How to use rbe-node with multiple sensors

Hi Node-RED experts

I'm using Node-RED to develop a flow for sending alarms (SMS), when values exceed a certain threshold. In the flow I'm using the rbe-node to prevent alarms being send every time payload arrives. It works fine with one sensor, but not with multiple sensors! Any idea how to solve this - so the rbe-node kan dinstinguish between values (e.g. temperature) from different sensors?

Thanks in advance!

If you make sure the message from each sensor has a unique topic (so topics are "sensor1", "sensor2" or other unique strings) then the RBE node will work separately for each topic.

Thanks a lot, Colin :+1: I'll try that!
