Saw the Kickstarter update, and it occurs to me that this is the first external sensor with more than just 1/0 values.
Does this mean we may see other sensors with ranges of values, such as "how moist"?
Also, can we have a rule that compares the internal and external temp values? e.g.
IF temp.internal > temp.external+20 then
EMAIL "Wear a sweater, stupid!"
