Hi all
If I may chime in here.... I am the manufacturer of something similar to the Stickstation. My product, called MBox, delivers Temperature, Pressure, Humidity and Dewpoint and has an ASCOM Driver too, so it's compatible with all astro software that supports ASCOM Version 6.2 or newer.
There's also a version available that includes GPS information, to have a "all in one" device.
You can find more information here:

P.S: I hope I am allowed to make this sort of post...
