As i understand i need Xbee S3 for HA profile. But i have some other things in my mind. For example in my project i plan to use one xbee s3 as coordinator and a couple as router and afew as end devices. Some of these routers or end devices will be interfaced with some mcu(such as pic series) to control other things. Also i thought about using some Zigbee HA light switch of a brand. Since it is HA profile i can use it with Xbee S3 right? But whats bugging me that in this case how should i configure coordinator, router and end devices to use HA light switch and other routers/end devices interfaced with mcu? Should all be in HA profile, or something else? I'm confused about this. I would also appreciate me if you guide any docs references.
