Send reset to a trigger node

i do check for a device if the ping is false i got a Telegram Message!
because i don't like to get every 30Second a Message i have added a trigger Node to wait 180min.

I have a manual inject Node with the msg.reset and true this will reset the trigger Node.

i would like to have a "switch?" if ping time is >1 the the trigger should be reseted

how should this be done?

have a nice day

Not sure if I fully understand your question, but have you looked at a 'delay' node set to rate limit, instead of a 'trigger' node?
Then you will only get 1 alert in any time period that you wish.


merci @Paul-Reed
my trigger node do the same - but with a inject node you can brake this delay.

imagine you ping a device (all 30s) - device is out of service - so i would get all 30sec a Telegram Information.
So I add inbetween the trigger node and then it wait 180min for the next message.
but with the inject i could brak it.
So now i would liket to have a Node (if ping result over 1 (so it is not false) then reset the trigger for the delay

You can use a Switch to check for ping OK and then feed that into a Change node to set msg.reset, as in the flow below.
If you already have a Switch node to detect the ping failed and use that to start the trigger then you can probably use the Otherwise case in the switch rather than use another Switch

thanks a lot - more then perfect!
i did add the information to my switch and added your change Node and it works perfect.
device is off i got a telegram Message telling me then wait 3h.
as soon changed the battery i comes back to life and the trigger node is resetted.
