Hello,
Thank you for your question.
At this moment there is no feature that would allow to modify digital outputs through AWS using MQTT protocol that is enabled in Firmware.
For more detailed information and implementation about the MQTT and AWS please reach out to us via VIP Helpdesk or contact your sales manager/distributor. If you don't have any contacts with our Sales managers, please contact them on our official website
