I am having a ton of issues with my Z-wave devices and I am trying to narrow down the cause. It could be a faulty GE Z-Wave Smart Switch, it could be that my hub has a bad Z-wave radio, or it could be a connectivity issue with Z-Wave in my house/neighborhood.
To preface before I dive into the issues here are a few points for considerations.
This is my second hub. I bought a Samsung SmartThings Home Monitoring Kit before going on a vacation (as there weren’t any hubs available in my local area in the timeline i needed). So once i got back from vacation i returned that and bought a hub by it self as this suited my needs better then the kit. I don’t know if the Z-wave issues existed or not on the first hub.
The zigbee devices in my house work great. I have two samsung smart things multi purpose sensors. The closest one is a few feet away from my furthest Z-Wave switch. The second one is another 20-30 feet away from those two devices and is the furthest device from my hub and it works great and reports status instantly.
I have removed my Z-wave devices and re-included them, I have restarted my hub, I have repaired my z-wave network via the IDE (and it always fails every attempt).
So here are my Z-Wave devices:
- GE Z-wave Dimmer Switch
- GE Z-wave Smart Switch
- Utilitech Z-wave Siren
- Utilitech Glass Break Sensor
and here is my situation that leads me to be unsure of the problem is the hub, a specific switch or my local environment.
I have the dimmer in my bedroom (approximate 10-15 ft from the hub). I then have the smart switch at the bottom of my stairs (maybe 30-45 ft from my hub and 30 ft from the dimmer) The switch is to control outside porch lights and i bought it with the purpose of having it turn on and off the porch lights and sunset/sunrise. This switch is the one that is next to the closer multi purpose sensor. This switch is easy to exclude and easy to add (no problems and done it multiple times) and if i set up a smart app to turn them on at sunset that usually works and that command usually gets through fine.
It is once that command is sent that everything starts to go haywire. Basically once that command is sent all my Z-wave devices lock up and all control is lost over my z-wave devices. Once that command is sent i can no longer control my dimmer in my bedroom and when the off command is sent in the morning it sends but the lights do not turn off. The app also does this weird thing where the “Things” page will show the right status - lets say on, and then i will turn it off - nothing happens but the “Things” pages show off. If I click on the device to view (lets call it the device detail page) the device will still show on. So basically i have no control and conflicting device status reports.
The only things that seems to fix it is enough time passing to where it starts working again, never really sure when this will occur, so devices just don’t work until the magically do again. Or if i restart the hub this seems to fix it.
While all this is going on (Z-Wave not responding) my zigbee devices still work perfectly.
At the same time as all of this (both when the Z-wave devices are working and not working) I have tried with no success to get the ultilitech z-wave sire to pair correctly. It pairs all the time but just not correctly, i only have off options and there is no device status found in the IDE, which i was told means it did not pair correctly. i have excluded and re-paired about 15-20 times now and always the same result.
So i am not sure where the issue is and what is causing this. I also know that i can buy zigbee switches and dimmers to replace the z-wave ones, and I’m not against that, but I intentionally bought the z-wave ones since a majority of the compatible devices are Z-wave and i figured it made more sense to have Z-wave repeaters then zigbee repeaters since most of the non samsung smartthigns devices I add will be Z-wave.
Now I’m debating if Z-wave is viable at all in my house. If it’s not this will greatly limit what I can do with smartthings as most things will not be available to me, if i cannot get Z-wave working consistently in my house…
As far as the glass break sensor, i got that to pair correctly as far as I know, but I have no actual idea if its working or not lol, but it at least has a status found in the IDE unlike the Siren.
I would appreciate any help, feedback and ideas from this great community.
