Number:Temperature Problems with IF/IF Else

[Vini]

I’m running openHAB 2.5.0 Build #1590 on a Pi3. No issues.

I’m struggling to get a rule to fire based on a Number:Temperature item, which is a Hue Motion Sensor.

I’m trying to trigger an “alarm” when the temperature exceeds XX degrees. The item is, as below.

This triggers an Event;

2019-05-15 13:41:00.588 [vent.ItemStateChangedEvent] - HueLoftTemperatureSensor_Temperature changed from 32.87 °C to 33.01 °C

Now… my rule;

rule "Loft Temperature over 25 Degrees"
when
    Item HueLoftTemperatureSensor_Temperature changed
then
	var LoftTemp = HueLoftTemperatureSensor_Temperature.state as Number
	if (LoftTemp>25.00)
	//if (Double::parseDouble(HueLoftTemperatureSensor_Temperature.state.toString) > 25.0)
	//if ((HueLoftTemperatureSensor_Temperature.state as Number) > 25.00)
		{
			sendMail("blah@pomail.net", "Loft Temperature Over 25", "Loft Temperature is currently "+HueLoftTemperatureSensor_Temperature.state)
			logInfo("EXTRA", "Loft Temperature is currently "+HueLoftTemperatureSensor_Temperature.state)
		}
	else if (LoftTemp<25.00)
	{
			sendMail("blah@pomail.net", "Loft Temperature Below 25", "Loft Temperature is currently "+HueLoftTemperatureSensor_Temperature.state)	
			logInfo("EXTRA", "Loft Temperature is currently " +HueLoftTemperatureSensor_Temperature.state)
	}
end

I’ve tried many variations. But what is not happening, is that the rule is not understanding < or >, and just triggering regardless. So I’m being told the item is over 25’c, when actually its not.

Any ideas?

What does the logInfo tell about the state of the item?

Hi @opus,

Is that this?

2019-05-15 13:41:00.588 [vent.ItemStateChangedEvent] - HueLoftTemperatureSensor_Temperature changed from 32.87 °C to 33.01 °C

I dn’t know if the degrees C symbol is breaking things, or if its the decimal. Its hurting my head though!

[SOLVED] Comparaison with OpenWeatherMap temperature

Your Item has UoM, Units of Measurement. So it’s effectively 15 °C not just 15, and comparing with just 12 is apples-and-oranges. This is one of the clumsier parts of UoM. You can either extract just-the-number or compare with a temperature. if( (localHourlyForecast12Temperature.state as QuantityType<Number>).intValue <= 12 ) if( localHourlyForecast12Temperature.state <= 12 | "°C" )

[opus (Jürgen Baginski)]

As @rossko57 posted, your item has UoM, you can see that in the received mail, the state is reported with the unit “°C”.
In the log you should also see the output of the logInfo line of your rule.

Thank you guys! I tried a few variations late last night, I knew I could rely on the community!

rule "Loft Temperature over 35 Degrees"
when
    Item HueLoftTemperatureSensor_Temperature changed
then
	if(HueLoftTemperatureSensor_Temperature.state >= 35 | "°C" )
		{
			sendMail("blah@pomail.net", "Loft Temperature Over 35", "Loft Temperature is currently "+HueLoftTemperatureSensor_Temperature.state)
			logInfo("EXTRA", "Loft Temperature is currently "+HueLoftTemperatureSensor_Temperature.state)
		}
	else if(HueLoftTemperatureSensor_Temperature.state < 35 | "°C" )
	{
			sendMail("blah@pomail.net", "Loft Temperature Below 35", "Loft Temperature is currently "+HueLoftTemperatureSensor_Temperature.state)	
			logInfo("EXTRA", "Loft Temperature is currently " +HueLoftTemperatureSensor_Temperature.state)
	}
end
