[RELEASE] Zooz Power Switch / Zooz Smart Plug

(Warren) #266

It’s basically the same issue I reported a few months ago:

This was of course with the old firmware and old DTH, so nothing new but for sure an (minor but annoying) issue I would say. Someone should bounce this off of Zooz.

@krlaframboise, while I don’t think it has anything to do with the 3200 message warnings mentioned above, one thing I noticed with the newest DTH and/or firmware is that the voltage value seems to be incorrect and offset, in my case, by about +15 volts give or take - not sure about the other reports but the voltage was obvious though the current and power reading are suspect too since absolute 0 seems unlikely (idle sump pump).

I thought that it was just a bad plug but I have several and I measured the voltage with a bench instrument just to be sure. I don’t think it is the new DTH per se because the Zooz switches that are on the old 1.2 firmware with the new DTH report the correct voltage but what I was thinking was that maybe it was the combo of the 1.3 firmware and the new DTH meaning the message changed or something. But, in an oddity of a data point, when I went to a device that had been upgraded to the 1.3 firmware, the voltage in the ST app showed correctly and for the firmware version number it showed “- -”. I then went into the settings, changed a couple of things and saved and then, snap, the firmware showed as 1.3 and the voltage changed upwards of +15 volts a few seconds later.

Maybe this is a support question for @TheSmartestHouse if it’s a pure firmware issue since they’re the US agent for Zooz.

Here is a Zooz ZEN15 using the new DTH but old firmware (correct voltage):

Thanks for letting us know, we’ll look into it right away!

All I did was make a few changes to the configuration parameters, change some trace log lines to debug log lines, and increase the delay between some commands being sent to the device so it’s not possible that the new version of the DTH is causing any of these new issues.

The device requests a lot of reports when the device is joined so it can take 30+ seconds for all the tiles to populate. Sometimes some of the commands get dropped by ST so the tiles won’t get populated until the settings are saved.


(Warren) #270

Agreed but this was from an existing device. I simply saved the device settings and the “Firmware version” and voltage value updated a second or two after the save. But, I agree with everything else you’re saying and think it probably is a firmware change that is the cause here…and looks like they are investigating it.


(Warren) #271

@TheSmartestHouse, while you are at it, it might be me but it seems that with the 1.3 firmware I get like no or very little in the way of reports. Before, the devices were quite talkative. I need to take some logs for a longer time but it would seem that something isn’t being reported back to the hub that previously was. Thanks and appreciate the great support as always!!

Users were having issues with Smart Lighting because of duplicate events so I stopped forcing state change to true in the version I posted a couple of weeks ago.

Because of that change the recently tab will only show events that aren’t duplicate, but live logging should still show everything being reported by the device.


(Warren) #273

I think it must be something in the new firmware then. Using the new DTH, I have one ZEN15 that is reporting status normally as it used to with the old DTH. Also using the new DTH are several ZEN15 that have been upgraded to v1.3 which basically send next to nothing - even after a complete reset and repairing. Sounds like some QA is happening here.


(Warren) #274

One thing I will add is that old firmware or new, with the new DTH, I don’t see reports per the set intervals. For instance, if I set all of them to the minimum (like 5 seconds), I still get nothing much unless I hit refersh in the app. For instance, here is what I am seeing on a device with the old firmware:

Hitting refresh at 9:50 got me those two events at the top (and then the ST app updated) but in reality I should have been getting lots of stuff, no?


(Kevin) #275

Uncomment the log.trace line at the bottom of the code and see if that makes a difference.


(Warren) #276

Ok, so there is definitely a difference here but not sure what the deal is. Here are three different devices, all with the new DTH:

  1. Old firmware idle device (sump pump) with default reporting

  2. New firmware idle device (sump pump) with maximum reporting (every 5 sec, etc.)

  3. Old firmware device off and then on (should be 300W+ on) with default reporting

I have no idea what is going on since log 1 and 3 above are very different and log 2 is just odd IMO.


(Kevin) #277

If I had to guess, having the device send 4 reports every 5 seconds is most likely flooding your z-wave mesh causing ST to drop most of the reports.

To test that theory, change them all to 30 seconds and see if the reports become more reliable.

I’m getting something slightly different …

ZEN15 firmware 1.2.


(Warren) #279

Just wanted to check in to see if there were any updates or anything further on this?



We were able to replicate the issues when performing an OTA update from 1.2 to 1.3 and are still testing a new corrected file for 1.3 OTA. We hope to have it ready by the end of the week. We’ll post here as soon as it’s done.



We now have the new OTA file available for updates between 1.2 and 1.3 so just get in touch with us if you’d like to upgrade your 1.2 device:



I have noticed that interval reporting does not take place at zero watts. So it appears that my freezer completely turns off when it is not running. This leads to no reporting, and makes my energy plots look a little funny. Is there an easy fix for this?



You could disable power reporting based on threshold and use the frequency-based setting only, this way you’d get regular reports even if nothing is going on or if the value is 0.



@krlaframboise does this handler allow control over the USB outlets for turning on and off? Thought I had seen that somewhere but not sure if it was in this device or the power strip V2. Do not see any populated items either in the smartapp or webcore to acess those USB outlets at the moment.


(Kevin) #285

The Zooz Power Strip and Zooz Double Plug report activity on the USB ports, but they don’t allow you to control them. I’m unaware of any z-wave devices that allow you to control USB ports…
