Hi I’m a noob at openhab. Trying to configure a rule that will turn on the heating at a preset temperature I get the following error message in the openhab.log,
2015-11-11 00:22:14.971 [ERROR] [o.o.c.s.ScriptExecutionThread ] - Error during the execution of rule 'Control Kitchen heater': The name '<XFeatureCallImplCustom> < <XNumberLiteralImpl>' cannot be resolved to an item or type.
I don’t seem to be able to figure out what is causing this.
My rules file is,
import org.openhab.core.library.types.*
import org.openhab.core.persistence.*
import org.openhab.model.script.actions.*
import org.joda.time.*
/* Turn on Kitchen heater when temp is below 21 degrees */
rule "Control Kitchen heater"
when
Item Temperature_GF_Kitchen received update
then
if (Temperature_GF_Kitchen < 27)
postUpdate(Heating_GF_Kitchen, ON)
else
postUpdate(Heating_GF_Kitchen, OFF)
end
Three possibilities: (1) you do not have an item defined, (2) you have one defined but it is the wrong type and/or a type mismatch (Number (in ITEMS) vs integer (in rule-cf 27 not 27.0), or (3) at the time the rule executes (and I think received update would trigger at startup - might be wrong ) the update is to “Uninitialized” rather than a number–so the comparison in the THEN clause would fail on a type mismatch. Add a logDebug message as first line in THEN clause to print current value of the Temperature_GF_Kitchen when rule executes
