I have a Zooz Z-Wave Plus Power Switch ZEN15 that has a small condensate pump attached to it, and also another ZEN15 with a dehumidifier on it, both in my crawlspace. I have those setup with the same type of routine to notify me when the wattage increases to let me know each is running. Now the condensate pump only runs for about 10-20 seconds, and the ZEN15 reports immediately as is should. The dehumidifier can run for many hours, but those have worked great for close to a year as far as reporting. When the well pump runs it probably runs for 3 minutes or so each time to fill the pressure tank. And it did “seem” to work correctly at the beginning, sometime last year. I had noticed every now and then that I didn’t see a notification recently. I tried cycling the power by shutting off the main breaker to it. That seemed to work most times. Now, nothing seems to get the reports to be consistent.
Anyway, I am in the process of reading through the custom DTH for the ZEN15 to see if there is anything there I can see as to why it works so great and reports as the event occurs. I want to compare that custom DTH to the built in one for a zwave smart metering switch. Maybe there is something to be tweaked? or maybe my device is just defective?
