Each process has a single main Input that is regularly tested for the switching Events.
In the Input section, users can configure what information should be obtained for further processing.
Example of process input
The Input source allows users to choose the primary Peripheral,
and if a digital GPIO is selected, the Channel option enables differentiation between various values available on the same Peripheral, if applicable.
In addition, there are three more options dedicated to publishing live readings to the MQTT broker,
including Allowing publishing, setting the Frequency for sending these messages,
and embedding the process name into the message topic using the Subtopic button.
See the MQTT telemetry and Input settings for further details.
A process can still be useful even without a defined Input.
For instance, it can be operated exclusively via Constraints using the Force On/Off options
or controlled externally by the user or third-party commands.
