I'm a WD user at the moment, but I'm more and more interested in Meteohub, due a lot of problems with the Mac version lately

Is't somehow possible to import my weather data to Meteohub, or set rain manual, and possible set lowest and highest temp recorded?
I'm also a WDL user - is there any issues with WDL and Meteohub?
What hardware are recommended for a new user - Sheevaplug?
Thank you
