After adding a Atetec Home Energy Meter to the gateway, I have had nothing but problems. When I finally got it set up right, thanks to customer service, the unit worked flawlessly for about two weeks. One day it recorded a negative 64Kw consumption and the next day it had a 60Kw spike in usage. Of course this threw off the daily totals. Concerned that this would continue to happen, I flashed the zwave and reinstalled the HEM again. It seems to be working, but when I check the Chilicon website, it is not getting any consumption information.
