Thanks for the info, I understand the whole business side of selling the drivers and the cost incurred ect, This system is just my home system for testing and demo.
I Was hoping to get a bit more experience with writing drivers to help me understand more about how these drivers work and how to create them.
I have got a bit disillusioned with the ability of integrating Control4 in retrofit systems, I can get more control over my system using apps and Alexa, I was hoping it would have been an easier and cleaner integration.
Im not saying Control4 has not got a place in the world of integration but just not in retro fitting, it would be great if all clients let us spec their whole house but most have a preferred brand or an existing system they want.
The reason for wanting to create the drivers myself is to understand what is going on within a driver and to have control over what that driver does.
