okay thank for the clarification @Confused
i found this “tutorial” on github and got this so far:
but i needed to make some little adjustments in the rule - i changed:
(new DecimalType(acc)) to (acc)
(new PercentType(batt)) to (batt)
my rule now:
import org.openhab.core.library.types.*
rule "Mqtt Postion Parse Philipp"
when
Item mqttPositionPhilippRaw received update
then
val String json = (mqttPositionPhilippRaw.state as StringType).toString
val String type = transform("JSONPATH", "$._type", json)
if (type == "location") {
val String lat = transform("JSONPATH", "$.lat", json)
val String lon = transform("JSONPATH", "$.lon", json)
val String acc = transform("JSONPATH", "$.acc", json)
val String batt = transform("JSONPATH", "$.batt", json)
mqttPhilippLatitude.postUpdate(lat)
mqttPhilippLongitude.postUpdate(lon)
locationPhilipp.postUpdate(new PointType(lat + "," + lon))
mqttPhilippAccuracy.postUpdate(acc)
mqttPhilippBattery.postUpdate(batt)
logInfo("ownTRACKS=", +mqttPositionPhilippRaw.state)
}
end
on github patrik had this changes:
mqttPatikAccuracy.postUpdate(new DecimalType(acc))
mqttBattery.postUpdate(new PercentType(batt))
and i get this in the log:
