I worked with Alice only through the Digma application. Not with the recommended one.
What I really liked: In the box with the gateway there was a wat-up phone number to help set it up. Help is working. We consulted. There were no problems.
Pros
Zigbee. Compact. Quick setup.
Cons
Haven't revealed yet. It does not work with the recommended application and with Alice. But it works through the Digma application with Alice.
