Single value subflow to be used as filter after processing node
A subflow is a collection of nodes that are collapsed into a single node in the workspace. Detailed explanations are available in Node-Red documentation: Node-Red Subflows.
A subflow already exists in STM32CubeMonitor: the Single value subflow. It is available from the left menu. The purposes of this subflow are the following:
- Data filtering to extract only one variable after the "processing node" step .
- Modifying the message to fit with standard widgets such as gauges.
- Limiting the number of messages to a maximum of 10 msg per second.
Details of the subflow are available by double-clicking the image below:
This template can be modified, for example to increase or reduce the number of message per second. It impacts all the single value subflows already used in your current flows.
