What do i need to run Alexa or google voice command to KinCony?
Do i need a certain module for each controller all one for all controllers in the same electric panel?
Assume all my systems are 
KC-868-H32BS with omron relay 250v 16 A
KC-868-H32B with smart buttons

suggest add a raspberry pi running Node-Red, so that your all controller can voice control by alexa or google home. not need every controller connect with a voice module. just let all controller and raspberry pi connect to same network.
