[Solved] Need help to set up a condition

Hi all,

I made a gateway with an exisiting domotica system (bticino/legrand)
It works well but sometimes the gateway (which is written in java and runs on a NAS) is not responding.

I don’t know how to make a condition that would trigger when the temperature of a room has not change for say 5 hours in row?

Input:

RoomTemp - Bound to the temperature sensor you want to monitot

Condition:
NoChangeAlert RoomTemp; NOW > 5:00:00

I knew that should be easy ;D ;D

Thanks !
