I’ve had a working Z-Wave setup for five years: Linear WT500Z 3-way switches, several with associated WD500Z dimmers. When I first set things up, I used an Aeon minimote to associate each dimmer with its master switch. Later, I added a SmartThings v1 hub.
Everything’s mostly been working fine. I had an “all downstairs lights off” automation that stopped working somewhere along the line. The SmartThings app changed a few times. Nothing that important broke, so I just left it all as-is.
About a month ago, almost all of my remote dimmer switches just stopped working. I can still turn on/off lights from the masters, but the dimmers don’t do anything. Only one pair continues to work.
Attempting to re-pair with an Aeon minimote isn’t working, and enough things seemed to have changed in the SmartThings ecosystem that I’m not sure if what I’m trying to do is even possible any more. I could use some advice, since searching turned up lots of articles from 2013-2015 but nothing worked & I don’t know if they’re are still relevant.
All switches are powered. The minimote -seems- to be working. Exclusion/inclusion causes blue/red lights to flash as expected. An excluded master switch still turns on/off the lights, and though the switch remains visible in the SmartThings app, I can no longer use the app to control the switch.
Association via the minimote begins, but can’t complete: press Associate (blue light blinks slowly), double-tap the dimmer switch (blue light blinks faster), double-tap the master switch … nothing changes. I’ve tried excluding and re-including both the dimmer and master, still no association.
Note that I’m trying to do a z-wave association, not ST automation aka “follow”. I read a few threads that said this was no longer supported, etc. but I can’t see why it shouldn’t be since I still have the same hub and minimote that I originally used to set the system up.
- Are the dimmer switches supposed to be discoverable and show up as their own ST device? (they don’t)
- Are changes I make with the minimote supposed to be reflected in the ST app? (they’re not)
- Is there some chance that the ST hub is interfering with the process? I don’t know that much about how z-wave actually communicates with/without a hub.
- Is there any kind of diagnostic utility I can use to investigate my system, beyond the two SmartThings apps?
Thanks for any advice!
