Toolkit for Node-RED

This toolkit provides a set of useful nodes for Node-RED to help with various tasks, including network ping checks, message filtering based on whitelists and blacklists, and text transformations.

Nodes

Ping

Performs a ping to a specified host and returns whether the host is online along with the latency.

Blacklist

Filters messages based on a configured blacklist of strings. If a string from the blacklist is found in the payload or topic, the message is blocked.

Whitelist

Filters messages based on a configured whitelist of strings. Only messages that contain the specified strings in the payload or topic are allowed through.

Watchdog

Monitors incoming messages and expects a true payload within a specified time interval. If not received, it outputs false. Status and configuration can be set within the node.

Replace Umlauts

Replaces German umlauts in the payload of a message with their respective digraphs (e.g., ä -> ae, ö -> oe, ü -> ue).

Restore Umlauts

Restores German umlauts in the payload of a message from their respective digraphs (e.g., ae -> ä, oe -> ö, ue -> ü).

Upper Case

Converts the payload of a message to upper case.

Lower Case

Converts the payload of a message to lower case.
