On the HTTP input node I receives triggers from my video surveillance system (motion detection) and to notify activity via pushover or email depending on the query parameter received.
In some cases, like when outdoor lights are switched on/off this triggers the video to detect a motion.
I control the lights via home automation and I would like to send a HTTP request to this node before the lights turns ON/OFF and ignore the other HTTP requests for e.g. 10 sec and hence avoid the false notifications.
Have a look at node-red-contrib-simple-gate which can be used to block messages, then use a Trigger node to send the block message to the gate, then the release message a defined time later.
