@JDRoberts, the Hub v3 launched with Zigbee 3 support. In order to get Zigbee 3 certified we had to support the Green Power Proxy feature. However that alone does not let the hub communicate with a Green Power devices. In order to do that we need to be a Green Power sink or combo device and unfortunately the Zigbee stack we’re currently using doesn’t support that. My hope is to update the stack down the road to a newer version that has more Green Power support and then we should be able to support these Green Power devices.
