I just updated my Zen51 with f/w 1.80 – all of that went very smoothly on my Hubitat.
Everything seems to be working great except that my Z51’s LED no longer comes on with the relay.
I have triple-checked my parameter #1 setup (it’s set at 1), and even tried cycling that parameter from 1 → 0 and back again in hopes that would shake it loose, but no joy.
I suppose it’s possible that my Z51’s LED died, but it was working last night (when I happened to be doing some unrelated checks that involved monitoring that Z51’s activity).
Curious if this is something you can reproduce on 1.80? Thanks very much!
Would you be able to confirm the production firmware on the ZEN51? This is printed on the back of the device; since we haven’t had any other reports, we’d like to check the original firmware to be sure we are testing accurately.
Can you also please let us know what firmware you were on when you updated to 1.80?
Thanks Sara! This is a Z51 that I’ve had in service for years now (I bought it when they were first released, IIRC). It’s been a great performer – I’ve keep up with all the iterative firmware updates, so I made this jump to 1.80 from 1.70.
The relay itself works great on 1.80, I just found it odd that the LED no longer comes on when Param 1 = 1. This is very admittedly a 1st-world “problem” - that LED working is not any kind of showstopper for me. I was more just curious if that is something you folks (or any other fellow users) are able to reproduce it on 1.80.
As I mentioned in my OP, I happened to be utilizing that Z51 as participanting device in a new automation build last night (though no parameter changes to the Z51 itself), so I was watching its operation – the LED was working fine on 1.70 last night (on with relay on, off with relay off).
Had I not just verified its operation last night, I would not be nearly as confident that this LED issue has something to do with 1.80, but the timing seems otherwise too coincidental.
Thanks again very for your time and help!
Edit to add – other than trying to cycle Param 1 (it’s now confirmed =1 again), I didn’t make any parameter changes when I updated to 1.80, and I’m using Jeff Page’s latest Hubitat driver for the Z51 (which is what I’ve always used for this relay).
Thank you for those details!
Our technicians have pinpointed an issue with the original production run (base firmware 1.10) being updated to 1.80. They’re working on a quick update that should fix this. We’ll reach out once the fix is ready, which should be shortly!
I wanted to reach out with an update. After working with our engineers, they have confirmed that they will not be able to implement a firmware equivalent for 1.80 that would apply to the 1.10 base units. This is due to the hardware change that was made on the unit with 1.30. We do have some warranty options available for you, so please reach out to our team directly and we’ll get it taken care of for you!
Thanks for the update and the kind offer. Until all this happened, I hadn’t ever realized there was a hardware version update at some point after the Z51’s original launch.
Honestly, outside of the LED issue, mine’s working perfectly fine on 1.80, so unless there’s some other reason I should either downgrade (I could - I still have the older f/w file) or pursue a warranty case, I’m totally cool with how things are. The LED thing is not a big deal for my use case.
You guys did me an above-&-beyond solid a while back by replacing a Z36 battery pack that was out of waranty, so I don’t want to take any unnecessary advantage of your good-faith support offers - I can live with my Z51 as-is.
FYI - there seems to be an issue with the Z51’s v1.80 ZIP file that’s posted on your OTA page…
When unzipped, it opens a file named "ZEN51_V01R80..gbl " – note the 2 periods in the name.
Strangely, I’m not able to edit the file name in order to remove one of those periods.
I didn’t notice if this happened when I tried the 1.80 f/w update earlier – I mistakenly permanently deleted my copy of that file, so I was just making another one for my records here when I noticed the 2-period issue.
I did end up replacing my original-model Zen51 with the latest version (received today from TheSmartestHouse)… I just loaded v1.80 firmware, and LED issue I described in my first post still applies with the new-model hardware too.
I have the LED set to come on with the relay, and it’s not (the relay switch works great, so no problem there – just the LED). The LED works fine on 1.70, so it’s an issue with 1.80
Apologies if you already knew this, but this thread otherwise seemed to imply the issue was perhaps unique to the original-model Z51.
Hi Chris, thanks for those details! We have not had anyone else report the LED behavior, so that’s a new one! I’ll have our team check it out when we are back in office next week (currently as the ISC-West Trade show in Vegas). I’ll update you as soon as we have more info; we appreciate your feedback and assistance!
My pleasure, Chris!
Our remaining techs in office were able to replicate the same issue, and it appears to only occur when the device is added to the hub, which is why no one else has reported it yet :). We should have beta firmware available here in the next few days, so I’ll reach out with a link to that and it should resolve the LED issue for you.
Hi Chris! I had an update from our techs and we have a beta firmware available if you’d like to try it. Since it’s beta, please reach out to our support team directly and we’ll send you the file
