dont suppose you have a guide to connecting the ook ask to the arduino?
I searched around but got a lot of unrelated topics when searching for arduino uno ask 
also, thanks a bunch, if i get this working you've potentially saved me a lot of stressing and having to find an alternative to my nice new glass dimmer switches.
I'm also going to pass on your findings to rfxcom and see if theres any chance of them getting the livolo switches working with the rfxtrx433
