My watchdog pump crapped out so building my own backup. I will be using zen17 relay switch. I can't figure out how to make it run for set time like 8sec when activate by contact switch.
Anyone able to provide some guidance? in simple rules there is a delay but for HH:MM no seconds.
Edit: sorry, I re-read your post. You'll need to use Rule Machine, not Simple Automation for this one to get it dialed into seconds.
Unfortunately, the device can't accept a "pulse duration" command. Here's what I have set up for my coffee pot filler valve:
I put the "wait for on" in there to try to get the timer to be as accurate as possible in case there was a delay in the switch turning on. The trigger in my case is a button, not a contact, but would work the same. Also, mine is on a ZEN 16, but again, shouldn't matter.

The relay can be set via parameters to natively do timed auto on and auto off.
You can change the parameters by temporarily using the Basic Z-Wave Driver.
Manual is here:
edit: I think you can adjust the input on the Zen17 to momentary, though I haven't tried that.

I completely forgot about that and it could definitely work for @user5032. It couldn't work for me because I have buttons for 1/3, 2/3, and full pots of coffee.
I do have that parameter configured for 41 seconds though as yet another "overfill safety" since my coffee pot takes 40.5 seconds to fill.

I'd have water all over the place if I tried that automation!
Where are the parameters controlled, when I look in device settings it I dont see an option to tweak parameters?
Believe me, it still makes me a tad nervous. I have as much safety built into it as I can think of including a leak sensor that sits right beside the coffee pot on the counter that has a rule that completely shuts everything down. The private Boolean you see in my 'if' is to make it so the buttons lock out after being used once in a day etc.
That said, I'm positive that someday I'm going to wake up to a mess, but for now, I really like the system!

See my post above.
Unfortunately, the stock driver for the ZEN17 doesn't have those parameters built in. The Driver for the ZEN16 does and it appears that they are the same parameter numbers, so you may want to try switching to that driver to make it a bit easier. Definitely test after you switch back to the ZEN17 driver to make sure it took.
This is the ZEN16 driver:
and this is what it looks like:
EDIT for Posterity: I did not know that @jtp10181 had created the companion driver for the ZEN 17 - don't do what I summarize below - use his companion driver.
Just to summarize what I would do:
Select Zooz MultiRelay Driver -> Save Device
select '8' for parameter Auto Turn-off Timer for Relay X [either 1 or 2 - whatever you're hooked into, don't touch 3]
select 'seconds' for parameter Auto Turn-off Timer Units for Relay X
Save Preferences
Hit Configure and Refresh at the top
Go back down and switch back to the Zooz Zen 17 Driver -> Save Device
Test to make sure it is working as you intended.
THanks. I ended up finding code for the zen17 so now see parameters. is the number I enter hours, min, sec? It doesn't let me enter in HH:MM:SS format just a value but not sure what value is.
The number you enter is driven by parameter 15 (for relay 1) or 17 (for relay 2)
From @velvetfoot's link:
So for relay 1, you'd want to set parameter 6 to '8' and parameter 15 to '1'
Use this companion driver to access all the ZEN17 settings. I would avoid doing it on the ZEN16 driver, the parameter numbers may not all line up exactly and cause problems.

Yes, that's even better advice yet.
I"m looking at Parameter 6 - it asks for value 1-65535
Is 8 not between 1 and 65535?
In all honesty, if you take @jtp10181's advice, you'll have this done in about 2 minutes.
Ok sorry I misread I understand now. I changed para to sec and changed to 7. I triggered it on but turns off instantly not delay.
I'll try but seemed a little over my head.
I just tested setting it with companion driver and it stayed on for 7 seconds. Switch driver, first Sync from Device, refresh, then change setting, then switch back to normal driver to test.
Man, I feel like I do some risky stuff sometimes, but this one's outside even my comfort zone...
good luck!
