Most of My Z-Wave Nodes Show Status Unknown

[cd-card-biz]

I have had my HS3 / ZNET setup working for a couple of years now.

Over the weekend, I began to notice problems controlling my 2GiG CT30 thermostat on Node 3.

I added it again and it registered as Node 12 and seemed to work fine.

Then, I deleted the previous thermo on Node 3. Probably the wrong thing to do.

Now, I am unable to connect to most of my Z-Wave nodes. A few still work and show status though.

When I test connectivity it fails and when I try to optimize, I receive: "The optimization was not executed as the node cannot be reached."

I would be really grateful if someone would give me some troubleshooting tips. I haven't messed with this stuff in years.

Thanks.

You might have a bad zwave device interfering with communications. I would reboot the house first. Kill the main breaker to reboot all switches etc. Reinstall all batteries in devices. Don't forget devices on battery backup. Then try communication again

Thanks very much for the reply!

I'll give it a try and post back.

I have a similar issue, which appeared after upgrading my Z-Net to firmware .23

Happily I did not have to throw the house breakers, which always seems to yield unexpected results.

I noticed that all of my offline Z-Wave devices were on one side of my thermostat.

I power cycled my thermo by removing the "C" wire and my devices became reachable again.

Did a full optimization and all is golden.

Thanks for the suggestion which put me on track to troubleshoot this.

My Z-Net firmware has not been updated. I don't even know what version it is.
