Node Red Timeout
A simple timeout by Peter Scargill ([email protected]). After setting the topic and both safe and unsafe messages, for, for example MQTT (or simply puttting 1 and 0 into the two messages) the node is triggered by any input and will send the SAFE message out. If continually triggered nothing more will happen but if allowed to timeout, the UNSAFE message will be sent. Hence this can be used as a watchdog. You can also set a warning message at any arbitrary point in the count - and optionally repeat messages every second.
