I just thought I need to drop a big thank you to all contributers, I am loving HA so much, thank you very much 
Newest example: Bought some Velux window covers, checked the HA Integration page for that, then ordered the mentioned KLF200, and minutes ago I started the HA configuraiton as described (super easy) and within no time I now have working automations for closing / opening / stopping all of them 
Normally you write mostly when having problems, so I thought after such a flawless new use-case for me I needed to drop that 
Such a great software
