Two other considerations:

Power supply: give some thought to a solar system to power the Pi. If it is as 
remote as it sounds, it sounds as if outages might easily occur? A solar system 
might even power the Davis unit; I don’t know the Envoy but if it uses alkaline 
batteries I am not sure of their tolerance for prolonged cold.

Wi-fi: not sure if you’re using wi-fi to connect any of the devices but if so, 
set the wi-fi router to a fixed channel, in addition to doing the IP address 
reservation. The fixed channel trick can make it easier for wi-fi 
<http://wi.fi/> systems to connect again after power stutters.
