I literally just got on here looking for support for my ZooZ double plug. It pairs (after a bit of lag) just fine using S2 unauthenticated but does not respond to switch commands, and eventually just ends up as "Failed". I was able to update the various reporting frequencies to like 1h each and it works. It's just the switches are not able to turn on/off. It seemed to freeze up at one point (even ignoring hardware input)...
I'll try to join it without security and see if that helps. Glad to share logs, etc.
Edit - no dice joining without security (Though I have never been able to get any of my other Zooz devices added without s2). Looks like the logs did dump a bunch of "debug" data on the device though. Going to leave it out of the network for now.
All I get for configval18 is 4 as well. I tried the Basic ZWave Tool but it didn't seem to do anything I tried the parameter report for 18 and nothing and tried putting 18-1-1 in the fields to configure it and it didn't appear to do anything. I did check and notice there was an updated version of the tool so I updated but had the same results.
When you try the parameter report don't put in a parameter value, just click on that command and you should get a full report for the device in your logs, and you'll be able to see parameter18's value in the list of parameters.
So I would say it's not just the Double Plug that has issues when paired with S2 security..
The Zen 23/24 switches and dimmers seem to have this as well though maybe not to the level of stopping the mesh.
It's no issue for me as I have been pairing unsecured but others have been reporting trouble.
Note: I did try and pair S2 unauthenticated and got a ghost so maybe slightly different issue OR the Zooz engineers are doing something different (in general) with their devices than HE expects...
It's a custom driver you temporarily replace your devices driver with and it will allow you to query and set parameters for the device. When done simply set your device back to the original driver. Very handy.
As @erktrek notes - get that driver and install it.
Then temporarily change your Zooz double plug device to that driver. Then you can access those controls to view/set your parameters. Then switch back to the regular Zooz double plug driver. Sorry - dupe of above.
Same...the entry on the Device page below, correct? If so, don't worry about that for now - it seems that the displayed parameter values there don't get updated properly/quickly. I updated mine, verified in the logs early this morning. But mine still says 4 on the Device page. Hopefully when the work week starts @bobbyD can confirm.
The Zen15 also has issues with being paired securely. It doesn't take down the mesh (that I can tell) but it doesn't report power. Power reporting is fine if paired unsecurely though.
On my C4 don't see an issue. All power reports are off. The plug was fine on ST, so I'm guessing something with the new 700 series firmware and the plug
I'm not blaming anyone, except maybe silabs. The 700 series seems to have lots of "quirks". This is one of the times I am glad I still have a C5 in addition to the C7, and that Hubitat didn't "upgrade" that C5 Zwave firmware.
