Bought this "smart" meter from Apera solely for the app functionality. The app simply does not work, like at all. It will not let me sign in or create an account, the app instantly crashes when trying. I have tried everything in my power and have gotten nowhere. I even tried to see if I had an account my choosing the "forgot my password" option, and that insta-crashes as well. I have sent emails and placed phone calls and they told me they fixed the app, NOPE it is still totally broken.
