change, every X minutes and energy reporting. I can get screenshots later today.

as i have found out.. not good to put a device blocked by metal.. if anything is attempting to route traffic through it . that can cause your issues.

So that could be it...power strip is now in a "Faraday cage" and can't get decent speeds to hub. You may need to put a Z-Wave repeater where the power strip was originally so it has a better way to phone home.

Also, your other devices may have been/still are trying to route through the power strip, which results in more problems.

That was a concern of mine, I placed a plug in smart switch that should repeat in the socket directly the power strip.

Unfortunately the power strip has to go behind the TV..

the mesh may eventually stabalyze as devices stop using the strip.. check the zwave details and try doing repairs on anything using the strip as a repeater.. do node level repairs on those.. you may have to temporarliy turn the strip off during that.. in addition you can check the new route the device takes by hitting refresh after the repair and looking at the zwave log.

does anyone know if there is a strip out there that doesnt repeat or allows you to turn that fx off. that would be optimal..

That should help over time, but the funny thing about repeaters is that sometimes your devices will just ignore them, can be very frustrating.

In the end you might have to exclude the Zooz strip, let your mesh settle down/route w/out it, and then re-include it. That way hopefully devices won't try to route through it if it has a marginal connection.

Interesting question, but I've never seen any Z-Wave device w/a "don't repeat" option.

how about a wifi strip. i know tp-link/kasa wifi devices are good..

this is what you should be using instead.. wont affect your zwave mesh.

Kasa Smart HS300 Plug Power Strip, Surge Protector with 6 Smart Outlets and 3 USB Ports, Works with Alexa Echo & Google Home, No Hub Required - - Amazon.com

there is also a kasa app in hubitat i use.. should be relatively transparant.

There is an HE integration for that?

yes

Iโ€™m really only using it for power sensing. Maybe thereโ€™s a WiFi device that would be better for that.

The Kasa is wi-fi, and you can also integrate it - best of both worlds. :slight_smile:

Cool...somehow I did not know that. Are you using any Kasa devices w/the integration?

i have switches on my dashboard for them.. also power monitoring on another dashboard. and everyone should have one of them on their hub so you can reboot the hub especially if the house is empty at times..

i also have an att access point as a backup with a kasa on that on my cable network and another kasa on the att network so i can reboot the main cable network if we are away and it goes down.. I have had to use it at times and sometimes they tell you "reboot your modem"

And in HPM!

I assume from the subtext that the top one is cloud based and the bottom one local. Cloud-based get's you remote access (w/out VPN or other option)?
