If you're going to use the internal sensors to get useful outdoor 
measurements, yes.

Not the ones that are in there now.  The temperature sensor is part of 
the barometric pressure sensor, and it's a tiny SMT package.  The idea 
is that you'd use 1-wire sensors if you want external sensors.  Also, 
you'll be able to daisy chain two WS1's for indoor and outdoor measurement.

I'm still waiting on terminal blocks to finish up the first beta units. 
  I spent a good chunk of the day dealing with timekeeping code.  It'll 
now let you enter a GMT offset in fractional hours, so if you're in 
Kathmandu you can set your +5.75 timezone offset.

That part's easy - the tricky part is dealing with DST (Summer Time in 
some parts of the world.)  There are a zillion different sets of rules, 
and they change from time to time.  My solution was to store the offset 
in minutes and a schedule of the start and end date/times for the next 8 
years.  The configuration program will automatically set US DST, British 
Summer Time, and European Summer Time.  Beyond that, you've got to look 
up the times yourself.  And you've got to remember to run the config 
program at least once every 8 years to update it.
