I have MQTT outside motion sensor that trigger speech to all Google Cast devices, this works great but I would like to limit the triggers or messages. It's enought to have a message once and if no motions are triggered for ex 5 minutes it should be ready to speak one more time. Now it's spamming the messaging. The motion sensor is sending out motion every time motion is detected. No nomotion info. How can I make a time window for this?

```auto

look at the trigger node (set to extend if more inputs arrive)
