Cloud message send

An action block that sends a “cloud” message through the internet to another device running Automate.

If the proceed option is set to Immediately, then the message is enqueued for sending without pausing the fiber, a failure to send is silently ignored. If set to When sent, then the fiber will pause until the message has been successfully sent to the server, or failed to do so, this acknowledged that may not be immediate for each message. A failure to send will cause the fiber to stop unless Failure catch block is used.

Use a Cipher account, with a strong password, to ensure that only a recipient knowing the password can receive the message. The message is then encrypted on the sender device with a AES-GCM cipher using a key derived (PBKDF2) from the password. The encryption is end-to-end, the server are not involved and can’t access the password, nor the payload.

Messages can also be sent from any source capable of making HTTP(S) requests, see https://llamalab.com/automate/cloud/.

This block requires a device with a working Google Play services installed.
