Our Oregon Scientific home weather station has these nifty little programmable alarms for certain weather situations. Gee, why wake up every 3 hours to feed the fire when you can just set an alarm to go off when the temp in the tent gets below 50F?!
Lat night, I got my first mostly full night of sleep since the weather turned cold... and it was still nice and toasty enough that I wasn't doing the chatter-dance waiting for the stove to heat up. Inspiration I tell ya!
