We've built a neat ethernet cappable ZigBee Coordinator for use with zigbee2mqtt, io.broker and alike. It can be bought here: https://shop.codm.de/automation/zigbee/40/zigbee-cc2652p2-tcp-ethernet-coordinator
It's based on the CC2652P2 ZigBee chip and the USR-K6 Serial Ethernet Gateway.
All in a small formfactor and a power draw as low as 0.8W.
This is the matching case for either printing or remixing.
The author marked this model as their own original creation.
