How it works

The factoryinput microservice provides REST endpoints for MQTT messages via HTTP requests.

The main endpoint is /api/v1/{customer}/{location}/{asset}/{value}, with a POST request method. The customer, location, asset and value are all strings. And are used to build the MQTT topic. The body of the HTTP request is used as the MQTT payload.
