Set up a ZooZ Zen15 z-wave device to monitor my sump pumps.  A little while ago a got a message that one of the pumps had consumed 9+ kWh in the previous 5 minute period.  Logged in console and examined the device in question and it was still reporting 0.094 kWh like the last time I looked.  The variable that I track changes with was set to 9.4 kWh. It gets set directly in only one line of code and only if there is an increase.

So I decided to look at the logs.  Mostly it get sets correctly, however there is a lot of random crap including one instance of 107 GWh! Oddly it didn't trip my monitoring program which would record any increase. Somehow there is a disconnect between the program and the log as well as the device. Any suggestions on debug?

Update:  I have the same device on a second sump pump. It's log it littered with the same random data.  However, none of it has caused the monitoring program to be tripped.  What are the odds of 2 devices failing at the same time? Or is the problem more likely somewhere else?
