I have been installing a bunch of LZW30 around the house over the last few days and as a result, need to constantly cut power from the panel to different areas of the house. I have paired them to a C7 with S2 authentication. I have already set them up in the motion lighting app on a couple of them and they have been working just fine over the last few days. I noticed that after I cycle power to those switches from the panel, the automations stop working. I am having to execute the configure command to get things working again. I also refreshed the child apps for sanity sake. Is this behavior normal?
When you kill the mains power on a zwave device you will also break any routing through that
device until they find a new route around the 'dead' device. IF there is a new route, There's no easy way to know that information. So, yes 'unrelated' automatons could break, for a while. You should run a z-wave repair after each switch installation. That will help the zwave devices find each other. I have LZW30's and everything is running fine for me.
This seems surprising to me. I read "power cycling" as cutting the power off, then restoring it immediately. It would make sense that a repair might be needed if a device was just left powered off, but if it has just been power cycled, I'd expect the original routes to still work. I always assumed z-wave devices retain their routing information across a power outage. Not like I know for sure - z-wave still shows unexpected behavior for me enough of the time!
Z-Wave repair is used after installation/removal of devices. Not for power loss or cycling - unless that's part of installation. It's not a solve everything procedure. If your z-wave network is working fine then a repair is harmless to try. If it's not working well, then a repair may help. Open the log in a new browser tab and watch the messages during the repair. It can take many minutes to run, depending on your network.
