Battery Level of ZWave Devices

Is there a way to report the battery level of the various zwave devices?

VeraPlus, SmartThings, and Nexia all did so but I have not seen that in HA. I did not see anything in OZWCP that stood out to me so I assume there is some kind of polling going on that gets a report on the battery level.

Look at this and see if it helps you; This is what I ended up using and am happy with it.

That looks about perfect! Just one question the custom_components/battery_state.py, does that go in /home/hass/.homeassistant or in the /home/hass/deps folder?

Thanks for the link @Corey_Johnson

Make a folder for: /home/hass/.homeassistant/custom_components and then save battery_state.py in it.

Thank you, sir, very much appreciated.
