battery check and System.sleep

[helmarw]

i can only tell for Argon since Xenon is deprecated

Battery check doesnt work:
if(BATT > 1) gives always 33, no matter if LiPo or USB power is supplied
i could not find any way to check if battery or USB is connected, yet

System.sleep(D1,RISING,12h) alone does not help, its still draws about 60-80mA
thats because wifi-module does not get disabled.
so change the code to:
WiFi.off();
delay(250);
System.sleep(D1,RISING,8h);

(and yes 12h is correct, since fw 1.5.0 you can use the usual chrono literals)

further more you might want to explore the new sleep API:

havnt got around doing it myself since the classical API is still working,
and for Argon/Xenon i thing it might not really be helpful or increase battery life, but
i havnt tried it yet

but really nice work, i enjoyed making them. i made three so far and a cover
to slide over to protect it form the elements, a bit at least ...
