“Leviton DZ15S-1BZ Decora Smart Switch with Z-Wave Plus Technology” using the Z-Wave Switch Generic DH.
Events for the switch showed:
7:50:02.722 PM ping command was sent to [device]
7:50:02.732 PM ping command was sent to [device]
7:51:04.693 PM Your SmartThings device [device] is now offline
7:55:56.670 PM Amazon Alexa sent on command to [device]
7:55:56:675 PM on command was sent to [device]
7:55:57.052 PM Your SmartThings device [device] is now online
The Leviton showed as online and switched off in the new ST app so I tapped the tile to turn it on. The light turned on but the tile did not update to reflect that. So I can’t turn it off via the app. Alexa, however, happily turned it off.
I got the same behavior with the cover plate off. So I guess that isn’t the problem.
In Live Logging, I see “debug Parse returned switch button was pressed” if I tap either the on or off paddle on the Leviton. I do not see that same debug message when I tap the paddles on a Zooz ZEN26 switch I have which is using the same DH.
I see that same debug message in Live Logging if Alexa sends a command to the switch.
I’ve got a routines to turn the Leviton and a Zooz dimmer which controls some other lights in the kitchen both on and off. I have a virtual switch to control both together by running the routines. Using the virtual switch and the routines works perfectly, just like Alexa.
The only thing not working is the tile/button for the Leviton switch in the apps never gets updated to show the Leviton as “on”. And, if the hub sends a ping, it must not be responding because it then gets marked as offline.
It’s switching in response to a basicSet, but won’t send a report in response to a switchBinaryGet. It being marked offline is because it isn’t responding to the ping, which sends a switchBinaryGet. Meanwhile, it shows online when you use Alexa because it sends that switch was pressed event (which appears to be the Hail command class).
Exclude/include is a good step to try. You might’ve already seen the thread below, but it’s a success story that might work for you. Otherwise, could try to see if it responds to a basicGet.
Ouch. There’s always a chance that this could be solved in the DH, depending on what the device does/doesn’t respond to. There are a few different zwave commands that could potentially get it to report state, and maybe it’ll respond to one of the others. Is the dimmer using the “Z-Wave Dimmer Switch Generic” DH?
From what I’m reading on the thread which suggests updating firmware, it’s some sort of sync problem.
I’m using the “Z-Wave Dimmer Switch Generic”. There is a community-written DTH but it seems to not fix this problem. Folks who have gone thru the hassle of a firmware flash seem all end up with working switches.
My two DZ15S switches seem to be fine now. One of them has been perfect from day 1 (leading me to order a couple more Leviton devices), the other one caused me to initiate this thread. Both are now in a double-gang box in the garage.
The dimmer is now in the kitchen behind the metal cover plate.
