fix openhab error: Rule ‘[rulename]’: An error occurred during the script execution: index=0, size=0

My goal is to execute an python-script when the Battery-charge has reached 70%

My rule was not executed, the error as shown above is seen in the log.
My faulty script:

rule "BYD 70"

when
     Item KOSTALPLENTICOREPlus70WithBattery_BatteryCharge received update



then
	var BYDBat = (KOSTALPLENTICOREPlus70WithBattery_BatteryCharge.state as Number).floatValue

	if ((KOSTALPLENTICOREPlus70WithBattery_BatteryCharge.state as Number).floatValue = 70.0) {


	sendTelegram("bot1",
            "BYD hat > 70  % Ladung " + BYDBat)
	executeCommandLine("python3 /etc/openhab2/scripts/BYDI.py")
	logDebug("logtest", "BYDBat = " + BYDBat)
        logDebug("logtest", "state = " + KOSTALPLENTICOREPlus70WithBattery_BatteryCharge.state)
}

end

Reason of the error: the if-statement is misleading, to check if the value is equal it needs two “==”:


	if ((KOSTALPLENTICOREPlus70WithBattery_BatteryCharge.state as Number).floatValue == 70.0) {

working-code:

rule "BYD 70"

when
     Item KOSTALPLENTICOREPlus70WithBattery_BatteryCharge received update



then
	var BYDBat = (KOSTALPLENTICOREPlus70WithBattery_BatteryCharge.state as Number).floatValue

	if ((KOSTALPLENTICOREPlus70WithBattery_BatteryCharge.state as Number).floatValue == 70.0) {


	sendTelegram("bot1",
            "BYD hat > 70  % Ladung " + BYDBat)
	executeCommandLine("python3 /etc/openhab2/scripts/BYDI.py")
	logDebug("logtest", "BYDBat = " + BYDBat)
        logDebug("logtest", "state = " + KOSTALPLENTICOREPlus70WithBattery_BatteryCharge.state)
}

end

to debug BYDBat/KOSTALPLENTICOREPlus70WithBattery_BatteryCharge.state debugging needs to be enabled like shown at: https://www.cipv6.de/worp/index.php/2019/10/23/how-do-i-debug-tradfri-on-openhab/

Send Geo-location from Browser

Create a button and log the current LAT/LON when the button is pressed:

<button id="send-location"> Send location</button>
document.querySelector('#send-location').addEventListener('click', () => {

    if (!navigator.geolocation) {

        return alert ('Geolocation not supported by Browser !')

    }
    
    navigator.geolocation.getCurrentPosition((position) => {

        console.log(position)

    })

console.log output

Java: Remove brackets / leading slashes from String

My Android-app have always presented the DNS-Server(s) with brackets / leading slashes like:

How can we get rid of these unnecessary characters ?

String myIp2Dns1:

String myIp2Dns1 = String.valueOf (LinkProp.getDnsServers()) ;

Log:

Log.d("myDnsInfo - Domain - ", "Domain = " + LinkProp.getDomains());
D/myDnsInfo: dns = [/10.0.2.3]

Solution:
Manipulation of String myIp2Dns1:

myIp2Dns1 = myIp2Dns1.replaceAll("[\\[\\](){}\"^/+\"]","");

This command removes brackets / slashes / backslashes from the String.

The output looks much better now:
