One device in particular seems to almost always be in error. Once in a blue moon, I will get no errors. Every time there are errors however, the 1 particular device is always in error while all the other devices in error are sporadic and different each time. Other times, it will be only the 1 device in error by itself if there are no other devices in error.
I have replaced this particular device numerous times with the same outcome. The only thing that “helped” was to install a repeater outlet about 4 feet away from the device that always is in error. This was the only way to get this device to actually work continually. If I hadn’t installed that repeater outlet, it would only allow me to add the device and then it would be totally unresponsive.
So any ideas on what I could do? Everything is working perfectly now, but this issue always pops up again where it will become un-responsive and always is in error regardless of whether it is responsive or not.
Brand, model, and specific error message for the device which is always in error?
Most likely there’s some problem with that particular device and the other error messages are showing up when your other devices try to use it as a repeater. ( remembering that because it’s mesh, it may be different devices on different trips.) But there are other possibilities as well.
It could be location, it could be that it’s a bad device.
Speaking as a field tech, the first thing I would do is swap it out with one of the other switches of the same model which does work, Run a repair, and then see if the problems recur either with the original problematic switch or the new switch.
If the original switch is fine in the new location and the new switch flakes out, it’s the location. Then there are things that you can start looking at from there.
If the new switch is fine and the original switch continues to flake out in its new location, then the original switch is bad.
I did the exact same thing you describe and I’m confident it is the location. What is strange though is the GE receptacle repeater is only 4 feet away and doesn’t have the same issue. It is also Zwave Plus.
Anyway, The range extender is not necessary, it won’t do anything more than any other zwave plus Mains power device in the same location would do.
Anyway, any time it’s an inwall device, there can be something right inside the wall which is Suppressing the signal. It might even be the switchbox itself. Smartthings doesn’t really give us the tools to diagnose that. But it’s not uncommon for a light switch on one side of the room and an in wall receptacle on the other side of the room to have completely different broadcast patterns.
The next thing I would try is just a different brand of switch. They are all engineered a little differently, including antenna placement, and it might make a difference.
Jumping in here3 to add my two cents. The innovelli NZW30S switches i feel are crap. I have two of them that are 3 meters from the hub. over the past year, both of them stoped responding least 4 times. and again, 2 days ago. I can operate then manually but ST cant control them. My fix has been to factory reset them, and re pair them again. I regret buying them.
Later today, im going to swap one out with a wifi switch i have lying around.
I do have some of the cheep monoprice z wave switches around the house. They have never givin me any problems.I dont feel location is the issue. One switch is about a meter and a half away from the hub. No walls between. And the second switch is about 3 metes away with one drywall between. When the switches crap out, They usually do it at the same time. Very weird.
I suggest trying another brand of Zwave switch to be certain it is not the location. I have over 30 Inovelli Zwave switches and this 1 switch I. particular had always been an issue. I believe it is something weird going on with the location, despite being a few feet away from another Zwave repeater which is also a few feet from another and so on all the way back to the hub.
