Can´t create basic rule

Setup, Configuration and Use Scripts & Rules

Hi everyone.

I´m trying to create my first rule which will eventually (when I get it working) will send temperature and humidity updates to Thinkgspeak.

Items:
Number office_temp "Temperatura [%.1f ºC]" <temperature> (grpOffice) {mqtt="<[mosquitto:office/sensor/temp:state:default]"} Number office_hum "Humedad [%.1f %%]" <humidity> (grpOffice) {mqtt="<[mosquitto:office/sensor/hum:state:default]"}

Rule:

import org.joda.time.*

rule "Send data to Thingspeak"
    when
		Time cron "1 0/1 * * * ?"
    then
		logInfo("Thingspeak", office_temp.state)
		logInfo("Thingspeak", "Temp & Hum sent to Thingspeak")
end

If I uncomment this line: logInfo("Thingspeak", office_temp.state), then I get:

2016-05-04 18:36:01.072 [ERROR] [.o.m.r.i.engine.ExecuteRuleJob] - Error during the execution of rule Send data to Thingspeak

What´s wrong with it?

TIA

I’ve seen some issues with the Rule’s DSL being able to autoconvert things to Strings like it used to. Try:

logInfo("Thingspeak", office_temp.state.toString)

Thank you Rich, that did the trick!
