- Platform information:
- Hardware: _ Raspberry Pi 3 Model B Rev 1.2_
- OS: Raspbian GNU/Linux 8 (jessie)
- Java Runtime Environment: (Zulu Embedded 8.25.0.76-linux-aarch32hf) (build 1.8.0_152-b76)
- openHAB version: openHAB 2.3.0-1 (Release Build) / OH 2.4.0.M4
- Bindings:Astro, AVM, EXEC, MQTT, Network, NTP, Samsung, Sonos, Weather (binding-weather1 - 1.12.0), MapDB-Persitence
- Transformations: exec, Javascript, JSONPATH, Map, RegEx, Scale
On Startup the Rule below should run:
val String filename = "startup-rules"
rule "Look for Raspi_Office is online"
when
System started
then
logInfo (filename, "CPU TEMP " + "Line 1: " + CPU_RasPi_Temp_num ) // Test-Switch
logInfo (filename, "CPU TEMP " + "Line 2: " + CPU_RasPi_Temp ) // Test-Switch
end
/* createTimer(now.plusSeconds(180), [|
if (RasPi_online.state == OFF && CPU_RasPi_Temp_num.state != 0)
{
CPU_RasPi_Temp_num.postUpdate(0)
logInfo (filename, "Raspi ist offline " + ":" + " " + CPU_RasPi_Temp_num)
}
else {
logInfo (filename, "Raspi ist online oder 0 ")
}
logInfo (filename, "Raspberry-Status ist " + ": " + CPU_RasPi_Temp_num)
])
end
*/
I have marked out the tail of the Rule only to see how often the Rule is triggered on Start and when running. This Rule should look if another Raspberry is running and online and if not it should initialize the item"CPU_RasPi_Temp_num" with Zero. In this Version it only gives a LogInfo.

I donât understand that the Rule triggers three times at start and later when a .items-file is updated it fires too !!??. Does OpenHAB see a .items-change as a start ? The behavior occurs in both OH-Versions
Has anyone an idea or can explain me what happens there ?
