Rain notification flow

Hi everyone,

I have a flow set up to notify me (through speech, currently also a push notification to follow up on the amount of notifications) when it is going to rain, using the buienalarm app. However, I find it annoying that sometimes the current flow triggers twice (or even more) within the same 10 minutes.

Anyone that can give me some advice on how to optimalize this? (maybe using countdown, maybe a variable, …?)

Thanks in advance!

Add a10 minute timer started after an notification and only send a new message if timer is 0
