Home energy monitors need the ability to change the data displayed in the header. Right now, it shows total energy consumption with no space for instantaneous power usage. I would prefer it reversed, so this needs to be costumizable.
Also, Z-wave motion sensors that shows temperature still has the wrong units displayed. I want C but it only shows F in the app. The sensor shows C everywhere else (web, LCD).
The device type needs more types. Smart power switch, hue hub, and a generic gateway (Honeywell RedLink, MyQ, etc).
