Starting with BroadLink Experience

hi,

I’m planning to Buy ans BroadLink Pro to control Air conditioning and roller shutters.

I’ve two questions that I appreciate who can answer and and help on having this fantastic internet of thing.

1- For roller shutters I’ve electric shutters installed with manual switches on wall (2 buttons switch)

2 - For air conditioning, I’ve to exact models on the living room! Maybe when i turn on and control then it will be in parallel, correct? What if i what just to connect and control just one (being more energy efficient)

thanks in advance,
Helder
