Device Service currently requires clients to supply their own Matter SDK library implementation for Matter support
Zigbee(Roadmap)
For Zigbee support, Device Service requires a separate runtime program that implements an abstraction library called zhal. Currently Barton provides a program called ZigbeeCore which implements zhal for Silicon Labs efr32 devices
If Device Service is built with Zigbee support there should be an implementation of ZHAL, which is the Zigbee Hardware Abstraction Layer. The intent of ZHAL is to enable portability to different Zigbee stack and silicon vendors
