Zooz Zen17 relay

Seeing supervisionCheck errors with uncommanded relay state changes on ZEN17 too. C7 hub running latest software. ZEN17 on 1.04 firmware.

Have experienced same with Aeotec Smart Switch 7 devices as well. Using a generic driver and S2 security seems to fix as does using default driver with security "none". I don't find either of these solutions satisfactory given C7 claims S2 support and SS7 is explicitly listed as a supported device.

Confirmed- same everything except I re-joined the ZEN17 with no security and the functions are normal & predictable, including DC motor mode (one relay never steps on the other).

Mine's joined with no security and has been working as desired on 1.04 for a couple months now... Since it controls my garage, I'd like to get it on S2 someday, but no way I'm doing that anytime soon - S2 is just way too wonky overall right now!

This is resolved in 2.2.8 that is currently in beta

OK. Waiting patiently and hoping it's really resolved.

Wiring question with the Zen17.

So currently I have it powered with a 5v 1amp power adapter using USBC. Then i have a toggle switch attached to Relay 1 input terminals, and the fireplace power connection to No an C for Relay 1. This is working fine except for the occasional issue mentioned above. Last few times i tried it, it seems to be fine.

The next thing I am wondering about is hooking up some fans to the Zen17 that are powered from 12v. My question unlike what i did on relay 1 where i didn't need to supply power to any device, How would i wire in power and use relay 2 to supply the power to the fans. The documentation throws a bunch of red flags about not using multiple power sources.

The multiple power source red flags are related to powering the Zen17 device itself. USB C port or the wiring power port but not both at once.

You can simply wire the 12v + side of your power to the 2nd relay's C post and the fan's side of the 12v + to the NO post to control your fan. Like any other normal relay implementation.

Hi all,

My Fortrezz MIMO2+ died and I was replacing it with a Zen17. On the MIMO there's a setting for a momentary on/off on the device. However on the Zen I can't find one on the parent or component. My desired use is just for a button on the dashboard to close a dry contact, nothing crazy.

I'm sure I can write a rule but it seemed like perhaps I was missing something obvious...

Is there a better way to be doing this?

Thanks in advance for the help!

Parameters 6/8 and 15/17 enable you to set an auto-off for the relays so that the relay actuation mimics momentary on/off behavior. Unfortunately, these parameters aren't currently exposed using the default driver.

You can use the "Basic z-wave tool" driver to access those (and other) parameters though, and it works well. I did that for my relay so that it mimics the garage door opener button.

Hopefully at some point they will add these as exposed parameters. Bryan seemed to imply that he would work on it when I asked this same question recently at about post 135 or so. :arrow_up:

But for now, the Basic Zwave Tool works OK to set these parameters as @hydro311 listed. Super basic Z-Wave parameter tool

Ah yes parameters, thank you! Completely forgot to think about that.

I've gone ahead and set them to what should turn off after 1 second of being on, but I'm not getting the expected behavior. The relays just turn on, NOT on then off after 1 second.

Am I missing something obvious? Thanks again!

Huh, those parameters look correctly set up to me, so I'm not sure... Are any other rules that previously controlled on/off behavior disabled for certain (to ensure nothing is "clashing")?

I use a 2-second delay for my auto-off, but 1" should be no problem too.

Brand new device, so no rules yet. I went as far as to delete and re-add just to make sure.

I had tried 2 seconds as well and had the same thing.

Hmm...

Are you on firmware 1.04 for the Z17?

Looks like I'm on 1.03, guess I'll give the new fw a try. Thanks @hydro311 !

Make sure you join without security before you try the firmware upgrade. I had a heck of a time teying to upgrade it with S2.

I just received a Zen17.

  1. Is there a reason why the "10 - Dry Contact" selection does not create child devices that can register as on/off sensors? I don't see any way to use the 2 "dry contacts" as designed.

  2. What is the latest firmware I should have and where can I get it if it's > 1.03?

Maybe @agnes.zooz or @bcopeland can chime in.

Thanks.

Not sure about #1 since I'm using "7" for my magentic reed contact sensors.

For #2, 1.04 is latest firmware - email them here and ask for 1.04... They are usually quick to respond and will send a compatible update file.

Recommend doing to f/w update with the Z17 paired as no security - doing it w/ S2 has caused issues for some (mine updated fine with no security). If you want to use S2, I'd do that after the f/w update.

I have the parent Zen17 set as follows:

That created 2 contact sensors.

I have 1 hooked up to a relay that closes when my furnace fan is running.
I have 2 hooked up to a relay that closes when my house smoke alarms go off
I have relay 1 hooked up to apply power to turn ON my house smoke alarms when closed.
Relay 2 is unused

Sensors 1 & 2 are hooked up to the S and neighboring C contacts.

When the furnace fan was running, I measured 0 ohms between S&C for #1. With the smoke alarms NOT activated, I measured very high resistance between S&C for #2.

However, the Sensor 1 & 2 BOTH showed "closed".

I am totally dumbfounded, though, because (after a bit) the sensor 2 child device started aligning with the fan (Open=Off, Closed=On)--even though it was connected to S1.

And, NOTHING seems to make the other sensor device trigger.

So--I pulled the power on the Zen17 and plugged it back in.

Poof--started working as expected. Odd.

I ended up calling the sensors "Contact Sensors" even though I'd have preferred to call them "Switches" so they'd use "on/off" instead of "closed/open"--but things work (and it is really hard to change those now!).
