Brian says that he's having issues with his internet connected door lock. It's connected to a ZigBee hub, and it's only 11 feet away from the door lock and the hub is hardwired to the router. The company's support told him he'll need to get a repeater. Leo says there are routers coming out now that have Zigbee built-in, which could be one solution to these problems. Ultimately the real solution is that these things won't be using ZigBee or Z-Wave, the devices will be talking to the Google Hub or Apple HomeKit. Leo also says that the lock probably works with the Echo, and there's a skill for it.
