A W E S O M E - SWEET!!! Way to go Ranga!! 
If you can’t wait for the retail version I posted how to contact the fan manufacturer to order repair parts months ago but they still were delayed in getting it out, glad they fiinally started shipping. The $72 kind of cooled my jets after seeing the much lower retail pricing. I was debating about getting it but now that I know it’s ZHA I placed the order.
Calling out to Scott @Sticks18 for a little direction. He will look up to see what the public cluster is and your next step. I think he will want you to click on each of the buttons and capture the code that it is sending or something like that.
Here is my suggestion though… Go grab the code from this great device handler for the GE Smart Fan Controller by @ChadCK which started out from @johnconstantelo super foundation of code. This device handler works extremely well and the user interface is awesome. You don’t need to reinvent the wheel in this area and I am sure the guys will help. You could add the light and timer controller functions
(@JDRoberts can you move Ranga post above over to the right forum) Or before we get too far, If you don’t mind I need @ranga to repost your post in the community developer connected devices forum area because that is where we can get all the help for you from our other great dev guys like @kevintierney @tgauchat @tslagle13 @Sticks18 @erocm1231 These guys are super!
@HomeDepot get your retail stock in for this $50 controller please 
It is coming up on one year since you first teased us with it.
