Any change of adding Deep Sleep capabilities?

I'm interested in the ability to run Konnected on a battery for instances where there is no accessible power source  (one example could be monitoring the temperature and door closed status inside a refrigerator.  I have seen that NodeMCU supports deep sleep mode, and I was wondering if you would incorporate that into the firmware.

It would be kind of cool to allow the user to choose the update interval and have the device sleep for that amount of time.

the wiring is super simple.
