As a prototype - a good development. As a commercial smart home system, it is of no interest. I had to sell on ebay on the first day after purchase. Has pros: They made the hub as a separate device. There are sms and push notifications in scripts. Got cons: "Local scripts" do not work without the Internet. Even "local scripts" work with a big lag. Zigby button + lamp = second lag. The list of supported devices is extremely limited. There is no local interaction with the most popular yeelight fixtures on the market. The functionality of the scripts is poor, and the interface for setting them up is inconvenient. There are no home security modes out of the box, as it has been done for a long time by all other smart home vendors. The number of sms/push notifications is limited to 50 pieces. Two-gang/three-gang switches are not supported as a phenomenon. Constantly loses the network with aqara motion sensors, which are declared to be supported. For such meager functionality - expensive.
