Is there anyway to use directly 433 with openhab --- serial gateway will be 433 receiver and transmitter (without mysensors lib and devices)
@static418 Thank you for your idea.
Create 2 maps, if one is null then get other map.
I removed ";" things because i dont need them.
var HashMap<String, String> CodeToItemsMapOn = newLinkedHashMap(
    "14013452"->"SOKET_1",
    "SOKET_1"->"14013452" 
    )
    var HashMap<String, String> CodeToItemsMapOff = newLinkedHashMap(
	"14013443"->"SOKET_1",
    "SOKET_1"->"14013443"
    )			
var HashMap<String, String> CodeToActionMap = newLinkedHashMap( //nothing important because there is no duplicate
    "14013452"->"ON",
    "ON"->"14013452",
    "14013443"->"OFF",
    "OFF"->"14013443"
    )  
//remember hashmaps must be out of the rule
rule "Arduino sends to Openhab"
    when
        Item Arduino received update
    then
.........
	if(subType==V_VAR1){
		var myOrder=CodeToItemsMapOn.get(msg) //1.map
		if(myOrder==null){myOrder=CodeToItemsMapOff.get(msg)} //2.map
		
		postUpdate(myOrder,CodeToActionMap.get(msg)) //make you job
	}
.......
end
This code is only for updating the openhab screen (receiving), i will work for transmit.
You can find more on https://github.com/openhab/openhab/wiki/Taking-Rules-to-New-Heights
There is another problem with CodeToActionMap; If i got a lot of outlets this means many on and off commands ..
rule "MY ON"
	when
		Item SOKET_1 received command ON
	then
				sendCommand(Arduino, "105;105;1;0;24;" + 14013452  + "\n")
	end
	
rule "MY OFF"
	when
		Item SOKET_1 received command OFF
	then
				sendCommand(Arduino, "105;0;1;0;24;" + 14013443 + "\n")
	end`
These rules for TRANSMIT didnt work any idea???
