Best way to incorporate my Somfy glydea motor to Zwave

Hello, hope some one can help me here with some piece of advice; I’ve a somfy glydea motor that I want to incorporate to my zwave network at home, doing some research I found that the Somfy ZRTSI RTS 16 can control that kind of motor, however I think it’s overpriced to controll only one windows cover, any other ideas???

this is the zwave somfy motor controller that I talk about: [url=http://www.amazon.com/Somfy-Channel-Z-Wave-Interface-Module/dp/B00HSOMH0M/ref=sr_1_1?ie=UTF8&qid=1461610734&sr=8-1&keywords=Somfy+ZRTSI+RTS+16]http://www.amazon.com/Somfy-Channel-Z-Wave-Interface-Module/dp/B00HSOMH0M/ref=sr_1_1?ie=UTF8&qid=1461610734&sr=8-1&keywords=Somfy+ZRTSI+RTS+16[/url]

thanks a lot.
