Garadget not responding to MQTT commands

I’m trying to get my Garadget set up with MQTT. I can use MQTT to receive status updates from the door, but when I send commands to it, it does not work. Issuing the same commands in the cloud interface work, so I know the wiring is done correctly. Since I’m receiving MQTT status updates, I think that is configured correctly, too.

I attached a screenshot showing a successful status update. You’ll see when I trigger the close command, nothing happens - the Garadget relay doesn’t click, and there is no MQTT status update for “closing”.
