Hi,

I am using a KNX sensor, It sends values (msg.payload) every 30 min, but sometimes it sends 2 msg in this duration. So I want to delete the second msg payload if is the case.  
Have you an idea?

Thank you for your help 🙂

Use delay node set to rate limit.

With 'drop intermediate messages'.

Also the RBE node may possibly be useful to you. It can suppress messages with a repeated payload so that if you get two the same only the first gets through.
