@Darwin Just a quick update that I am no longer recommending my own smartapp for your excellent device handler. I have changed from using my own Button Controller Plus and instead I am highly recommending to now use @stephack Advanced Button Controller smartapp! Yes it really is that much better that I switched to ABC. 
[BETA] Advanced Button Controller (ABC)
It is faster to setup and so much more intuitive to use and it covers the latest firmware capabilities for button 7 & 8 control.
