This makes me think that there are portions of the MySensors library that take advantage of the lower power modes available, like STANDBY-I and PowerDown. That's all great, but it begs that question;

"How exactly is the MySensors library adjusting the power modes of the ATmel chips (which modes when), and does this same power-awareness apply to, say, the radio boards (nRF24, etc.)?"

Right now, I have my first true battery-powered node drawing 7.1ma in [whatever mode(s) MySensors library is putting everything in]. Is this as good as it gets (I pulled the PWR LED), or are there further options available using, say, interrupts as an example, that could bring power consumption down further?

Thanks!
