I just saw an alert that zwave is unresponsive and I just was curious if there was something that could have caused this.
When you say "alert" do you mean something in the logs? Can you post a screen capture? Are your zwave devices working despite the alert or are you seeing odd zwave behavior?
It was an actual alert. On the main page of the hub. None of my zwave things are responding from what I can tell. We actually 10 hours from home on vacation so I can't physically unplug the hub until Sunday night
Ah well that does make it slightly more challenging to diagnose. My first step would be to shut down the hub safely, remove power for 30 seconds (from the wall end to preserve that surface-mount USB connector on the HE side), and restart. Obviously that's more challenging to do remotely. I suppose you could just restart the hub and see if that helped.
I'm worried that my main box energy monitor and washer and dryer energy monitors are to blame. I've read that those can tax zwave a bit. However, I have had this set up this way for a while though with no problem.
I gave a regular restart a try. No luck. Will I do any negative effect if it stays this way till Sunday?
I can't see it doing any lasting harm unless some automation you depend upon stops working because the device is unavailable. Like your AC runs too long because your zwave thermostat is unresponsive... or your fridge chooses this weekend to leak and your zwave water leak sensor isn't able to report the event. Or your wave-controlled fish tank heater runs all weekend and you end up with a fish boil Sunday evening.

Do you know if Zwave is rebooted (same effect as power cut) when hub firmware is updated? I have an update available. It'd be great up I could do that and fix this problem too.
I do not believe so. I think the physical power down of the radio for 30 seconds clears cache and resets stuff within the radio itself. Of course it might fix the problem some other way... I mean at this point do you have anything to lose?
For future reference I have two hubs... hub 1 controls an outlet that hub 2 plugs into and vice-versa. If I ever have to reboot the hub I can do a safe shutdown and power cycle it remotely. However, that's kind of a dramatic solution for something I have to do extremely rarely.

That would be pretty easy to test. I've head that too about power monitoring outlets but I dont get the sense that three will overwhelm your mesh or cause the radio to stop working. How often do they report?
Have you tried turning the zwave radio off for a while and then back on? I don't think that actually cuts power to the radio but it is something you can do remotely.
Very interesting! So basically the set up is working on the extremely unlikely chance of both having an issue? Are they operating as clones of eachother?
Another solution I could use is to have a wifi controlled plug and use the native mobile app for the plug to cycle it after shut down.
Not clones. Both need to be running.
