thanks in advance  
i have struggled with this basic task for a while and i can do it so easily in the home assistant automations but i want it in node red as part of a larger flow.  
i have a temperature sensor continually fluctuating, and i want to switch on a fan only if the temperature is within a range for more that a minute  
(Not when it is under or over a number)

i have simplified my example  
"when temperature is between 30 and 40"- "for more that 1 minute"- "switch on fan"

i have tried timers and loops restricted messages and i keep getting lost

i couldn't use a delay because i need it different automation when the temperature goes out side the range, the delay node was just triggering the node late even if the temperature had moved outside the range  
i wasnt able to use the trigger node because the temperature was always changing and resetting the trigger timer

You can cancel the second, delayed message from a trigger node by sending msg.reset.  
Sending another temperature within the range doesn't retart the countdown.

Perhaps [the hysteresis node](https://flows.nodered.org/node/node-red-contrib-hysteresis) will help here, it allows you to set lower/upper thresholds and compares it to the previous value.
