I need to use GET requests to retrieve the current status of a device and then update the body of a specific Wordpress post with the text data sent by the external device (for reference, it will use the following format: "YYYY-MM-DD|HH:MM:SS|VALUE1|VALUE2").

Originally I was hoping to make the device send POST requests to Wordpress through the REST API, but the device doesn't support POST requests.

Any ideas? Maybe pass the result of the GET requests as arguments for WP-CLI commands, is that at all possible?

Any thoughts are appreciated.

EDIT: added clarifying info.
