I deployed 5 sensebender nodes just after release in 2015, all with 2 AA batteries from ikea.1 died within a couple of years, because it was placed outdoors. But the rest kept going, and all have been going until this year. So 8 years of battery time on one set of batteries..
I think that is excellent battery life..
bravo and good explanation
good to show that Arduino "8bits" and MySensors can do things simply, without gas factory
an extensible basis for further input/output
(door contact - relay control ...etc )
Thanks

RTC is the same as compile time! (not expected but all is fine)
