Possible to manually power off/on Nova in software?


I’m working on a project in which reducing power consumption is pretty critical (raspberry pi zero, with some sensors and motors, and Nova running off battery and solar panel). When the Nova isn’t plugged in, I cut about 50mA. Is it possible to power off/on the Nova from the Python SKD? Or by some other means? Or perhaps a deep sleep mode? We only need to send a message once an hour so if we could get the Nova to be off in between that would be very helpful.

Thanks in advance!
