Hi,
I’m migrating from OH2 to OH4. I’ve noticed a strange behaviour when writing a rule. This simple code fails and is not executed

val Number ECS_Temp_hyst = 1.0|°C
val Number ECS_Temp_maxvalid = 90|°C
val Number ECS_Temp_minvalid = 0|°C
logInfo ("ECS","Script start")
logInfo ("ECS_Temp_hyst",ECS_Temp_hyst.toString())
var TempCorrect = ( ( ECSTemperatureHaut.state != UNDEF ) && ( ECSTemperatureHaut.state != NULL ) )
TempCorrect = TempCorrect && ( ECSTemperatureHaut.state as Number > ECS_Temp_minvalid )
TempCorrect = TempCorrect && ( ECSTemperatureHaut.state as Number < ECS_Temp_maxvalid )
if (TempCorrect) {logInfo ("ECS","Températures correctes")}

but is I change one comparison ‘<’ to ‘>’ in ECSTemperatureHaut.state as Number < ECS_Temp_maxvalid it works like a charm

val Number ECS_Temp_hyst = 1.0|°C
val Number ECS_Temp_maxvalid = 90|°C
val Number ECS_Temp_minvalid = 0|°C
logInfo ("ECS","Script start")
logInfo ("ECS_Temp_hyst",ECS_Temp_hyst.toString())
var TempCorrect = ( ( ECSTemperatureHaut.state != UNDEF ) && ( ECSTemperatureHaut.state != NULL ) )
TempCorrect = TempCorrect && ( ECSTemperatureHaut.state as Number > ECS_Temp_minvalid )
TempCorrect = TempCorrect && ( ECS_Temp_maxvalid > ECSTemperatureHaut.state as Number  )
if (TempCorrect) {logInfo ("ECS","Températures correctes")}

and I don’t understand why.

Thank you for your help.

Thank you for your answer. It work now!
