Setting an alarm with AmazonEchoControl binding

Is there any chance to set the nextAlarm with AmazonEchoControl? I’ve tried

Echo_NextAlarm.sendCommand(now.plusMinutes(10).toString)

The items gets updated, but on the next polling of the Echo state from network, it resets to the previous value.

Best regards,

You can see in the docs (https://www.openhab.org/addons/bindings/amazonechocontrol/) that the nextAlarm channel only is a Read Channel. Writing to it doesn’t do anything
