ALEXA "bodyweight 70kg" -> ? -> CLOUDMQTT -> HA database


I do not have a public IP and so I can not use alexa intents. My idea was to use cloudmqtt to control home assisant with my voice using alexa. I also want to send VALUES to the HA database. For example I want to say: “Alexa - store bodyweight 70 kg”.

I have no idea how to do this. I’ve tried but this script does not support to transmit values. Any ideas ?

Thanks ! Alex
