This is so frustrating.

Again I have disappearing Zwave devices. Still have to check how many I've lost. Right now I've noticed two of my receptacles disappeared.

I haven't used them for long time. They were installed only to initially help with Zwave mesh but I have not used them for anything.

I can manually turn them off-on with local button but nothing shows in "Event viewer". "Exclude", "include" doesn't do anything. They must be too far from ISY. Pain in the b... to remove the outlets and bring them close to ISY.

ISY v.5.3.4

Zwave board 500.

Anybody have any idea why it happened?

The ISY Zwave antenna is inside the enclosure, so its range is somewhat limited. You need to have either a repeater or a non-battery Zwave device within about 15 feet from the ISY to relay the Zwave signals.

You can also try the "Synchronize nodes" option in the ISY Zwave menu

I have to double check I think outlets are 300 series --so no "Network Wide Inclusion". Have to have them close to ISY.

I have like 30  powered zwave devices in 1000sq.ft house so don't think I need to add any repeaters

P.S ISY is mounted on the hallway wall 5ft high in the centre of the house.

Is it possible that after I have not used the outlets for long time ISY marked them as failed and at some point I told ISY to "Remove failed node"?

@tibbar

Try the "Synchronize nodes" option in the ISY Zwave menu.

Based on your hardware you should have a viable Zwave system

Tried "Synchronise" , didn't help. On one outlet tried "exclude"- nothing, tried "Include" few times and it came back with old Zwave number (came back as ZW004). Second one excluded successfully and included as ZW090.

It's possible that you have a defective Zwave device

Every time you exclude then include a device the ZW number will increase by one.

I understand that. That is way I have 30 devices and number ZW090. All the excluding and including of the same devices throughout the years.

What is your ISY UI version?

Your devices shouldn't be disappearing from the ISY. Have you tried removing power from the ISY for a cold boot.

UI is the same as firmware v.5.3.4

I've had the ISY for 9 years so yes I had one or two power failures  plus numerous cold reboots.

Being that your problem is intermittent, the only other suggestion is the SD card. Remove power from the ISY, remove the SD card and clean its contacts with a soft eraser.

If you still have problems after that then replacing the SD card might help.
