Does Smartthings have the ability to set the protection parameters? Based on my conversations with Eric M in another thread, there 2 different Protection settings:
Local Protection State
Description
0
Unprotected - Device not protected, physical button presses work normally
1
Protection by Sequence - Internal relay disabled, but scene commands and config options still work
2
No operation possible - Physical buttons do nothing
RF Protection State
Description
0
Unprotected - device accepts and responds to RF commands
1
No RF control - runtime commands are ignored, but device still responds with status on requests
2
No RF response at all - Device will not even respond to status requests
If the Local protection state and RF protection state both somehow got set to 2 (via smartthings, a bug, user error, etc) it might look like the device is completely frozen. When the device appears locked up, are you able to change the Local/RF protection to 0, and if so, does that solve the problem?
I don’t use smartthings, so I not sure how you would change the setting (or if it is possible), but it might be worth a try.
I just had 4 switches completely freeze all at the same time in different locations throughout the house. Local or wave control didn’t work and needed an air gap reset to make them start working again. This has to be a ST issue. Although these are the same switches that always freeze. Any thoughts?
I’ve had one of two Red Series on/off switches freeze on me a couple times as well, since I got them about 3 weeks ago. I am using a Smartthings 1st Gen hub, and have probably 10 other z-wave devices connected up. The Red Series switches are literally a foot apart (on opposite sides of an exterior door), and the one that has frozen a couple times is the closer switch to all my other devices, so I’m thinking it’s not a distance issue. I’m thinking the first time the one switch froze, was after running a simple Smartthings Light & Switch SmartApp. However, both switches are part of that same routine, and the other switch worked as expected. The frozen switch recovered after my resetting of the breaker (both switches are also on the same breaker). I’ve also set them both up with scene control, if that helps the troubleshooting. I’ll play with them more than normal now, to see if I can get a better understanding of possible freeze conditions. Love the switches, can’t wait for the dimmers!! This will get figured out!!
Sorry, meant to include this in on my first post. The switch that froze, only has one LED bulb (9W) as a load. The second switch working normally has a T8 LED bulb-x4 (14W per) load.
Definitely an issue somewhere. I switched one of the problematic switches to hubitat so I can see you if it’s Smartthings. Seems like it shouldn’t be a range issue because I have had switches freeze that are sitting right next to inovelli switches that don’t.
I didn’t see the OP mention their device but basically same issues with NZW30 on/off which stopped working manually&wave after several months of loyal service. I haven’t flipped the breaker but I will when I get home. Air fuse did nothing, and my bathroom fan is stuck on (even with the air fuse out ).
Hey @Newlance - sorry to be short (on mobile) but the NZW series is our Gen1 and those are actually not rated at all for exhaust fans. They cannot handle an Inductive load like the Gen2’s (LZW series).
This is likely why you’re experiencing this issue
Edit: I see you mentioning the air-gap. Our Gen 1 On/Off switches didn’t have an air gap. Did you put a dimmer switch on the fan?

@biocomp Eric informs me this is not a true air gap – maybe just a dummy in the casing.
I have Home Assistant with a USB ZWave
Anyone figure out why these switches are freezing, mine still freezes everyonce and a while. I’ll jump in bed and tap my smartthings button to kill my light and nothing happens. I gotta get out of bed (first world problems lol) and try tapping the switch thinking the button failed and nothing and in the end I pull the air gap. Is their new firmware past 1.09?
This is happening to my red switches too. I have 8 installed. Three have frozen up in me. Nothing works from the switch manually and when z wave repair is activated it says, “Failed to update route.”
LED bulbs are installed, 5w dimmable. No other modifications are made and the ST hub is 3rd gen.
I’ve had this happen to a few of my newly installed red series dimmer and on/off switches already. They go from working fine both remotely and manually to won’t work at all and stuck either on or off.
Like many of the other people having issues, I use SmartThings hub (v3). From this thread, it looks like this problem has been isolated to SmartThings users.
@Eric_Inovelli Do you know if this is a problem with the device handler? Any working theories or solves? I always pull the air gap to fix it, but obviously that’s not a long term solution.
I wish I knew how widespread this problem is. I just ordered two switches that I wanted to test…as I am getting ready to home automate a new house. After reading the posts in this thread, I cancelled my order. A few years ago I became frustrated with Insteon switches that were failing at a higher rate than I wanted. I am impressed with the functionality listed for these switches, but I would like to get some reassurance from Inovelli as to the severity of the problem. I have the SmartThings Hub (version 3).
Add me to the list. LZW30-SN freezing on a Smartthings v2 hub.
I have the switch in a 3 way configuration with dumb switches. Sometimes it freezes with the lights on, sometimes off. Sometimes I can still control the lights with the dumb switches. I’m thinking this has to do with the position of the relay when the switch freezes.
I’ve tried a few different bulbs including all old fashioned incandescents.
I’ve also noticed that once in ahwile when I turn the lights on (from any switch) they flash on, then right back off requiring to hit another switch. This flash behavior doesn’t seem to correlate to the switch freezing up.
This is a known problem with smartthings and these switches. Not sure about dimmers cause I switched to hubitat beofre I installed dimmer. And glad I did. Hubitat kills smartthings.
Just installed the LZW30 on/off switch res series as a single pole switch using abode iota to control it. In less then 12hrs it has frozen 2 times. I like the switches and would order more if this problem is a quick fix.
From what I saw mentioned before, it seems so far the potential culprit might be secure (S2) pairing with controller. Habitat doesn’t do the secure pairing by default, and seems to be OK, and SmartThing does (and is not OK). I wonder if you could disable this (secure pairing) in abode iota (if it is the case at all) and see if it helps.
I’m also just following this thread trying to figure out if it’s worth buying more of these switches, if the reason is going to be found and fixed.
