Disable/Enable Thing with Rule (The name 'Java' cannot be resolved to an item or type)

Setup, Configuration and Use Scripts & Rules

Hi,

i try to start and stop things via item.
I use OH 4.3.1.

rule "reboot ebus Thing"
when 
	Item restartEBUS_THING changed
then 
	var ThingUID = Java.type('org.openhab.core.thing.ThingUID');
	if(restartEBUS_THING.state == ON){	
		thingMgr.setEnabled(new ThingUID('androiddebugbridge:android:1e12b02f269d'), false);
	}else{

		thingMgr.setEnabled(new ThingUID('androiddebugbridge:android:1e12b02f269d'), true);
	}
end

But when i try to execute i got this errormessage.

failed: The name 'Java' cannot be resolved to an item or type;

Do you know maybe why?

thank you but do you also know how to use it in *.rule file without Blockly or JS Scripting?

As said in the thread, you can’t use DSL rules for that.

things.getThing(‘bluetooth:goveeHygrometerMonitor:hci0:a4c138b16332’).setEnabled(false)

That’s not DSL, or is it?

It’s for Javascript.

No, but I found (a long time ago) a solution through the REST api in this forum:

enable:


var headers = new java.util.HashMap()
headers.put("Authorization", "Bearer " + "oh.restapi.mbE6fCExxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
sendHttpPutRequest("http://192.168.2.212:8080/rest/things/bsblan:bridge:heating/enable", "text/plain", 'true', headers, 5000)

disable:

var headers = new java.util.HashMap()
headers.put("Authorization", "Bearer " + "oh.restapi.mbE6fCExxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
sendHttpPutRequest("http://192.168.2.212:8080/rest/things/bsblan:bridge:heating/enable", "text/plain", 'false', headers, 5000)

sometimes it is working sometimes i got this error:

Fatal transport error: java.util.concurrent.TimeoutException: Total timeout 5000 ms elapsed

do you know why i got sometimes this error?

It looks like your connection isn’t stable if that command works only from time to time …

11

i check it again and it is working for enable the thing but not disable

12

Make sure you have the correct syntax: in both cases it is .../enable... with true for enable and false for disable

i using the right syntax but i forgot to change the IP Adress. My fault :see_no_evil:
